 #### Big news
 - Frontend, druntime and Phobos are at version [2.100.1](https://dlang.org/changelog/2.100.0.html). (#3970, #4008, #4009)
 - LLVM for prebuilt packages bumped to v14.0.3. (#3952, #3979)
   - All LLVM targets are enabled now (=> more targets for cross-compilation).
   - For the Mac package, the minimum supported macOS version has been raised to v10.12.
 - The minimum D version for bootstrapping has been raised to v2.079 (for GDC: v9.4), in line with DMD. (#3956)
 - The minimum LLVM version has been raised to v9.0. (#3960)
+- New LeakSanitizer support via `-fsanitize=leak` (not (yet?) supported on Windows). (#4005)
 - New prebuilt *universal* macOS package, runnable on both x86_64 and arm64, and enabling x86_64/arm64 macOS/iOS cross-compilation targets out of the box (`-mtriple={x86_64,arm64}-apple-{macos,ios12.0}`). The x86_64 package doesn't bundle any arm64 libs anymore; the arm64 package newly bundles iOS libs (arm64). (#3958)
+  - Avoid an external x86_64-only dub, use the bundled universal dub executable instead.
 
 #### Platform support
 - Supports LLVM 9.0 - 14.0.
 
 #### Bug fixes
+- Enable output of variable names in ASan and MSan error reporting. (#4004)
 - Report unexpected type repaints as fatal ICEs instead of crashing. (#3990, #3991)
