 # Changelog
 
+## 3.0.0
+
+Released on 2026-03-17
+
+### Added
+
+- **theme_converter:** scaffold converter tool- **smalto_lustre_themes:** scaffold package- **theme_converter:** implement CSS theme parser and Gleam code generator- **smalto_lustre_themes:** generate 45 theme functions- **smalto_lustre_themes:** add Lustre HTML render example
+  > Add dev/lustre_html_render.gleam that demonstrates using smalto_lustre_themes
+  > to render syntax-highlighted source code to a standalone HTML file via Lustre
+  > elements and element.to_document_string. Embeds the matching CSS theme for
+  > base text color and background styling.- **tools:** add prism supported languages to fetcher- **languages:** generate grammar modules for new languages
+
+### CI
+
+- build theme_converter- smalto lustre themes workflow- gleam 1.15.0
+
+### Documentation
+
+- **smalto_lustre_themes:** add README- **smalto_lustre_themes:** add auto-generated notice and theme list to module docs- add smalto_lustre_themes to README and docs- update readme- CONTRIBUTING
+
+### Fixed
+
+- **theme_converter:** strip @media blocks, fix doc comments, add tests
+  > Strip @media blocks before CSS parsing to prevent high-contrast
+  > overrides (e.g. `color: highlight`) from leaking into token styles.
+  > Skip asterisk separator comments in extractDescription and fall back
+  > to filename-derived descriptions for themes without doc comments.
+  >
+  > Extract converter logic into src/converter.js for testability and add
+  > 49 unit tests covering all exported functions.- restore registry, update docs and examples for new languages
+  > The prism_converter tool was overwriting the registry with only the
+  > languages converted in each run. Fix the tool to always include all
+  > known languages in the registry. Regenerate the registry with all 36
+  > languages, update language counts and tables in README, docs, and
+  > smalto.gleam module doc. Add extension mappings for the 6 new languages
+  > (C#, F#, Nginx, Razor, React JSX, React TSX) to dev/cat.gleam.- escape lone curly braces in JS regex compilation
+  > JS unicode mode (`u` flag) requires `{` and `}` to be escaped when not
+  > part of valid quantifiers, unlike PCRE which treats them as literals.
+  > This caused C#/Razor grammar regexes (e.g. `with(?=\s*{)`) to silently
+  > fail to compile on the JS target, dropping keyword and class-name rules.
+
+### Miscellaneous
+
+- smalto lustre themes v 2
+
+### Testing
+
+- **smalto_lustre_themes:** add theme rendering tests- **languages:** add C# syntax highlighting snapshot- **languages:** add F# syntax highlighting snapshot- **languages:** add Nginx syntax highlighting snapshot- **languages:** add React JSX syntax highlighting snapshot- **languages:** add React TSX syntax highlighting snapshot- **languages:** add Razor syntax highlighting snapshot- fixed test for prism tool
