New: - iCloud Sync for patterns, folders, favorites, history, tutorial progress, and game stats with status card, manual “Sync Now,” auto-sync, cellular, and notification toggles. - Regex flavor picker adds NSRegularExpression, JavaScript/ECMAScript, Python, and PCRE2 alongside Swift so saved patterns keep the right engine. - Generate and share code snippets for Swift, JavaScript, Python, Java, C#, and Ruby from the pattern tools and library. - Share or open patterns via regexpress:// deep links (pattern, sample text, and flavor) directly from the library export sheet. - New Spanish and Brazilian Portuguese localizations with an in-app language selector. - Rich regex explanation sheet replaces the old alert with summaries, warnings, token breakdowns, AST view, and examples. Improvements: - Catastrophic backtracking guard warns before running risky patterns and offers fix guidance or Pro-only auto-fix hints. - Debug view now charts execution timelines and slow-token heatmaps for clearer performance diagnostics. - Debounced validation, precompile, and optimization tasks are now cancellable, avoiding stale runs and keeping editing responsive. Bug Fixes: - Pattern and folder lists refresh from persistent storage before reads, reducing stale entries after edits or sync. - Cancelled pending validation/precompile tasks when new runs start to prevent outdated errors or highlights from appearing.
