 ## Summary
 
-Promote 4.2.0 from 4.2.0‑beta.1 with no functional changes. Stability already verified across core flows and ecosystems during beta; this release locks the artifacts, tags the repo, and rolls out broadly.
+4.2.0 graduates from beta with a handful of last‑minute polish items: Android 15 readiness (compile/target toolchains + CI installers), WalletConnect crash fixes for builds that excluded the legacy Pay module, and refreshed sr25519 native libraries that work with the new `shared_utils` package. These changes landed after the beta cut and are now part of the stable release.
 
 ## Changes Since 4.2.0‑beta.1
 
-- No functional changes; version bump only
-- Continue to monitor crash/ANR metrics and session health
+- **Android 15 readiness:** bumped `compileSdkVersion`/build tools to 36 and taught CI + local validation scripts to provision the matching SDK packages.
+- **WalletConnect stability:** added a lightweight `WalletConnectPay` stub so builds without the Pay module no longer crash during `WalletKit` init.
+- **sr25519 key generation fix:** rebuilt the Rust libraries for all ABIs so JNI exports match the current `shared_utils` namespace; account creation/import works again on fresh installs.
+- **fearless-utils composite guard:** Gradle 9 shims now only opt in automatically when the utils repo supports them, preventing configuration failures (use `FORCE_LOCAL_UTILS` to override).
+- **General build hygiene:** lint gate restored (fails on error) and dependency substitution shims keep working with the Gradle 9 wrapper.
