What is Fonoster?

Fonoster ships four releases in a day to make linking a Twilio number a single step.

Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.

What is Pixelfed?

Pixelfed 0.15.2 ships the PHP RCE patches and turns cached timelines on for everyone.

Pixelfed v0.15.2 is an urgent security update: Docker images pick up the patched PHP for this month's two remote code execution CVEs and are rebuilt with updated CAs after the eMudhra compromise. It also makes cached timelines the default, removing two experimental flags, and bundles timeline and WebFinger fixes.

Fonoster vs Pixelfed: editorial side-by-side

F6.3

Fonoster ships four releases in a day to make linking a Twilio number a single step.

◆ Current state

Fonoster went from v0.35 to v0.38.1 on October 28. The thread is Twilio: trunk provisioning for a number link is now idempotent, a Twilio number can be linked to an app or SIP agent in one API call, linking moved server-side with an API key or Auth Token (a breaking change), and the Numbers page can do it from the UI. v0.35 also lets Routr be configured through routr-one.yaml.

◆ Where it's heading

After rebuilding its SIP and media edge and defaulting to HTTPS in the 0.31 to 0.33 run, Fonoster is now working on onboarding, using Twilio as the way to bring an existing number. The release rate stays very high and breaking changes still land in minor versions.

◆ Prediction

Expect the same number-linking flow for other carriers, or more Numbers page work; the entries only cover Twilio so far.

P5.0

Pixelfed 0.15.2 ships the PHP RCE patches and turns cached timelines on for everyone.

◆ Current state

Pixelfed v0.15.2 is an urgent security update: Docker images pick up the patched PHP for this month's two remote code execution CVEs and are rebuilt with updated CAs after the eMudhra compromise. It also makes cached timelines the default, removing two experimental flags, and bundles timeline and WebFinger fixes.

◆ Where it's heading

Pixelfed has moved quickly through 0.14.5 and 0.15 with federation fixes and new APIs, and now an upstream security patch. The notes say heavy refactoring will continue toward a Nuxt-based web UI, so the near term is more churn in the front end.

◆ Prediction

Expect more 0.15.x patches for regressions from the refactor, with the Nuxt web UI as the next visible milestone.
