+## 6.0.0 (2022-06-08)
+
+### Bug fixes
+
+Fix a bug where by-page selection commands sometimes moved one line too far.
+
+## 0.20.0 (2022-04-20)
+
+### Breaking changes
+
+There is no longer a separate `commentKeymap`. Those bindings are now part of `defaultKeymap`.
+
+### Bug fixes
+
+Make `cursorPageUp` and `cursorPageDown` move by window height when the editor is higher than the window.
+
+Make sure the default behavior of Home/End is prevented, since it could produce unexpected results on macOS.
+
+### New features
+
+The exports from @codemirror/comment are now available in this package.
+
+The exports from the @codemirror/history package are now available from this package.
+
+## 0.19.8 (2022-01-26)
+
+### Bug fixes
+
+`deleteCharBackward` now removes extending characters one at a time, rather than deleting the entire glyph at once.
+
+Alt-v is no longer bound in `emacsStyleKeymap` and macOS's `standardKeymap`, because macOS doesn't bind it by default and it conflicts with some keyboard layouts.
+
+## 0.19.7 (2022-01-11)
+
+### Bug fixes
+
+Don't bind Alt-\< and Alt-> on macOS by default, since those interfere with some keyboard layouts. Make cursorPageUp/Down scroll the view to keep the cursor in place
+
+`cursorPageUp` and `cursorPageDown` now scroll the view by the amount that the cursor moved.
+
+## 0.19.6 (2021-12-10)
+
+### Bug fixes
+
+The standard keymap no longer overrides Shift-Delete, in order to allow the native behavior of that key to happen on platforms that support it.
+
+## 0.19.5 (2021-09-21)
+
+### New features
+
+Adds an `insertBlankLine` command which creates an empty line below the selection, and binds it to Mod-Enter in the default keymap.
+
+## 0.19.4 (2021-09-13)
+
+### Bug fixes
+
+Make commands that affect the editor's content check `state.readOnly` and return false when that is true.
+
+## 0.19.3 (2021-09-09)
+
+### Bug fixes
+
+Make by-line cursor motion commands move the cursor to the start/end of the document when they hit the first/last line.
+
+Fix a bug where `deleteCharForward`/`Backward` behaved incorrectly when deleting directly before or after an atomic range.
+
+## 0.19.2 (2021-08-24)
+
+### New features
+
+New commands `cursorSubwordForward`, `cursorSubwordBackward`, `selectSubwordForward`, and `selectSubwordBackward` which implement motion by camel case subword.
+
+## 0.19.1 (2021-08-11)
+
+### Bug fixes
+
+Fix incorrect versions for @lezer dependencies.
+
+## 0.19.0 (2021-08-11)
+
+### Breaking changes
+
+Change default binding for backspace to `deleteCharBackward`, drop `deleteCodePointBackward`/`Forward` from the library.
+
+`defaultTabBinding` was removed.
+
+### Bug fixes
+
+Drop Alt-d, Alt-f, and Alt-b bindings from `emacsStyleKeymap` (and thus from the default macOS bindings).
+
+`deleteCharBackward` and `deleteCharForward` now take atomic ranges into account.
+
+### New features
+
+Attach more granular user event strings to transactions.
+
+The module exports a new binding `indentWithTab` that binds tab and shift-tab to `indentMore` and `indentLess`.
+
+## 0.18.3 (2021-06-11)
+
+### Bug fixes
+
+`moveLineDown` will no longer incorrectly grow the selection.
+
+Line-based commands will no longer include lines where a range selection ends right at the start of the line.
+
+## 0.18.2 (2021-05-06)
+
+### Bug fixes
+
+Use Ctrl-l, not Alt-l, to bind `selectLine` on macOS, to avoid conflicting with special-character-insertion bindings.
+
+Make the macOS Command-ArrowLeft/Right commands behave more like their native versions.
+
+## 0.18.1 (2021-04-08)
+
+### Bug fixes
+
+Also bind Shift-Backspace and Shift-Delete in the default keymap (to do the same thing as the Shift-less binding).
+
+### New features
+
+Adds a `deleteToLineStart` command.
+
+Adds bindings for Cmd-Delete and Cmd-Backspace on macOS.
+
+## 0.18.0 (2021-03-03)
+
+### Breaking changes
+
+Update dependencies to 0.18.
+
+## 0.17.5 (2021-02-25)
+
+### Bug fixes
+
+Use Alt-l for the default `selectLine` binding, because Mod-l already has an important meaning in the browser.
+
+Make `deleteGroupBackward`/`deleteGroupForward` delete groups of whitespace when bigger than a single space.
+
+Don't change lines that have the end of a range selection directly at their start in `indentLess`, `indentMore`, and `indentSelection`.
+
+## 0.17.4 (2021-02-18)
+
+### Bug fixes
+
+Fix a bug where `deleteToLineEnd` would delete the rest of the document when at the end of a line.
+
+## 0.17.3 (2021-02-16)
+
+### Bug fixes
+
+Fix an issue where `insertNewlineAndIndent` behaved strangely with the cursor between brackets that sat on different lines.
+
+## 0.17.2 (2021-01-22)
+
+### New features
+
+The new `insertTab` command inserts a tab when nothing is selected, and defers to `indentMore` otherwise.
+
+The package now exports a `defaultTabBinding` object that provides a recommended binding for tab (if you must bind tab).
+
+## 0.17.1 (2021-01-06)
+
+### New features
+
+The package now also exports a CommonJS module.
+
+## 0.17.0 (2020-12-29)
+
+### Breaking changes
+
+First numbered release.

+## 6.0.0 (2022-06-08)
+
+### New features
+
+The `foldingChanged` option to `foldGutter` can now be used to trigger a recomputation of the fold markers.
+
+## 0.20.2 (2022-05-20)
+
+### Bug fixes
+
+List style-mod as a dependency.
+
+## 0.20.1 (2022-05-18)
+
+### Bug fixes
+
+Make sure `all` styles in the CSS generated for a `HighlightStyle` have a lower precedence than the other rules defined for the style. Use a shorthand property
+
+## 0.20.0 (2022-04-20)
+
+### Breaking changes
+
+`HighlightStyle.get` is now called `highlightingFor`.
+
+`HighlightStyles` no longer function as extensions (to improve tree shaking), and must be wrapped with `syntaxHighlighting` to add to an editor configuration.
+
+`Language` objects no longer have a `topNode` property.
+
+### New features
+
+`HighlightStyle` and `defaultHighlightStyle` from the now-removed @codemirror/highlight package now live in this package.
+
+The new `forceParsing` function can be used to run the parser forward on an editor view.
+
+The exports that used to live in @codemirror/matchbrackets are now exported from this package.
+
+The @codemirror/fold package has been merged into this one.
+
+The exports from the old @codemirror/stream-parser package now live in this package.
+
+## 0.19.10 (2022-03-31)
+
+### Bug fixes
+
+Autocompletion may now also trigger automatic indentation on input.
+
+## 0.19.9 (2022-03-30)
+
+### Bug fixes
+
+Make sure nodes that end at the end of a partial parse aren't treated as valid fold targets.
+
+Fix an issue where the parser sometimes wouldn't reuse parsing work done in the background on transactions.
+
+## 0.19.8 (2022-03-03)
+
+### Bug fixes
+
+Fix an issue that could cause indentation logic to use the wrong line content when indenting multiple lines at once.
+
+## 0.19.7 (2021-12-02)
+
+### Bug fixes
+
+Fix an issue where the parse worker could incorrectly stop working when the parse tree has skipped gaps in it.
+
+## 0.19.6 (2021-11-26)
+
+### Bug fixes
+
+Fixes an issue where the background parse work would be scheduled too aggressively, degrading responsiveness on a newly-created editor with a large document.
+
+Improve initial highlight for mixed-language editors and limit the amount of parsing done on state creation for faster startup.
+
+## 0.19.5 (2021-11-17)
+
+### New features
+
+The new function `syntaxTreeAvailable` can be used to check if a fully-parsed syntax tree is available up to a given document position.
+
+The module now exports `syntaxParserRunning`, which tells you whether the background parser is still planning to do more work for a given editor view.
+
+## 0.19.4 (2021-11-13)
+
+### New features
+
+`LanguageDescription.of` now takes an optional already-loaded extension.
+
+## 0.19.3 (2021-09-13)
+
+### Bug fixes
+
+Fix an issue where a parse that skipped content with `skipUntilInView` would in some cases not be restarted when the range came into view.
+
+## 0.19.2 (2021-08-11)
+
+### Bug fixes
+
+Fix a bug that caused `indentOnInput` to fire for the wrong kinds of transactions.
+
+Fix a bug that could cause `indentOnInput` to apply its changes incorrectly.
+
+## 0.19.1 (2021-08-11)
+
+### Bug fixes
+
+Fix incorrect versions for @lezer dependencies.
+
+## 0.19.0 (2021-08-11)
+
+### Breaking changes
+
+CodeMirror now uses lezer 0.15, which means different package names (scoped with @lezer) and some breaking changes in the library.
+
+`EditorParseContext` is now called `ParseContext`. It is no longer passed to parsers, but must be retrieved with `ParseContext.get`.
+
+`IndentContext.lineIndent` now takes a position, not a `Line` object, as argument.
+
+`LezerLanguage` was renamed to `LRLanguage` (because all languages must emit Lezer-style trees, the name was misleading).
+
+`Language.parseString` no longer exists. You can just call `.parser.parse(...)` instead.
+
+### New features
+
+New `IndentContext.lineAt` method to access lines in a way that is aware of simulated line breaks.
+
+`IndentContext` now provides a `simulatedBreak` property through which client code can query whether the context has a simulated line break.
+
+## 0.18.2 (2021-06-01)
+
+### Bug fixes
+
+Fix an issue where asynchronous re-parsing (with dynamically loaded languages) sometimes failed to fully happen.
+
+## 0.18.1 (2021-03-31)
+
+### Breaking changes
+
+`EditorParseContext.getSkippingParser` now replaces `EditorParseContext.skippingParser` and allows you to provide a promise that'll cause parsing to start again. (The old property remains available until the next major release.)
+
+### Bug fixes
+
+Fix an issue where nested parsers could see past the end of the nested region.
+
+## 0.18.0 (2021-03-03)
+
+### Breaking changes
+
+Update dependencies to 0.18.
+
+### Breaking changes
+
+The `Language` constructor takes an additional argument that provides the top node type.
+
+### New features
+
+`Language` instances now have a `topNode` property giving their top node type.
+
+`TreeIndentContext` now has a `continue` method that allows an indenter to defer to the indentation of the parent nodes.
+
+## 0.17.5 (2021-02-19)
+
+### New features
+
+This package now exports a `foldInside` helper function, a fold function that should work for most delimited node types.
+
+## 0.17.4 (2021-01-15)
+
+## 0.17.3 (2021-01-15)
+
+### Bug fixes
+
+Parse scheduling has been improved to reduce the likelyhood of the user looking at unparsed code in big documents.
+
+Prevent parser from running too far past the current viewport in huge documents.
+
+## 0.17.2 (2021-01-06)
+
+### New features
+
+The package now also exports a CommonJS module.
+
+## 0.17.1 (2020-12-30)
+
+### Bug fixes
+
+Fix a bug where changing the editor configuration wouldn't update the language parser used.
+
+## 0.17.0 (2020-12-29)
+
+### Breaking changes
+
+First numbered release.

+## 6.0.0 (2022-06-08)
+
+### Bug fixes
+
+Don't crash when a custom search panel doesn't have a field named 'search'.
+
+Make sure replacements are announced to screen readers.
+
+## 0.20.1 (2022-04-22)
+
+### New features
+
+It is now possible to disable backslash escapes in search queries with the `literal` option.
+
+## 0.20.0 (2022-04-20)
+
+### Bug fixes
+
+Make the `wholeWords` option to `highlightSelectionMatches` default to false, as intended.
+
+## 0.19.10 (2022-04-04)
+
+### Bug fixes
+
+Make sure search matches are highlighted when scrolling new content into view.
+
+## 0.19.9 (2022-03-03)
+
+### New features
+
+The selection-matching extension now accepts a `wholeWords` option that makes it only highlight matches that span a whole word. Add SearchQuery.getCursor
+
+The `SearchQuery` class now has a `getCursor` method that allows external code to create a cursor for the query.
+
+## 0.19.8 (2022-02-14)
+
+### Bug fixes
+
+Fix a bug that caused the search panel to start open when configuring a state with the `search()` extension.
+
+## 0.19.7 (2022-02-14)
+
+### Breaking changes
+
+`searchConfig` is deprecated in favor of `search` (but will exist until next major release).
+
+### New features
+
+The new `search` function is now used to enable and configure the search extension.
+
+## 0.19.6 (2022-01-27)
+
+### Bug fixes
+
+Make `selectNextOccurrence` scroll the newly selected range into view.
+
+## 0.19.5 (2021-12-16)
+
+### Breaking changes
+
+The search option `matchCase` was renamed to `caseSensitive` (the old name will continue to work until the next breaking release).
+
+### Bug fixes
+
+`openSearchPanel` will now update the search query to the current selection even if the panel was already open.
+
+### New features
+
+Client code can now pass a custom search panel creation function in the search configuration.
+
+The `getSearchQuery` function and `setSearchQuery` effect can now be used to inspect or change the current search query.
+
+## 0.19.4 (2021-12-02)
+
+### Bug fixes
+
+The search panel will no longer show the replace interface when the editor is read-only.
+
+## 0.19.3 (2021-11-22)
+
+### Bug fixes
+
+Add `userEvent` annotations to search and replace transactions.
+
+Make sure the editor handles keys bound to `findNext`/`findPrevious` even when there are no matches, to avoid the browser's search interrupting users.
+
+### New features
+
+Add a `Symbol.iterator` property to the cursor types, so that they can be used with `for`/`of`.
+
+## 0.19.2 (2021-09-16)
+
+### Bug fixes
+
+`selectNextOccurrence` will now only select partial words if the current main selection hold a partial word.
+
+Explicitly set the button's type to prevent the browser from submitting forms wrapped around the editor.
+
+## 0.19.1 (2021-09-06)
+
+### Bug fixes
+
+Make `highlightSelectionMatches` not produce overlapping decorations, since those tend to just get unreadable.
+
+Make sure any existing search text is selected when opening the search panel. Add search config option to not match case when search panel is opened (#4)
+
+### New features
+
+The `searchConfig` function now takes a `matchCase` option that controls whether the search panel starts in case-sensitive mode.
+
+## 0.19.0 (2021-08-11)
+
+### Bug fixes
+
+Make sure to prevent the native Mod-d behavior so that the editor doesn't lose focus after selecting past the last occurrence.
+
+## 0.18.4 (2021-05-27)
+
+### New features
+
+Initialize the search query to the current selection, when there is one, when opening the search dialog.
+
+Add a `searchConfig` function, supporting an option to put the search panel at the top of the editor.
+
+## 0.18.3 (2021-05-18)
+
+### Bug fixes
+
+Fix a bug where the first search command in a new editor wouldn't properly open the panel.
+
+### New features
+
+New command `selectNextOccurrence` that selects the next occurrence of the selected word (bound to Mod-d in the search keymap).
+
+## 0.18.2 (2021-03-19)
+
+### Bug fixes
+
+The search interface and cursor will no longer include overlapping matches (aligning with what all other editors are doing).
+
+### New features
+
+The package now exports a `RegExpCursor` which is a search cursor that matches regular expression patterns.
+
+The search/replace interface now allows the user to use regular expressions.
+
+The `SearchCursor` class now has a `nextOverlapping` method that includes matches that start inside the previous match.
+
+Basic backslash escapes (\n, \r, \t, and \\) are now accepted in string search patterns in the UI.
+
+## 0.18.1 (2021-03-15)
+
+### Bug fixes
+
+Fix an issue where entering an invalid input in the goto-line dialog would submit a form and reload the page.
+
+## 0.18.0 (2021-03-03)
+
+### Breaking changes
+
+Update dependencies to 0.18.
+
+## 0.17.1 (2021-01-06)

+## 6.0.0 (2022-06-08)
+
+### New features
+
+The new static `EditorView.findFromDOM` method can be used to retrieve an editor instance from its DOM structure.
+
+Instead of passing a constructed state to the `EditorView` constructor, it is now also possible to inline the configuration options to the state in the view config object.
+
+## 0.20.7 (2022-05-30)
+
+### Bug fixes
+
+Fix an issue on Chrome Android where the DOM could fail to display the actual document after backspace.
+
+Avoid an issue on Chrome Android where DOM changes were sometimes inappropriately replace by a backspace key effect due to spurious beforeinput events.
+
+Fix a problem where the content element's width didn't cover the width of the actual content.
+
+Work around a bug in Chrome 102 which caused wheel scrolling of the editor to be interrupted every few lines.
+
+## 0.20.6 (2022-05-20)
+
+### Bug fixes
+
+Make sure the editor re-measures itself when its attributes are updated.
+
+## 0.20.5 (2022-05-18)
+
+### Bug fixes
+
+Fix an issue where gutter elements without any markers in them would not get the `cm-gutterElement` class assigned.
+
+Fix an issue where DOM event handlers registered by plugins were retained indefinitely, even after the editor was reconfigured.
+
+## 0.20.4 (2022-05-03)
+
+### Bug fixes
+
+Prevent Mac-style behavior of inserting a period when the user inserts two spaces.
+
+Fix an issue where the editor would sometimes not restore the DOM selection when refocused with a selection identical to the one it held when it lost focus.
+
+## 0.20.3 (2022-04-27)
+
+### Bug fixes
+
+Fix a bug where the input handling could crash on repeated (or held) backspace presses on Chrome Android.
+
+## 0.20.2 (2022-04-22)
+
+### New features
+
+The new `hideOn` option to `hoverTooltip` allows more fine-grained control over when the tooltip should hide.
+
+## 0.20.1 (2022-04-20)
+
+### Bug fixes
+
+Remove debug statements that accidentally made it into 0.20.0.
+

+
+## 0.20.0 (2022-04-20)
+
+### Breaking changes
+
+The deprecated interfaces `blockAtHeight`, `visualLineAtHeight`, `viewportLines`, `visualLineAt`, `scrollPosIntoView`, `scrollTo`, and `centerOn` were removed from the library.
+
+All decorations are now provided through `EditorView.decorations`, and are part of a single precedence ordering. Decoration sources that need access to the view are provided as functions.
+
+Atomic ranges are now specified through a facet (`EditorView.atomicRanges`).
+
+Scroll margins are now specified through a facet (`EditorView.scrollMargins`).
+
+Plugin fields no longer exist in the library (and are replaced by facets holding function values).
+
+This package no longer re-exports the Range type from @codemirror/state.
+
+### Bug fixes
+
+Fix a bug where zero-length block widgets could cause `viewportLineBlocks` to contain overlapping ranges.
+
+### New features
+
+The new `perLineTextDirection` facet configures whether the editor reads text direction per line, or uses a single direction for the entire editor. `EditorView.textDirectionAt` returns the direction around a given position.
+
+`rectangularSelection` and `crosshairCursor` from @codemirror/rectangular-selection were merged into this package.
+
+This package now exports the tooltip functionality that used to live in @codemirror/tooltip.
+

+
+The exports from the old @codemirror/gutter package are now available from this package.
+
+## 0.19.48 (2022-03-30)
+
+### Bug fixes
+
+Fix an issue where DOM syncing could crash when a DOM node was moved from a parent to a child node (via widgets reusing existing nodes).
+
+To avoid interfering with things like a vim mode too much, the editor will now only activate the tab-to-move-focus escape hatch after an escape press that wasn't handled by an event handler.
+
+Make sure the view measures itself before the page is printed.
+
+Tweak types of view plugin defining functions to avoid TypeScript errors when the plugin value doesn't have any of the interface's properties.
+
+## 0.19.47 (2022-03-08)
+
+### Bug fixes
+
+Fix an issue where block widgets at the start of the viewport could break height computations.
+
+## 0.19.46 (2022-03-03)
+
+### Bug fixes
+
+Fix a bug where block widgets on the edges of viewports could cause the positioning of content to misalign with the gutter and height computations.
+
+Improve cursor height next to widgets.
+
+Fix a bug where mapping positions to screen coordinates could return incorred coordinates during composition.
+
+## 0.19.45 (2022-02-23)
+
+### Bug fixes
+
+Fix an issue where the library failed to call `WidgetType.destroy` on the old widget when replacing a widget with a different widget of the same type.
+
+Fix an issue where the editor would compute DOM positions inside composition contexts incorrectly in some cases, causing the selection to be put in the wrong place and needlessly interrupting compositions.
+
+Fix leaking of resize event handlers.
+
+## 0.19.44 (2022-02-17)
+
+### Bug fixes
+
+Fix a crash that occasionally occurred when drag-selecting in a way that scrolled the editor.
+
+### New features
+
+The new `EditorView.compositionStarted` property indicates whether a composition is starting.
+
+## 0.19.43 (2022-02-16)
+
+### Bug fixes
+
+Fix several issues where editing or composition went wrong due to our zero-width space kludge characters ending up in unexpected places.
+
+Make sure the editor re-measures its dimensions whenever its theme changes.
+
+Fix an issue where some keys on Android phones could leave the editor DOM unsynced with the actual document.
+
+## 0.19.42 (2022-02-05)
+
+### Bug fixes
+
+Fix a regression in cursor position determination after making an edit next to a widget.
+
+## 0.19.41 (2022-02-04)
+
+### Bug fixes
+
+Fix an issue where the editor's view of its content height could go out of sync with the DOM when a line-wrapping editor had its width changed, causing wrapping to change.
+
+Fix a bug that caused the editor to draw way too much content when scrolling to a position in an editor (much) taller than the window.
+
+Report an error when a replace decoration from a plugin crosses a line break, rather than silently ignoring it.
+
+Fix an issue where reading DOM changes was broken when `lineSeparator` contained more than one character.
+
+Make ordering of replace and mark decorations with the same extent and inclusivness more predictable by giving replace decorations precedence.
+
+Fix a bug where, on Chrome, replacement across line boundaries and next to widgets could cause bogus zero-width characters to appear in the content.
+
+## 0.19.40 (2022-01-19)
+
+### Bug fixes
+
+Make composition input properly appear at secondary cursors (except when those are in the DOM node with the composition, in which case the browser won't allow us to intervene without aborting the composition).
+
+Fix a bug that cause the editor to get confused about which content was visible after scrolling something into view.
+
+Fix a bug where the dummy elements rendered around widgets could end up in a separate set of wrapping marks, and thus become visible.
+
+`EditorView.moveVertically` now preserves the `assoc` property of the input range.
+
+Get rid of gaps between selection elements drawn by `drawSelection`.
+
+Fix an issue where replacing text next to a widget might leak bogus zero-width spaces into the document.
+
+Avoid browser selection mishandling when a focused view has `setState` called by eagerly refocusing it.
+

+
+### Bug fixes
+
+Make sure the editor signals a `geometryChanged` update when its width changes.
+
+### New features
+
+`EditorView.darkTheme` can now be queried to figure out whether the editor is using a dark theme.
+
+## 0.19.38 (2022-01-05)
+
+### Bug fixes
+
+Fix a bug that caused line decorations with a `class` property to suppress all other line decorations for that line.
+
+Fix a bug that caused scroll effects to be corrupted when further updates came in before they were applied.
+
+Fix an issue where, depending on which way a floating point rounding error fell, `posAtCoords` (and thus vertical cursor motion) for positions outside of the vertical range of the document might or might not return the start/end of the document.
+
+## 0.19.37 (2021-12-22)
+
+### Bug fixes
+
+Fix regression where plugin replacing decorations that span to the end of the line are ignored.
+
+## 0.19.36 (2021-12-22)
+
+### Bug fixes
+
+Fix a crash in `posAtCoords` when the position lies in a block widget that is rendered but scrolled out of view.
+
+Adding block decorations from a plugin now raises an error. Replacing decorations that cross lines are ignored, when provided by a plugin.
+
+Fix inverted interpretation of the `precise` argument to `posAtCoords`.
+
+## 0.19.35 (2021-12-20)
+
+### Bug fixes
+
+The editor will now handle double-taps as if they are double-clicks, rather than letting the browser's native behavior happen (because the latter often does the wrong thing).
+
+Fix an issue where backspacing out a selection on Chrome Android would sometimes only delete the last character due to event order issues.
+
+`posAtCoords`, without second argument, will no longer return null for positions below or above the document.
+
+## 0.19.34 (2021-12-17)
+
+### Bug fixes

+`EditorView.scrollTo` and `EditorView.centerOn` are deprecated in favor of `EditorView.scrollIntoView`, and will be removed in the next breaking release.
+
+### Bug fixes
+
+Fix an issue that could cause the editor to unnecessarily interfere with composition (especially visible on macOS Chrome).
+
+A composition started with multiple lines selected will no longer be interruptd by the editor.
+
+### New features
+
+The new `EditorView.scrollIntoView` function allows you to do more fine-grained scrolling.
+
+## 0.19.32 (2021-12-15)
+
+### Bug fixes
+
+Fix a bug where CodeMirror's own event handers would run even after a user-supplied handler called `preventDefault` on an event.
+
+Properly draw selections when negative text-indent is used for soft wrapping.
+
+Fix an issue where `viewportLineBlocks` could hold inaccurate height information when the vertical scaling changed.
+
+Fixes drop cursor positioning when the document is scrolled. Force a content measure when the editor comes into view
+
+Fix a bug that could cause the editor to not measure its layout the first time it came into view.
+
+## 0.19.31 (2021-12-13)
+
+### New features
+
+The package now exports a `dropCursor` extension that draws a cursor at the current drop position when dragging content over the editor.
+
+## 0.19.30 (2021-12-13)
+
+### Bug fixes
+
+Refine Android key event handling to work properly in a GBoard corner case where pressing Enter fires a bunch of spurious deleteContentBackward events.
+
+Fix a crash in `drawSelection` for some kinds of selections.
+
+Prevent a possibility where some content updates causes duplicate text to remain in DOM.
+
+### New features
+
+Support a `maxLength` option to `MatchDecorator` that allows user code to control how far it scans into hidden parts of viewport lines.
+
+## 0.19.29 (2021-12-09)
+
+### Bug fixes
+
+Fix a bug that could cause out-of-view editors to get a nonsensical viewport and fail to scroll into view when asked to.
+
+Fix a bug where  would return 0 when clicking below the content if the last line was replaced with a block widget decoration.
+
+Fix an issue where clicking at the position of the previous cursor in a blurred editor would cause the selection to reset to the start of the document.
+
+Fix an issue where composition could be interrupted if the browser created a new node inside a mark decoration node.
+
+## 0.19.28 (2021-12-08)
+
+### Bug fixes
+
+Fix an issue where pressing Enter on Chrome Android during composition did not fire key handlers for Enter.
+
+Avoid a Chrome bug where the virtual keyboard closes when pressing backspace after a widget.
+
+Fix an issue where the editor could show a horizontal scroll bar even after all lines that caused it had been deleted or changed.
+
+## 0.19.27 (2021-12-06)
+
+### Bug fixes
+
+Fix a bug that could cause `EditorView.plugin` to inappropriately return `null` during plugin initialization.
+
+Fix a bug where a block widget without `estimatedHeight` at the end of the document could fail to be drawn
+
+## 0.19.26 (2021-12-03)
+
+### New features
+
+Widgets can now define a `destroy` method that is called when they are removed from the view.
+
+## 0.19.25 (2021-12-02)
+
+### Bug fixes
+
+Widgets around replaced ranges are now visible when their side does not point towards the replaced range.
+
+A replaced line with a line decoration no longer creates an extra empty line block in the editor.
+
+The `scrollPastEnd` extension will now over-reserve space at the bottom of the editor on startup, to prevent restored scroll positions from being clipped.
+
+### New features
+
+`EditorView.editorAttributes` and `contentAttributes` may now hold functions that produce the attributes.
+
+## 0.19.24 (2021-12-01)
+
+### Bug fixes
+
+Fix a bug where `lineBlockAt`, for queries inside the viewport, would always return the first line in the viewport.
+
+## 0.19.23 (2021-11-30)
+
+### Bug fixes
+
+Fix an issue where after some kinds of changes, `EditorView.viewportLineBlocks` held an out-of-date set of blocks.
+
+### New features
+
+Export `EditorView.documentPadding`, with information about the vertical padding of the document.
+
+## 0.19.22 (2021-11-30)
+
+### Bug fixes
+
+Fix an issue where editors with large vertical padding (for example via `scrollPastEnd`) could sometimes lose their scroll position on Chrome.
+
+Avoid some unnecessary DOM measuring work by more carefully checking whether it is needed.
+
+### New features
+
+The new `elementAtHeight`, `lineBlockAtHeight`, and `lineBlockAt` methods provide a simpler and more efficient replacement for the (now deprecated) `blockAtHeight`, `visualLineAtHeight`, and `visualLineAt` methods.
+
+The editor view now exports a `documentTop` getter that gives you the vertical position of the top of the document. All height info is queried and reported relative to this top.
+
+The editor view's new `viewportLineBlocks` property provides an array of in-viewport line blocks, and replaces the (now deprecated) `viewportLines` method.
+
+## 0.19.21 (2021-11-26)
+
+### Bug fixes
+
+Fix a problem where the DOM update would unnecessarily trigger browser relayouts.
+
+## 0.19.20 (2021-11-19)
+
+### Bug fixes
+
+Run a measure cycle when the editor's size spontaneously changes.
+
+## 0.19.19 (2021-11-17)
+
+### Bug fixes
+
+Fix a bug that caused the precedence of `editorAttributes` and `contentAttributes` to be inverted, making lower-precedence extensions override higher-precedence ones.
+
+## 0.19.18 (2021-11-16)
+
+### Bug fixes
+
+Fix an issue where the editor wasn't aware it was line-wrapping with its own `lineWrapping` extension enabled.
+
+## 0.19.17 (2021-11-16)
+
+### Bug fixes
+
+Avoid an issue where stretches of whitespace on line wrap points could cause the cursor to be placed outside of the content.
+
+## 0.19.16 (2021-11-11)
+
+### Breaking changes
+
+Block replacement decorations now default to inclusive, because non-inclusive block decorations are rarely what you need.
+
+### Bug fixes
+

+
+Using backspace near uneditable widgets on Chrome Android should now be more reliable.

+
+Fix an occasional crash in the selection drawing extension.
+
+## 0.19.8 (2021-09-26)
+

+## 0.19.7 (2021-09-13)
+
+### Bug fixes

+
+Remove a `console.log` that slipped into the previous release.

+
+## 0.19.1 (2021-08-11)
+
+### Breaking changes
+
+The view now emits new-style user event annotations for the transactions it generates.

+
+Fix a crash when a DOM change that ended at a zero-width view element (widget) removed that element from the DOM.

+
+## 0.18.5 (2021-04-07)

+
+## 0.18.3 (2021-03-19)
+
+### Breaking changes

+## 0.18.1 (2021-03-05)
+
+### Bug fixes
+
+Fix an issue where, on iOS, some types of IME would cause the composed content to be deleted when confirming a composition.
+
+## 0.18.0 (2021-03-03)
+
+### Breaking changes
+
+The `themeClass` function and ``-style selectors in themes are no longer supported (prefixing with `cm-` should be done manually now).
+
+Themes must now use `&` (instead of an extra `$`) to target the editor wrapper element.
+
+The editor no longer adds `cm-light` or `cm-dark` classes. Targeting light or dark configurations in base themes should now be done by using a `&light` or `&dark` top-level selector.

+### Bug fixes
+
+Long words without spaces, when line-wrapping is enabled, are now properly broken.
+
+Fix the horizontal position of selections drawn by `drawSelection` in right-to-left editors with a scrollbar.
+
+## 0.17.9 (2021-02-18)
+
+### Bug fixes
+
+Fix an issue where pasting linewise at the start of a line left the cursor before the inserted content.

+## 0.17.4 (2021-01-14)
+
+### Bug fixes
+
+The `drawSelection` extension will now reuse cursor DOM nodes when the number of cursors stays the same, allowing some degree of cursor transition animation.
+
+Makes highlighted special characters styleable (``) and fix their default look in dark themes to have appropriate contrast.
+
+### New features
+
+Adds a new `MatchDecorator` helper class which can be used to easily maintain decorations on content that matches a regular expression.
+
+## 0.17.3 (2021-01-06)
+
+### New features
+
+The package now also exports a CommonJS module.

+///
+/// The argument object maps node selectors to [highlighting
+/// tags](#highlight.Tag) or arrays of tags.
+///
+/// Node selectors may hold one or more (space-separated) node paths.
+/// Such a path can be a [node name](#common.NodeType.name), or
+/// multiple node names (or `*` wildcards) separated by slash
+/// characters, as in `"Block/Declaration/VariableName"`. Such a path
+/// matches the final node but only if its direct parent nodes are the
+/// other nodes mentioned. A `*` in such a path matches any parent,
+/// but only a single level—wildcards that match multiple parents
+/// aren't supported, both for efficiency reasons and because Lezer
+/// trees make it rather hard to reason about what they would match.)
+///
+/// A path can be ended with `/...` to indicate that the tag assigned
+/// to the node should also apply to all child nodes, even if they
+/// match their own style (by default, only the innermost style is
+/// used).
+///
+/// When a path ends in `!`, as in `Attribute!`, no further matching
+/// happens for the node's child nodes, and the entire node gets the
+/// given style.
+///
+/// In this notation, node names that contain `/`, `!`, `*`, or `...`
+/// must be quoted as JSON strings.
+///
+/// For example:
+///
+/// ```javascript
+/// parser.withProps(
+///   styleTags({
+///     // Style Number and BigNumber nodes
+///     "Number BigNumber": tags.number,

+/// This function is used to add a set of tags to a language syntax

+///
+/// The argument object maps node selectors to [highlighting
+/// tags](#highlight.Tag) or arrays of tags.
+///
+/// Node selectors may hold one or more (space-separated) node paths.
+/// Such a path can be a [node name](#common.NodeType.name), or
+/// multiple node names (or `*` wildcards) separated by slash
+/// characters, as in `"Block/Declaration/VariableName"`. Such a path
+/// matches the final node but only if its direct parent nodes are the
+/// other nodes mentioned. A `*` in such a path matches any parent,
+/// but only a single level—wildcards that match multiple parents
+/// aren't supported, both for efficiency reasons and because Lezer
+/// trees make it rather hard to reason about what they would match.)
+///
+/// A path can be ended with `/...` to indicate that the tag assigned
+/// to the node should also apply to all child nodes, even if they
+/// match their own style (by default, only the innermost style is
+/// used).
+///
+/// When a path ends in `!`, as in `Attribute!`, no further matching
+/// happens for the node's child nodes, and the entire node gets the
+/// given style.
+///
+/// In this notation, node names that contain `/`, `!`, `*`, or `...`
+/// must be quoted as JSON strings.
+///
+/// For example:
+///
+/// ```javascript
+/// parser.withProps(

+///
+/// The argument object maps node selectors to [highlighting

+///
+/// Node selectors may hold one or more (space-separated) node paths.
+/// Such a path can be a [node name](#common.NodeType.name), or
+/// multiple node names (or `*` wildcards) separated by slash
+/// characters, as in `"Block/Declaration/VariableName"`. Such a path
+/// matches the final node but only if its direct parent nodes are the
+/// other nodes mentioned. A `*` in such a path matches any parent,
+/// but only a single level—wildcards that match multiple parents
+/// aren't supported, both for efficiency reasons and because Lezer
+/// trees make it rather hard to reason about what they would match.)
+///
+/// A path can be ended with `/...` to indicate that the tag assigned
+/// to the node should also apply to all child nodes, even if they
+/// match their own style (by default, only the innermost style is
+/// used).
+///
+/// When a path ends in `!`, as in `Attribute!`, no further matching
+/// happens for the node's child nodes, and the entire node gets the
+/// given style.

+/// In this notation, node names that contain `/`, `!`, `*`, or `...`
+/// must be quoted as JSON strings.

+[ [**WEBSITE**](http://lezer.codemirror.net) | [**ISSUES**](https://github.com/lezer-parser/lezer/issues) | [**FORUM**](https://discuss.codemirror.net/c/lezer) | [**CHANGELOG**](https://github.com/lezer-parser/lr/blob/master/CHANGELOG.md) ]
+
+Lezer ("reader" in Dutch, pronounced pretty much as laser) is an
+incremental GLR parser intended for use in an editor or similar
+system, which needs to keep a representation of the program current
+during changes and in the face of syntax errors.
+
+It prioritizes speed and compactness (both of parser table files and
+of syntax tree) over having a highly usable parse tree—trees nodes are
+just blobs with a start, end, tag, and set of child nodes, with no
+further labeling of child nodes or extra metadata.
+
+This package contains the run-time LR parser library. It consumes
+parsers generated by
+[@lezer/generator](https://github.com/lezer-parser/generator).
+
+The parser programming interface is documented on [the
+website](https://lezer.codemirror.net/docs/ref/#lr).
+
+The code is licensed under an MIT license.
+
+This project was hugely inspired by
+[tree-sitter](http://tree-sitter.github.io/tree-sitter/).

+# Silvermine VideoJS Chromecast Plugin
+
+[![Build Status](https://travis-ci.org/silvermine/videojs-chromecast.svg?branch=master)](https://travis-ci.org/silvermine/videojs-chromecast)
+[![Coverage Status](https://coveralls.io/repos/github/silvermine/videojs-chromecast/badge.svg?branch=master)](https://coveralls.io/github/silvermine/videojs-chromecast?branch=master)
+[![Dependency Status](https://david-dm.org/silvermine/videojs-chromecast.svg)](https://david-dm.org/silvermine/videojs-chromecast)

+
+
+## What is it?
+
+A plugin for [videojs](http://videojs.com/) versions 6+ that adds a button to the control
+bar which will cast videos to a Chromecast.
+
+
+## How do I use it?
+
+The `@silvermine/videojs-chromecast` plugin includes 3 types of assets: javascript, CSS,
+and images.
+
+You can either build the plugin locally and use the assets that are output from the build
+process directly, or you can install the plugin as an npm module, include the
+javascript and SCSS source in your project using a Common-JS module loader and SASS build
+process, and copy the images from the image source folder to your project.
+
+Note that regardless of whether you are using this plugin via the pre-built JS or as a
+module, the Chromecast framework will need to be included after the plugin. For example:
+
+```html
+<script src="https://unpkg.com/video.js@6.1.0/dist/video.js"></script>
+<script src="./dist/silvermine-videojs-chromecast.min.js"></script>
+<script type="text/javascript" src="https://www.gstatic.com/cv/js/sender/v1/cast_sender.js?loadCastFramework=1"></script>
+```
+
+### Building the plugin locally
+
+   1. Either clone this repository or install the `@silvermine/videojs-chromecast` module
+      using `npm install @silvermine/videojs-chromecast`.
+   2. Ensure that `@silvermine/videojs-chromecast`'s `devDependencies` are installed by
+      running `npm install` from within the `videojs-chromecast` folder.
+   3. Run `grunt build` to build and copy the javascript, CSS and image files to the
+      `videojs-chromecast/dist` folder.
+   4. Copy the plugin's files from the `dist` folder into your project as needed.
+   5. Ensure that the images in the `dist/images` folder are accessible at `./images/`,
+      relative to where the plugin's CSS is located. If, for example, your CSS is located
+      at `https://example.com/plugins/silvermine-videojs-chromecast.css`, then the
+      plugin's images should be located at `https://example.com/plugins/images/`.
+   6. Follow the steps in the "Configuration" section below.
+
+Note: when adding the plugin's javascript to your web page, include the
+`silvermine-videojs-chromecast.min.js` javascript file in your HTML *after* loading
+Video.js. The plugin's built javascript file expects there to be a reference to Video.js
+at `window.videojs` and will throw an error if it does not exist.
+
+### Initialization options
+
+* **`preloadWebComponents`** (default: `false`) - The Chromecast framework relies on the
+  `webcomponents.js` polyfill when a browser does not have `document.registerElement` in
+  order to create the `<google-cast-button>` custom component (which is not used by this
+  plugin).  If you are using jQuery, this polyfill must be loaded and initialized before
+  jQuery is initialized. Unfortunately, the Chromecast framework loads the
+  `webcomponents.js` polyfill via a dynamically created `<script>` tag. This causes a race
+  condition (see #17). Also, including `webcomponents.js` anywhere on the page will break
+  jQuery's fix for bubbling some events to `document` (e.g. `onchange` events for
+  `<select>`, see #21).  Setting `preloadWebComponents` to `true` will "fix" these 2
+  problems by (1) making this plugin add the `webcomponents` polyfill synchronously when
+  the polyfill is needed and (2) using the `webcomponents-lite.js` version as it does not
+  include the shadow DOM polyfills, but still provides the `registerElement` polyfill that
+  the Chromecast framework needs. If you use the `preloadWebComponents: true` option, you
+  should make sure that this plugin is loaded before jQuery. Then include the Chromecast
+  framework after this plugin as you normally would.
+
+  **Note:** There is a caveat to using the `preloadWebComponents` setting.
+  Because the Chromecast plugin uses the shadow DOM to create the
+  `<google-cast-button>` custom component, **the `<google-cast-button>` custom
+  component may partly render, but it will not be functional**. This tag is not
+  used by this plugin. However if you must use this tag elsewhere, you should
+  not use the `preloadWebComponents` flag.
+
+  tl;dr: if you use jQuery, you should use the `preloadWebComponents: true` option in
+  this plugin.
+
+#### Providing initialization options via `require()`
+
+If requiring this plugin via NPM, any desired initialization options can be supplied to
+the constructor function exported by the module. For example:
+
+```js
+require('@silvermine/videojs-chromecast')(videojs, { preloadWebComponents: true });
+```
+
+#### Providing initialization options via `<script>`
+
+If using the prebuilt JS, the initialization options can be provided via
+`window.SILVERMINE_VIDEOJS_CHROMECAST_CONFIG`. Note that these options need to be set
+before the `<script>` tag to include the plugin.
+
+```html
+<script>
+   window.SILVERMINE_VIDEOJS_CHROMECAST_CONFIG = {
+      preloadWebComponents: true,
+   };
+</script>
+<script src="path/to/silvermine-videojs-chromecast.js"></script>
+```
+
+### Configuration
+
+Once the plugin has been loaded and registered, configure it and add it to your Video.js
+player using Video.js' plugin configuration option (see the section under the heading
+"Setting up a Plugin" on [Video.js' plugin documentation page][videojs-docs].
+
+**Important: In addition to defining plugin configuration, you are required to define the
+player's `techOrder` option, setting `'chromecast'` as the first Tech in the list.** Below
+is an example of the minimum required configuration for the Chromecast plugin to function:
+
+```js
+var options;
+
+options = {
+   controls: true,
+   techOrder: [ 'chromecast', 'html5' ], // You may have more Tech, such as Flash or HLS
+   plugins: {
+      chromecast: {}
+   }
+};
+
+videojs(document.getElementById('myVideoElement'), options);
+```
+
+Please note that even if you choose not to use any of the configuration options, you must
+either provide a `chromecast` entry in the `plugins` option for Video.js to initialize the
+plugin for you:
+
+```js
+options = {
+   plugins: {
+      chromecast: {}
+   }
+};
+```
+
+or you must initialize the plugin manually:
+
+```js
+var player = videojs(document.getElementById('myVideoElement'));
+
+player.chromecast(); // initializes the Chromecast plugin
+```
+
+#### Configuration options
+
+##### Plugin configuration
+* **`plugins.chromecast.receiverAppID`** - the string ID of a custom [Chromecast receiver
+  app][cast-receiver] to use. Defaults to the [default Media Receiver ID][def-cast-id].
+* **`plugins.chromecast.addButtonToControlBar`** - a `boolean` flag that tells the plugin
+  whether or not it should automatically add the Chromecast button to the Video.js
+  player's control bar component. Defaults to `true`.
+* **`plugins.chromecast.buttonPositionIndex`** - a zero-based number specifying the index
+  of the Chromecast button among the control bar's child components (if
+  `addButtonToControlBar` is set to `true`). By default the Chromecast Button is added as
+  the last child of the control bar. A value less than 0 puts the button at the specified
+  position from the end of the control bar. Note that it's likely not all child components
+  of the control bar are visible.
+
+##### Chromecast Tech configuration
+* **`chromecast.requestTitleFn`** - a function that this plugin calls when it needs a
+  string that will be the title shown in the UI that is shown when a Chromecast session is
+  active and connected. When the this plugin calls the `requestTitleFn`, it passes it the
+  [current `source` object][player-source] and expects a string in return. If nothing is
+  returned or if this option is not defined, no title will be shown.
+* **`chromecast.requestSubtitleFn`** - a function that this plugin calls when it needs a
+  string that will be the sub-title shown in the UI that is shown when a Chromecast
+  session is active and connected. When the this plugin calls the `requestSubtitleFn`, it
+  passes it the [current `source` object][player-source] and expects a string in return.
+  If nothing is returned or if this option is not defined, no sub-title will be shown.
+* **`chromecast.requestCustomDataFn`** - a function that this plugin calls when it needs an
+  object that contains custom information necessary for a Chromecast receiver app when a
+  session is active and connected. When the this plugin calls the `requestCustomDataFn`, it
+  passes it the [current `source` object][player-source] and expects an object in return.
+  If nothing is returned or if this option is not defined, no custom data will be sent.
+  This option is intended to be used with a [custom receiver][custom-receiver] application
+  to extend its default capabilities.
+
+Here is an example configuration object that makes full use of all required and optional
+configuration:
+
+```js
+var titles, subtitles, customData, options;
+
+titles = {
+   'https://example.com/videos/video-1.mp4': 'Example Title',
+   'https://example.com/videos/video-2.mp4': 'Example Title2',
+};
+
+subtitles = {
+   'https://example.com/videos/video-1.mp4': 'Subtitle',
+   'https://example.com/videos/video-2.mp4': 'Subtitle2',
+};
+
+customData = {
+   'https://example.com/videos/video-1.mp4': { 'customColor': '#0099ee' },
+   'https://example.com/videos/video-2.mp4': { 'customColor': '#000080' },
+};
+
+options = {
+   // Must specify the 'chromecast' Tech first
+   techOrder: [ 'chromecast', 'html5' ], // Required
+   // Configuration for the Chromecast Tech
+   chromecast: {
+      requestTitleFn: function(source) { // Not required
+         return titles[source.url];
+      },
+      requestSubtitleFn: function(source) { // Not required
+         return subtitles[source.url];
+      },
+      requestCustomDataFn: function(source) { // Not required
+         return customData[source.url];
+      }
+   },
+   plugins: {
+      chromecast: {
+         receiverAppID: '1234' // Not required
+         addButtonToControlBar: false, // Defaults to true
+      },
+   }
+};
+```
+
+##### Localization
+
+The `ChromecastButton` component has one translated string: "Open Chromecast menu". The
+"Open Chromecast menu" string appears in both of the standard places for Button component
+accessibility text: inside the `.vjs-control-text` span and as the `<button>` element's
+`title` attribute.
+
+To localize the Chromecast button text, follow the steps in the
+[Video.js Languages tutorial][videojs-translation] to add an `"Open Chromecast menu"` key
+to the map of translation strings.
+
+### Using the npm module
+
+If you are using a module loader such as Browserify or Webpack, first install
+`@silvermine/videojs-chromecast` using `npm install`. Then, use
+`require('@silvermine/videojs-chromecast')` to require `@silvermine/videojs-chromecast`
+into your project's source code. `require('@silvermine/videojs-chromecast')` returns a
+function that you can use to register the plugin with videojs by passing in a reference to
+`videojs`:
+
+```js
+var videojs = require('video.js');
+
+// Initialize the Chromecast plugin
+require('@silvermine/videojs-chromecast')(videojs);
+```
+
+Then, follow the steps in the "Configuration" section above.
+
+### Using the CSS and images
+
+If you are using SCSS in your project, you can simply reference the plugin's main SCSS
+file in your project's SCSS:
+
+```scss
+@import "path/to/node_modules/@silvermine/videojs-chromecast/src/scss/videojs-chromecast";
+```
+
+Optionally, you can override the SCSS variables that contain the paths to the icon
+image files:
+
+* **`$icon-chromecast--default`** - the path to the icon image that is displayed when the
+  Chromecast button is in its normal, default state. Defaults to
+  `"images/ic_cast_white_24dp.png"`.
+* **`$icon-chromecast--hover`** - the path to the icon image that is displayed when the
+  user hovers over the Chromecast button when it is in its normal, default state. Defaults
+  to `"images/ic_cast_white_24dp.png"`.
+* **`$icon-chromecast-casting`** - the path to the icon image that is displayed when the
+  Chromecast button is in the "casting" state (when a Chromecast session is active and
+  connected). Defaults to `"images/ic_cast_connected_white_24dp.png"`.
+* **`$icon-chromecast-casting--hover`** - the path to the icon image that is displayed
+  when the user hovers over the Chromecast button when it is in the "casting" state (when
+  a Chromecast session is active and connected). Defaults to
+  `"images/ic_cast_connected_white_24dp.png"`.
+* **`$chromecast-icon-size`** - the width and height of the icon (the button and icon is a
+  square). Defaults to `12px`.
+* **`$chromecast-title-font-size`** - the font size of the title on the screen that is
+  shown while a Chromecast session is active and connected. Defaults to `22px`.
+* **`$chromecast-subtitle-font-size`** - the font size of the sub-title on the screen
+  that is shown while a Chromecast session is active and connected. Defaults to `18px`.
+* **`$chromecast-poster-width`** - the width of the poster image on the screen that that
+  is shown while a Chromecast session is active and connected. Defaults to `100px`.
+* **`$chromecast-poster-max-height`** - the maximum height of the poster image on the
+  screen that is shown while a Chromecast session is active and connected. Defaults to
+  `180px`.
+
+
+#### Images
+
+The plugin's images are located at `videojs-chromecast/src/images`. If you have
+not overridden the icon image path variables in the SCSS, then copy the images from the
+`src/images` folder to a folder that is accessible at `./images/`, relative to where the
+plugin's CSS is located. If, for example, your CSS is located at
+`https://example.com/plugins/silvermine-videojs-chromecast.css`, then the plugin's images
+should be located at `https://example.com/plugins/images/`.
+
+In addition the the `ic_cast_white_24dp.png` icon image that is used as the default icon for
+all four button states ("default", "default + hover", "casting", "casting + hover"), the `images`
+folder contains grey, black, and blue versions of the icons.
