After twenty-one months of silence, FreeSWITCH 1.11 deleted thirty legacy modules and moved on

voiptelephonylegacy-removaltlsbreaking-changes
◆Current state
The 1.11 line arrived in May 2026 after the 1.10 series had gone quiet since August 2024. Its opening release migrated to PCRE2, upgraded Windows to OpenSSL 3.x, added Debian 13 support and removed roughly thirty legacy modules. The follow-up three weeks later added a reloadcert API for hot TLS certificate reloads across mod_sofia and mod_verto without dropping calls, plus SIP 603 detection and passthrough control.
◆Where it's heading
The 1.11 releases read as deferred maintenance being paid down in one move: regex library, TLS stack, supported distributions and dead module surface all changed together after a long gap. The reloadcert work points at the same audience — operators who cannot take an outage to rotate a certificate. This is consolidation for long-running production switches, not feature expansion.
◆Prediction
Expect further 1.11.x releases continuing the security-and-stability framing, with attention on modules affected by the PCRE2 and OpenSSL 3 migrations as deployments upgrade.

◆Recent moves

    Hot TLS certificate reloads and SIP 603 passthrough

    Adds a reloadcert API that swaps TLS certificates across mod_sofia and mod_verto without disconnecting calls, alongside SIP 603+ detection and critical security fixes. It targets the same operators the 1.11.0 cleanup was aimed at.
