The library has been rewritten in Kotlin, but it remains binary-compatible with 4.x. The intent is to support Kotlin multiplatform in the future. This is otherwise a relatively minor, bug-fix release.

Changed

• Minimum supported API level is now 14.
• Minimum supported AGP (for embedded lint checks) is now 7.0.

Fixed

• DebugTree now finds first non-library class name which prevents exceptions in optimized builds where expected stackframes may have been inlined.
• Enforce 23-character truncated tag length until API 26 per AOSP sources.
• Support Long type for date/time format arguments when validating format strings in lint checks.
• Do not report string literal concatenation in lint checks on log message.
