+# QVAC Transcription Whisper Addon v0.3.18 Release Notes
+
+This release updates the whisper.cpp integration to use the latest API and improves Windows platform support for CI/CD workflows.
+
+## Features
+
+### Enhanced Windows Platform Support
+
+The integration test workflow now includes comprehensive Windows support with PowerShell-specific configurations. This includes separate registry configuration steps for Unix and Windows platforms, ensuring proper package authentication across all environments. The workflow now uses the `ai-run-windows-gpu` runner for better GPU-accelerated testing on Windows.
+
+### Prebuild Package Renaming Support
+
+Added automatic renaming of prebuild packages from `tetherto__*` to `qvac__*` format during the package download process. This ensures consistency across all platforms and simplifies the build artifact management.
+
+## Bug Fixes
+
+### Whisper.cpp API Compatibility
+
+Updated the integration with whisper.cpp to use the new 4-parameter API for `whisper_full()`. The previous 5-parameter version that included an explicit state parameter has been deprecated. The state is now managed internally by the whisper.cpp context, simplifying the code and removing unnecessary state management overhead.
+
+Removed the obsolete `whisper_state` member variable and related initialization code, as the new whisper.cpp API handles state management automatically through the context object.
+
+## Other
+
+Updated the integration test workflow to use a specific version of `bare@1.26.0` for better build consistency. Added the `always-auth=true` configuration for npm registry authentication to improve reliability when downloading private packages.
