Recent highlights¶

Added four new built-in themes (GitHub, GitHub Dark, Dracula, and Alucard) with precompiled color maps for fast loading without Context
Aligned Dracula and Alucard built-in themes to be fully spec-compliant with correct color and selector mappings
Renamed rememberTomorrowTheme() to rememberTomorrowLightTheme() for naming consistency across light/dark suffix theme helpers
Removed dead legacy parser code from HtmlParser.kt to shrink AAR size and improve code coverage metrics

Added scroll-state hoisting to SyntaxHighlightedCode and SyntaxHighlightedTextEditor for programmatic scroll control
Fixed Compose Preview crashes by blocking WebView initialization in @Preview composables across the editor, read-only blocks, and theme provider
Fixed HighlightResult.spanCount semantics and CSS #RRGGBBAA color parsing order
Stabilized SyntaxHighlightedTextEditor callbacks, remembered focus/scroll modifiers, and added modifier parameters to the default copy button and language badge slot helpers
Hardened CI with release builds, Maven publication smoke test, and Compose compiler report verification

Removed the deprecated treeWalk timing property entirely from HighlightTimings
Cleaned up the timings usage in HighlightEngine and internally in HtmlToAnnotatedString
Updated the sample app performance breakdown screen and timing unit tests to remove the property
Synced documentation across the guides to reflect the updated timing model

Optimized HTML-to-AnnotatedString pipeline with SAX-style single-pass parsing, eliminating intermediate tree allocations
Added substring avoidance, in-place attribute extraction, lazy entity decoding, and allocation-free numeric parsing
Benchmarks show 29-57% faster single-theme and 5-39% faster dual-theme conversions across all fixtures
Saved Jsoup baseline and SAX optimized JSON reports under resources/html-parser-benchmarks/ for regression tracking

Replaced the JVM-only Jsoup dependency with a single-pass pure-Kotlin HTML tokenizer scoped to the hljs HTML subset
Sample APK measured 128.7 KB smaller post-R8 (-5.49%); dex drops 271 classes and 2,298 methods. Four R8/ProGuard -keep rules were removed from downstream consumers
Dual-theme highlight path is 1.27×-1.97× faster on real-world Kotlin/C/Rust/Go/C#/SQL fixtures
Added real-world language test coverage with extensive token-count assertions and an opt-in JVM microbenchmark (HtmlParserBenchmark)
Prepared the codebase for Kotlin Multiplatform (KMP)
