CommaFeed vs Mumble: at a glance
What is CommaFeed?
CommaFeed is patching its way through the attack surface a self-hosted reader inherits
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
What is Mumble?
Mumble keeps its 1.5 VoIP line in slow maintenance while the 1.6.x rewrite inches through RC testing.
Mumble is a mature open-source VoIP client. The 1.5 line is in long-tail maintenance — v1.5.915 is its fifth stable release — while the next-generation 1.6.x series sits in release-candidate testing. Cadence is slow and steady, with stable point releases landing months apart.

◆ Current state
CommaFeed's 7.x line has become a sustained security pass. The newest patch closes Host header injection on the password recovery endpoint and adds a commafeed.password-recovery-public-base-url setting so the email base URL is configured rather than taken from the request. Behind it: local address blocking made secure by default alongside Google Reader API support in 7.3.0, javascript: URLs filtered at parse time in 7.2.1, and SSRF limits on the image proxy in 7.2.0.
◆ Where it's heading
Every release in this stretch closes a path where content or a request from outside the instance was trusted too far - feed URLs reaching internal addresses, proxied images, javascript: links, and now a header shaping an outbound email. That is the checklist of a project being run as a multi-user hosted service rather than a single-user tool, and it follows directly from the 7.0.0 decision to sandbox filter expressions. Feature work continues in parallel but is clearly the smaller half.
◆ Prediction
The remaining untrusted-input surfaces - OPML import and the feed fetcher's redirect handling - are the likely next targets. The pattern of shipping each fix as its own patch release should continue rather than batching them.
Mumble
2.5COLLAB
Mumble keeps its 1.5 VoIP line in slow maintenance while the 1.6.x rewrite inches through RC testing.
◆ Current state
Mumble is a mature open-source VoIP client. The 1.5 line is in long-tail maintenance — v1.5.915 is its fifth stable release — while the next-generation 1.6.x series sits in release-candidate testing. Cadence is slow and steady, with stable point releases landing months apart.
◆ Where it's heading
Two tracks run in parallel: incremental 1.5 stable releases that fix bugs and platform quirks, and the 1.6.x RC that carries the real forward motion. A recurring friction point is platform packaging — pre-compiled macOS binaries for the 1.5 series are no longer provided, and the in-game overlay keeps getting blocked by anti-cheat systems.
◆ Prediction
Expect continued 1.5 maintenance point releases while 1.6.x works toward a stable debut; the dropped macOS binaries and overlay anti-cheat compatibility are the likeliest near-term focus.
