- substantial bit rot accrued in 4 years of non-maintenance which made Reader unusable - Reader now works reliably on public pages - or at least it _Works For Me™_ - Refactored a substantial part of the code to comply to the "current" (ha ha) Nextcloud API - Dropped Owncloud compatibility for lack of a testing installation - Dropped IE (<11) support - Dropped compatibility with older (<20) Nextcloud versions - Dropped app-specific ajax code, now handled by SettingsController - Updated dependencies where applicable
