Version 1.57.2
Released Apr 8, 2024 - 3.68 MBWorks with firefox 78.0 and later, android 113.0 and laterSee complete release notes for 1.57.2.
This is an emergency release to fix an issue causing differential updates to fail. The issue primarily affected Firefox because of uBO's use of indexedDB prior to 1.57.0. The issue did not affect full update of filter lists even though the asset viewer would show old versions of those lists (internally uBO compiles lists and would still correctly compile from lists fetched by full updater).
