Mumble
Mumble's 1.6 reaches a second release candidate while 1.5 loses macOS binaries.
A side-by-side editorial comparison of Prowlarr and Shiori — release velocity, themes, recent moves, and the top alternatives to consider.
Prowlarr adds Trusted Networks and host validation, then moves to 2.7
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. 2.6.5 added a Trusted Networks setting and hostname validation, with follow-up fixes to Allowed Hosts logging and health checks. 2.7.0 bundled wildcard IP support in Allowed Hosts, IMDb search for BroadcasTheNet, a longer AvistaZ rate limit and base64 decoding in Cardigann definitions.
A Go bookmark manager rebuilding itself around an API — and only ever shipping release candidates.
Shiori is a self-hosted read-later and bookmark tool whose recent history is entirely release candidates: v1.7.0-rc.2, rc.3, v1.7.2-rc.1, v1.8.0-rc.1. The visible work has moved off the web UI and into an API v1 surface — tag endpoints, bookmark-tag association, filtering and counts — plus infrastructure like proxy-header authentication and SQLite performance. The last tagged release in this window is from July 2025.

Security settings that limit which hosts and networks can reach the app are the main thread since September, rolled out in step with Lidarr. Indexer definitions keep getting small compatibility fixes.
More indexer-level fixes and Allowed Hosts follow-ups are likely in 2.7 patches.
Shiori is a self-hosted read-later and bookmark tool whose recent history is entirely release candidates: v1.7.0-rc.2, rc.3, v1.7.2-rc.1, v1.8.0-rc.1.

The last tagged release in this window is from July 2025.
The project is converting from a web app with an API bolted on into an API-first service with a client, and the login component, PWA and theme work are being rewritten around that split. Proxy forward-header authentication in particular is a deployment-shape decision: it assumes Shiori sits behind an authenticating reverse proxy rather than owning identity itself. The RC-only tagging pattern makes it hard to tell what the maintainers consider stable.
The next step is presumably a final v1.8.0 consolidating the API v1 tag work, though nothing in these entries indicates the RC-to-stable promotion is scheduled. If the pattern holds, the following RC continues on API endpoints rather than the UI.
