- Added CPU variant support for x64 native addons with modern (AVX2/x86-64-v3) and baseline (x86-64-v2) variants, enabling automatic fallback when modern variants are unavailable.
- Added automatic AVX2 CPU detection on Linux, macOS, and Windows platforms to select appropriate native addon variant at runtime.
- Updated native addon filename scheme to include CPU variant suffix (e.g., pi_natives.linux-x64-modern.node) for x64 platforms.
- Updated CLI update mechanism to support downloading and installing multiple native addon variants per platform with fallback support.
- Removed fallback untagged pi_natives.node binary creation; platform and variant-tagged binaries are now required.
- Fixed schema normalization in Google provider to handle array-valued type fields by converting them to single type with nullable flag.
- Refactored version parsing in install script to use bash parameter expansion instead of IFS field splitting.
- Changed variable declarations from let to var in theme module global scope.
- Migrated environment variable access from direct process.env to centralized getEnv() utility function across all packages.
- Renamed environment variable prefix from OMP_ to PI_ throughout codebase (e.g., OMP_CODING_AGENT_DIR -> PI_CODING_AGENT_DIR).
- Removed automatic environment variable migration from PI_ to OMP_ prefixes via migrate-env.ts module.
- Removed env setting from configuration schema and applyEnvironmentVariables() method from settings.
- Updated CI/CD build configuration to use PI_COMPILED flag instead of OMP_COMPILED.
- Changed venvPath property in PythonRuntime from nullable (string | null) to optional (string | undefined).
- Added native addon distribution and installation support to the CLI update mechanism, enabling platform-specific native modules to be downloaded and installed alongside the main binary.
- Added platform validation in native addon loader to verify supported platforms (linux-x64, linux-arm64, darwin-x64, darwin-arm64, win32-x64) with helpful error messages for unsupported configurations.
- Enhanced native addon loading error messages to provide platform-specific troubleshooting guidance for both npm/bun installations and local development environments.
- Updated installation scripts (install.sh, install.ps1) to download and install native addon files alongside the main binary during CLI installation.
- Updated minimum Bun engine requirement from 1.2.0 to 1.3.7 across root and coding-agent packages.
- Added Bun version validation to install.ps1 with Get-BunVersion, Test-BunVersion, and Assert-BunVersion functions to enforce minimum version requirement.
- Added Bun version validation to install.sh with version_ge and require_bun_version functions to enforce minimum version requirement.
- Added Windows ARM64 binary support and architecture detection in installers.
- Updated WASM loading to use streaming with base64 fallback for binary compatibility.
- Moved TTSR settings to dedicated tab and expanded abbreviation to Time Traveling Stream Rules.
- Added comprehensive install testing infrastructure with Docker validation.
- Updated package name from @oh-my-pi/omp-coding-agent to @oh-my-pi/pi-coding-agent.
- Added --ref flag to install specific tags, branches, or commits from source or binary releases.
- Enabled source installation from git refs by cloning and checking out the specified reference.
- Added git availability check for source installations with --ref flag.
- Updated README with usage examples for --ref flag on both shell and PowerShell installers.
- Renamed CLI binary and package from 'pi' to 'omp' across all platforms and installers.
- Changed environment variable prefix from PI_* to OMP_* with automatic migration support.
- Changed configuration directory from ~/.pi/ to ~/.omp/ with multi-path fallback discovery.
- Added getConfigDirPaths(), findConfigFile(), and readConfigFile() functions for config resolution across .omp, .pi, and .claude directories.
- Added --source and --binary flags to control installation method in install scripts.
- Enabled automatic bun detection with fallback to prebuilt binary for default installation.
- Added bun-based installation option that installs bun automatically if needed.
- Documented new installer options in README with usage examples.
- Added `pi update` command for checking and installing CLI updates from GitHub releases or bun.
- Added cross-platform installer scripts (shell and PowerShell) with automatic PATH configuration.
- Changed HTML export to use compile-time bundled templates via Bun macros.
- Changed `exportToHtml` and `exportFromFile` functions to async operations.
