2026.7.0

What's Changed

This release adds multi-device reading statistics, fixes KOReader metadata and book-serving edge cases, and expands prebuilt binary support across Linux and Windows.

Reading Statistics

• Added support for merging statistics from multiple KOReader databases
• --statistics-db can now be specified multiple times, while statistics_db accepts either a single path or an array in the config file
• Databases are merged in memory using KOReader's synchronization semantics without modifying the source files
• Watch mode monitors every configured statistics database and re-merges when any of them changes
• Multiple-database merging requires KOReader 2020.10 or newer

Library and KOReader

• Fixed .fb2.zip books not finding their metadata.zip.lua sidecars
• Fixed book files becoming unavailable in serve mode when --library-path used a relative path (#94)
  • Thanks to @Niwilai for reporting and providing the original fix for the relative-path issue
• Improved Lua integer-key handling and validation across 32-bit and 64-bit targets

Platform Support

• Added GNU and static musl binaries for 32-bit x86 and ARMv7 Linux
• Windows binaries now use MSVC and are available for x86_64 and ARM64
• Linux GNU binaries support glibc 2.17, while musl binaries are statically linked
• macOS remains available as separate Intel and Apple Silicon builds; the universal archive is no longer published
• Added smoke tests, compatibility checks, checksums, provenance attestations, and signing/notarization verification for release artifacts

Internal

• Added GitHub Actions workflows for testing, linting, formatting, auditing, documentation, and cross-platform builds
• Added conventional commit-message enforcement
• Updated backend and frontend dependencies, including mlua 0.12, quick-xml 0.41, tower-http 0.7, React Router 8, and security-fixed undici releases
• Documented the release process, supported artifacts, compatibility floors, and local cross-compilation requirements
