Security & Trust
- Digitally Signed Release: NetSpeedTray is now officially signed with a trusted code signing certificate.
- No More Warnings: This eliminates the "Unknown Publisher" / SmartScreen warning when downloading and installing the application.
- Guaranteed Integrity: The signature guarantees that the executable has not been tampered with since it left our build server.
- Security Patches: We have updated critical dependencies (including fonttools and pandas) to their latest secure versions to resolve reported vulnerabilities.
- Hardened Build Process: Implemented strict input sanitization in our build pipeline to prevent script injection attacks.
Localization
- Russian Language Support: Added complete professional translation for the Russian language (Русский).
- Native Locale Names: The settings menu now displays languages using their native names (Endonyms) for better accessibility.
Automation & CI/CD
- Fully Automated Pipeline: We have moved to a robust CI/CD workflow using GitHub Actions. Every release is now built, tested, and packaged in a clean, isolated environment.
- Automated Versioning: The application version is now dynamically injected from Git tags directly into the executable and installer. This ensures the "File Version" in Windows Properties always matches the release tag perfectly.
