What is FreeSWITCH?

FreeSWITCH is shipping security releases on a cadence it never used to keep.

Three releases in four months after years of near-silence. 1.11.3 is a security and stability cut that drops Debian 11 Bullseye and gates the chat API proto in mod_sofia and mod_verto; 1.11.2 brought an interface allowlist and stricter DTLS/STUN validation; 1.11.1 added hot TLS certificate reloads. The project is treating the telephony attack surface as the main work.

What is Fourwaves?

Fourwaves adds custom domain support for event websites, removing the hosted-subdomain constraint for conference organizers

Fourwaves is shipping consistent weekly improvements to its conference management platform: custom domain mapping for event websites, an auth gate before registration forms, and presentation/participant visibility parity between the mobile app and event website. The platform is also tightening workflow correctness — fixing reviewer workload counts in assignment confirmation and fixing raw markup in bio rendering.

5.0

FreeSWITCH is shipping security releases on a cadence it never used to keep.

◆ Current state

Three releases in four months after years of near-silence. 1.11.3 is a security and stability cut that drops Debian 11 Bullseye and gates the chat API proto in mod_sofia and mod_verto; 1.11.2 brought an interface allowlist and stricter DTLS/STUN validation; 1.11.1 added hot TLS certificate reloads. The project is treating the telephony attack surface as the main work.

◆ Where it's heading

1.11.0 set the terms by deleting roughly thirty legacy modules and migrating to PCRE2, and everything since has been consolidation on the narrower tree: harden what remains, drop old platforms, gate optional protocols behind explicit configuration. Operators still on 1.10 are accumulating a larger migration the longer they wait, which is the practical effect of this cadence.

◆ Prediction

Expect the pattern to hold — further point releases on 1.11 weighted to security fixes and platform drops, with new capability arriving only where it serves TLS or SIP hardening.

Fourwaves adds custom domain support for event websites, removing the hosted-subdomain constraint for conference organizers

◆ Current state

Fourwaves is shipping consistent weekly improvements to its conference management platform: custom domain mapping for event websites, an auth gate before registration forms, and presentation/participant visibility parity between the mobile app and event website. The platform is also tightening workflow correctness — fixing reviewer workload counts in assignment confirmation and fixing raw markup in bio rendering.

◆ Where it's heading

Custom domain support moves Fourwaves toward white-label territory — event organizers can now present a fully branded web presence without the hosted subdomain being visible. The sign-in gate before forms suggests the platform is building more secure, verifiable attendee flows. Together these point to a push up-market toward professional and academic conference organizers.

◆ Prediction

Following custom domains, additional white-label features such as branded emails and registration confirmations, or improvements to the abstract submission and review workflow, are the most likely next moves.
