Mumble
Mumble's 1.6 reaches a second release candidate while 1.5 loses macOS binaries.
A side-by-side editorial comparison of CommaFeed and Kavita — release velocity, themes, recent moves, and the top alternatives to consider.
After a summer of security patches, CommaFeed 7.4 moves feed fetching to HTTP/2.
CommaFeed's 7.x line spent July and August on security fixes, one per patch release: an image-proxy SSRF, javascript: URLs filtered at parse time, local address blocking on by default, Host header injection in password recovery, and a cross-user disclosure via starring and tagging. Version 7.4.0 on October 19 turned back to fetching, with HTTP/2, more default headers so fewer servers reject it, and tighter iframe sandboxing; 7.4.1 three days later fixed entries being marked read on scroll-back and added an HTTP/2 timeout.
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.

With the security backlog cleared, releases are shifting to feed compatibility and reading behavior. The quick 7.4.1 follow-up suggests the HTTP/2 client is still settling.
Further 7.4.x patches for the HTTP/2 client are the likeliest next entries.
Kavita v0.9.1 delivers a complete redesign of Kavita+, the platform's premium subscription layer.

The 50x scanner performance improvement from v0.8.9 continues to pay dividends for large libraries.
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.
