Krisp moves call transcripts and live captions to cloud transcription in KrispCX 2.84.4.
Krisp sells a Call Center AI suite to BPOs and contact centers: Accent Conversion, Voice Translation, QA scoring, deepfake and fraud detection. KrispCX 2.84.4 adds cloud transcription in beta for more accurate transcripts and Live Captions, plus in-call hints when the Krisp microphone is in use; the source note is truncated. October brought Conference mode for Voice Translation and a Fraud Detection beta.
Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures
Mailu's 2024.06 branch ships pinned releases, each tied to a single issue. October brought resolver fixes for the DNSSEC KSK rollover and SERVFAIL healthchecks, Roundcube 1.6.20, then PHP2Shell CVE mitigations in webmail followed by the patched PHP runtime. 2024.06.68 on 8 November carries the same PHP2Shell mitigation note again.

October brought Conference mode for Voice Translation and a Fraud Detection beta.
Releases arrive on a two-week cadence and keep stacking agent-assist features on the live call, from translation to fraud signals to captions. The September move to free-to-try has been followed by incremental depth rather than new product lines.
Expect more of the live-call layer to move to cloud processing, with QA scoring and translation likely reusing the new transcription. The truncated notes leave the scope of the cloud beta unclear.

The project remains in one-fix-per-release maintenance on the 2024.06 line, with upstream webmail and PHP security driving much of the cadence. Nothing in the entries points to a new main release.
The next releases will most likely follow upstream Roundcube or PHP security fixes, as three of the last six did.
