React Compiler integration and follow-up fixes (
315ed50, 
8f1b951)
Bun now ships the upstream React Compiler as a built-in build transform, with CLI/API wiring, parser/bundler integration, and test fixtures. The follow-up fixes a bug where reactCompilerOutputMode could enable the compiler even when reactCompiler was off, making the mode behave like configuration instead of an implicit switch.
Build profiles now distinguish debug from assertions/ASAN (de73fda)
The Rust build now enables debug_assert!()/#[cfg(debug_assertions)] in release-assertions and release-asan builds, while a new bun_debug cfg keeps Debug-only conveniences out of those profiles. This also updates related runtime/build constants and type definitions so logs and debug behavior no longer leak across profiles.
Custom lint rule added for duplicate property reads (90e2bac)
A new oxlint plugin flags cases in src/js/** where the same property is read in an if condition and again in the body, helping catch double getter/Proxy hits and other avoidable repeated work. This is a quality-and-performance guardrail for Bun’s JS internals, not a user-facing feature.
BoringSSL fork upgraded upstream (46c54cd)
Bun bumps its pinned BoringSSL fork to a newer upstream merge, preserving the project’s local crypto patches. This keeps TLS/crypto current and includes the related source-list and version updates.
