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 Tawk.to?

tawk.to's widget 4.4.0 turns to keyboard and screen-reader fixes after a run of form work.

tawk.to is a free live chat widget that ships a version every few weeks, mostly fixes with periodic capability additions. The 4.x line added two JavaScript APIs in September and per-country phone length checks in 4.3.0. Widget 4.4.0 adds a close button inside round widgets and fixes keyboard, focus-outline and screen-reader issues, plus custom chat buttons that failed on sites asking for consent.

Fonoster vs Tawk.to: 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.

5.0

tawk.to's widget 4.4.0 turns to keyboard and screen-reader fixes after a run of form work.

◆ Current state

tawk.to is a free live chat widget that ships a version every few weeks, mostly fixes with periodic capability additions. The 4.x line added two JavaScript APIs in September and per-country phone length checks in 4.3.0. Widget 4.4.0 adds a close button inside round widgets and fixes keyboard, focus-outline and screen-reader issues, plus custom chat buttons that failed on sites asking for consent.

◆ Where it's heading

Recent work splits between developer hooks for host sites, data quality in visitor forms, and now accessibility: 4.4.0 is mostly about the widget working without a mouse. The consent-site fix continues the privacy thread from 3.6.0. Nothing in the entries points to a change of direction.

◆ Prediction

Expect more accessibility and form fixes in 4.x point releases; the entries do not show anything larger on the way.
