+## [0.2.0](https://github.com/deimonn/code-re2c/compare/v0.1.3...v0.2.0) - 2024-12-02
+
+### Added
+
+- Support for D, Haskell, Java, JavaScript, OCaml, Python, V and Zig
+- Language detection for `.re` files; now instead of relying on the `files.associations` setting, the language of a file named like `lexer.re` will be inferred based on the contents of its first line (see the [README.md](README.md))
+- Highlighting for the new `/*!svars:re2c ... */` and `/*!mvars:re2c ... */` blocks
+- New `ignore` setting to determine files that the extension should ignore
+- New `detect` setting to determine files for which the extension should infer their language
+
+### Changed
+
+- Extension now starts up with VSCode rather than when a supported language is detected; this is necessary since re2c 4.0 can work with potentially any language
+- Touched up the extension description and logo a bit
+
+### Removed
+
+- The default associations created by this extension have been removed
+
