What is Fellow?

Fellow's public changelog has been silent since 2021 — no recent direction is observable here.

The visible signal stops in spring 2021. The last few releases were calendar-extension touch-ups: action items appearing directly in the Google Calendar extension, public view-only meeting links for external attendees, and multi-calendar sync within a single Google or Office account. Nothing in this dataset reflects the past several years of Fellow's actual work.

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.

Fellow's public changelog has been silent since 2021 — no recent direction is observable here.

◆ Current state

The visible signal stops in spring 2021. The last few releases were calendar-extension touch-ups: action items appearing directly in the Google Calendar extension, public view-only meeting links for external attendees, and multi-calendar sync within a single Google or Office account. Nothing in this dataset reflects the past several years of Fellow's actual work.

◆ Where it's heading

From the entries alone, no current trajectory can be inferred — the data is years stale. Whether Fellow has shifted to AI-meeting-notes or remained focused on the original meeting-management surface is not visible here and would be guesswork to assert.

◆ Prediction

Predictions can't be grounded in this data. The most useful next step is to refresh Fellow's changelog source so that present-day moves are captured.

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.
