Every release now serves the contact center: translation, accent, fraud, analytics.
Krisp ships everything under one banner - Call Center AI - and all ten recent releases extend it. Four feature lines are in play: Voice Translation, Accent Conversion, Voice Security (deepfake detection and agent voice verification), and Speech Analytics. The most recent work has shifted from launching those lines to giving admins control over them: translated speech speed, Spell behavior, language management, access and audit controls. Cadence is steady, alternating desktop app builds (2.78 through 2.80) with roughly biweekly web update digests.
An edge MQTT broker hardening for vehicles — and dropping the old embedded arches to do it.
NanoMQ closed out the 0.24 line and moved to 0.25 over roughly five months, shipping through a string of pre-releases before 0.25.3 became the first official 0.25 build. The work splits between memory-safety hardening — fuzzing via OSS-Fuzz and ClusterFuzz is now routine after the maintainer noted production use in robotics and vehicles — and protocol-layer restructuring, with QoS acknowledgement handling moved out of the transport layer and configuration reloading rebuilt lock-free. Release notes are candid to a fault: the maintainer publishes AI-drafted changelogs with attribution and openly says he hasn't made up his mind about the SipHash change.

The center of gravity is moving from agent-facing voice processing toward admin- and buyer-facing oversight. The Enterprise Analytics Portal and agent screen recording point at BPOs, whose own clients want visibility into the teams they contract. Accent Conversion has widened from the agent to both sides of the call, and Voice Security moved from launch into the paid trial. The repeating pattern across this window is: ship a line, then package it and instrument it.
Expect the next releases to keep filling in the administrative layer around Voice Security and Speech Analytics - retention windows, audit controls, and eventually the same externally-shareable portal treatment for security data that analytics just received.

The project is trading breadth of hardware support for depth of correctness. 0.25.5 drops official MIPS and ARMel binaries because the build toolchain and MsQuic dependency moved on, while the same release adds hazard-pointer reclamation for hot config reload — a broker chasing safety-critical deployments rather than the widest possible router install base. Bridging is the other consistent thread: nng_bridge, then a nolocal parameter for bridge clients, then the earlier anti-loop work.
Expect the 0.25 line to keep tightening QoS and session persistence, and a decision on whether SipHash client ID hashing stays given its CPU cost. Whether dropped architectures return through community builds is not addressed in these entries.
