Release Notes

v2.3.2: Miniflux 2.3.2

Compare Source

New features

• Improved full-text search

  • Search queries now use PostgreSQL's websearch_to_tsquery, allowing quoted phrases, OR operators, and negation (-term) in search expressions.

• API improvements

  • Added GET /v1/entries/ids to efficiently retrieve paginated entry IDs.
  • Added support for updating the starred status of multiple entries through PUT /v1/entries.
  • API clients can now filter entries by tags.
  • The Go client now exposes additional feed fields (description, icon, next_check_at, notification settings, no_media_player, etc.) and supports the new tag filter.

• Atom feed improvements

  • When an Atom entry id contains an HTTP URL, it is now used as the entry URL when no dedicated link is available.

Performance improvements

• Improved full-text search performance by caching compiled regular expressions used by filtering rules.
• Reduced database work when computing category statistics.
• Improved browser caching of static assets.
• Reduced template rendering overhead by precomputing static icon URLs.

Security

• Prevent username enumeration through login timing differences.
• PostgreSQL installations running in FIPS mode are now fully supported by replacing MD5 with SHA-256 for enclosure uniqueness. This change raises the minimum supported PostgreSQL version to 11.

Bug fixes

• Fixed validation of per-feed entry filter rules in the web interface.
• SOCKS proxy URLs can once again be configured for individual feeds.
• Fixed enclosure URL proxying consistency across API endpoints.
• Fixed several API handlers that incorrectly returned 404 Not Found or 400 Bad Request instead of proper server errors.
• Fixed inconsistent handling of invalid category filters in the Entries API.
• Fixed user lookup edge cases that could result in nil pointer dereferences.
• Fixed enclosure lookup to correctly scope results by user.
• Fixed the Google Reader Quick Add endpoint to honor the configured HTTP user agent.
• Fixed refresh-all keyboard shortcut (R) to correctly display the success notification.
• Fixed localization formatting issues affecting several languages.
• Fixed request builder state leaking during feed discovery.
• Improved accessibility by correcting an aria-labelledby issue.

Localization

• Updated German (de_DE) translations.
• Updated Galician (gl_ES) translations.
