v0.3.2

[0.3.2] - 2026-06-13

Changed

• SonarQube quality issues resolved: Replaced unreachable!() in deep_clone_value for Value::Object inside containers, fixed UB in sync unlock arm, replaced 7 .expect() calls with proper error propagation, and extracted duplicate constructor helpers.
• Code duplication reduced: Overall project duplication dropped from 4.5% to 3.9%. Extracted module-level expression helpers in methods.rs, merged duplicate equality and return value arms in statements.rs, and added signature macros to compact ~40 runtime function declarations.
• Version metadata updated: All configuration files bumped from 0.3.1 to 0.3.2.

Fixed

• Segfault when running cargo test: LD_LIBRARY_PATH was checked before DT_RUNPATH, so the workspace .so was loaded instead of the cached release .so. Added -Wl,--disable-new-dtags to force DT_RPATH, which is checked before LD_LIBRARY_PATH.
• LLD linker flags: Removed -no-pie flag to fix LLD compatibility on modern Linux distributions.

v0.3.1

[0.3.1] - 2026-05-31

Changed

• Class constructor rules clarified and enforced: new is reserved for compiler-generated class constructors and cannot be user-defined in class bodies.
• Class creation guidance updated: Documentation now consistently describes class initialization as ClassName.new() followed by field assignment, or via named factory methods such as from(...) and with_<feature>(...).
• Version metadata updated: All configuration files (Cargo.toml, package.json, tree-sitter.json, README badge, PR template, VERSION) bumped from 0.3.0 to 0.3.1.
• Grammar and parser adjustments: Updated language grammar to reflect constructor rules, ensuring accurate syntax highlighting and parser diagnostics.

Fixed

• Parser diagnostic quality: Defining func new(...) in a class now reports one targeted parser error instead of cascading with a secondary Expected expression, found '}' error.
• Documentation and examples accuracy: Updated docs and examples that previously defined new or called class .new(...) with arguments so they match current language behavior.
• Stale runtime library cache: Cleared cached libmux_runtime.a that was missing newer symbols, preventing linker errors for enum-related runtime functions.

v0.3.0

Added

• Syntax highlighting support: Added TextMate and Tree-sitter grammar support with setup guidance for VSCode, Sublime Text, JetBrains, Neovim, and Helix.
• Setup documentation: New mux-website/docs/setup.md with language installation and editor configuration guides.

Changed

• Profiling decoupled: Removed built-in profiling infrastructure (mux-profiling crate) from compiler and runtime. Profiling now uses external tools (perf, Instruments, WPA) only.
• Code quality improvements: Pinned GitHub Actions versions, added --locked to cargo commands, added Cargo.lock files, refactored Python and JavaScript generators to fix SonarQube findings.

Fixed

• Code review cleanup: Removed orphaned profiling scripts, cleaned up empty scope blocks in compiler, and fixed numbered list in CONTRIBUTING.md.

v0.2.1

[0.2.1] - 2026-04-22

Changed

• Compiler maintainability work: Reduced complexity across compiler modules with a broad cleanup and refactor pass.
• Standard library internals: Refactored and optimized stdlib implementations for better consistency and maintainability.
• Developer workflow and project metadata: Updated AI agent guidance, OpenCode configuration, and supporting repository automation files.
• Documentation and website updates: Improved README content and landing page structure, examples, and installation guidance.

Fixed

• Codegen regressions: Fixed recent LLVM IR generation regressions and related import handling issues.
• Website behavior: Corrected landing page rendering details, including list key usage and stack example behavior.
• Build and CI support scripts: Fixed tooling and script issues affecting local and CI workflows.
• Versioning release prep: Synced release metadata and version-related files for 0.2.1.

Security

• Dependency and vulnerability updates: Applied dependency maintenance and vulnerability fixes, including Dependabot-driven updates.
• Static analysis cleanup: Addressed SonarCloud findings and code quality issues across the codebase.
