SiYuan
SiYuan's third 3.8.10 alpha adds a built-in Markdown editor and video looping.
A side-by-side editorial comparison of Kavita and Mumble — release velocity, themes, recent moves, and the top alternatives to consider.
Kavita overhauls its Kavita+ premium tier and integrates Hardcover for book recommendations, its most significant monetization move in three years.
Kavita v0.9.1 delivers a complete redesign of Kavita+, the platform's premium subscription layer. The Hardcover integration — adding OAuth login and recommendation support — arrived alongside Hardcover's own launch of OAuth and Vibes recommendations, with v0.9.1.4 required to enable recommendations. The 50x scanner performance improvement from v0.8.9 continues to pay dividends for large libraries.
Mumble's 1.6 reaches a second release candidate while 1.5 loses macOS binaries.
Mumble is a mature open-source VoIP client. The 1.5 line is in maintenance, and its sixth stable release, 1.5.939 in October, shipped without new macOS binaries. The 1.6 series reached its second release candidate on October 25, about eight months after the first, with unsigned macOS binaries listed as a known issue.

The Kavita+ overhaul repositions the premium tier from a metadata downloader into a connected reading ecosystem. Hardcover integration is the first external service partnership for Kavita+, suggesting the project is moving beyond a standalone reader toward a recommendation and discovery layer. The recurring pattern of epub reader and reading experience improvements reflects a platform that has matured past basic library management.
Kavita will deepen the Hardcover integration with additional recommendation signals and expand Kavita+ to include connections to other reading platforms — likely Anilist or similar — as the subscription layer evolves from metadata tools to a reading discovery platform.

Work is moving toward a 1.6 stable release, but macOS packaging is a recurring problem across both lines. Release notes are blog links, so the feed shows milestones rather than features.
A 1.6 stable release is the likely next milestone; whether macOS builds are signed by then is unclear.
