+### At a glance
+
+- LLVM 22 compatibility release.
+- No breaking JavaScript/TypeScript API surface changes.
+- Internal binding update for debug-info language representation.
+- Minimum supported LLVM version raised to 22.
+
+### Changed
+
+- `DIBuilder.createCompileUnit` now calls `llvm::DISourceLanguageName(lang)` instead of a raw `dwarf::SourceLanguage` cast, matching the LLVM 22 API. The JavaScript/TypeScript signature is unchanged (still accepts a number).
+- Removed the `#if LLVM_VERSION_MAJOR >= 22` / `#else` conditional in `DIBuilder.cpp`; only the LLVM 22+ code path is retained.
+- `cmake/LLVM.cmake` version-discovery loop and minimum-version guard updated to require LLVM >= 22.

 - Replace usages of `Attribute.AttrKind.NoCapture` with LLVM 21-compatible attribute construction.

+## LLVM 22 / v9.0.x
+
+LLVM 22 introduces a source-language naming API change in debug info and bumps the minimum supported version.
+
+**At a glance**
+
+- No breaking JavaScript/TypeScript API surface changes.
+- `DIBuilder.createCompileUnit` internally now uses `DISourceLanguageName()` to wrap the language code (LLVM 22 replaced the raw `dwarf::SourceLanguage` cast).
+- Minimum required LLVM version is now 22; older LLVM versions are no longer supported.
+
+**Internal changes (no JS/TS impact)**
+
+- `DIBuilder.cpp`: removed the `#if LLVM_VERSION_MAJOR >= 22` conditional; the LLVM 22+ API is now the only code path.
+- `cmake/LLVM.cmake`: the version discovery loop and the minimum-version guard now enforce LLVM >= 22.
