Release v16.4.0

Improvements

• App size: the arm64 APK shrinks from 6.2 MB to 4.4 MB (−29%) by dropping the Material Components, WorkManager and AppCompat libraries and packaging only the 31 languages the app is translated into
• Ad-block engine: the native library is 77% smaller (1.1 MB → 267 KB per ABI) and regex filter rules are now matched, so lists that use them block more
• Ad-block filter lists: a freshly downloaded list takes effect immediately instead of after the next app restart, updating a list you had switched off keeps it off, and a download interrupted by the app being killed resumes on the next launch

Bug Fixes

• Bookmark dialog no longer appears as a small empty panel and then slides into place when opened
• E-ink image cache now really honours its 16 MB budget (it used to count images, not bytes) and is shared across tabs; oversized intercepted images no longer risk out-of-memory
