Compare Source

✨ New Features

• UI: Added a "Back to top" link for easier navigation.
• Integrations:
  • Added support for Wallabag tags.
  • Added support for LinkTaco service to save articles.

🐛 Bug Fixes

• API: Fixed issue where removed entries could still be returned. It was generating an error when fetching entries.
• Icons: Improved handling of relative icon URLs within subfolders.
• Timezone: Ensured only current IANA time zones are used. This avoids issues with Debian Trixie where deprecated time zones have been removed.

🛠 Refactoring & Improvements

• Complete rewrite of the config parser with validation and consistency improvements.
• Combined YouTube subscription parsing functions into a single function.
• Simplified and optimized JavaScript files (modal_handler.js, removed isTouchSupported()).
• Refactored internal code to consistently use time.Duration for time values across CLI, server, fetcher, metrics, and HTTP components.
• Replaced "Bookmarks" with "Starred" across UI and codebase for consistency.
• Template and UI cleanups: explicit template dependencies, moved inline SVGs to sprite.svg, improved layout.html consistency.
• Strengthened the JavaScript Trusted Types policy to enhance security.
• Updated translations for German, Polish, and French.

⚡ Performance

• XML Parsing: Optimized filterValidXMLChars (~4% faster).
• Sanitizer: Improved sanitization performance by ~10% using slices.Contains.
• Converted slices to arrays in some internal structures for efficiency.
