What is Dovecot?
Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.
Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.
What is Krisp?
Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.
Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.

Dovecot
2.5COMMS
Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.
◆ Current state
Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.
◆ Where it's heading
Two things are being worked at once. Security is the visible half, and the volume is striking — resource-exhaustion and parser issues in IMAP THREAD, LIST and ID, a CRIME-style compression side channel, an authentication bypass through XCLIENT forwarding. The quieter half is that fixes are increasingly gated behind version declarations: the THREAD fix needs a new index format enabled only by raising dovecot_storage_version. That mechanism, introduced with 2.4.0, is now doing real work, letting operators take format changes on their own schedule.
◆ Prediction
Experimental flags for mail UTF-8 and IMAP4rev2 have carried unchanged through every 2.4 release so far; the next branch-defining move is one of those graduating to default rather than another security round.
Krisp
5.0COMMS
Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.
◆ Current state
Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.
◆ Where it's heading
The update cadence and content point at enterprise expansion: each weekly batch adds granular admin controls, API access for audit data, and new BPO visibility tools. Voice Translation language coverage is widening consistently. Deepfake risk visibility—added in the most recent batch—signals Krisp moving into a trust-and-compliance layer for AI-assisted calls, not just audio quality.
◆ Prediction
The deepfake detection work is nascent; expect it to grow into a standalone compliance dashboard. Enterprise RFPs increasingly require call-authenticity guarantees, and Krisp's audio-layer position gives it a defensible angle on that problem that CRM or WFM vendors can't replicate.
