What is Gromox?
Gromox is filling in Exchange Web Services fast enough to matter for non-Outlook clients.
Gromox ships a minor roughly every four to eight weeks and has moved from 3.0 to 3.9 in this window. The centre of gravity is EWS: 3.6 landed roughly two dozen operations at once — task CRUD, delegate management, calendar occurrences with timezones, full meeting invitation and cancellation lifecycle, read receipts — and every release since has extended or corrected it. Alongside that, 3.8 introduced a per-store split-process model for the Information Store and partial IMAP4rev2 support, and 3.9 made auto-accepted room bookings send confirmations and handle cancellations.
What is Krisp?
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.

Gromox
2.5COMMS
Gromox is filling in Exchange Web Services fast enough to matter for non-Outlook clients.
◆ Current state
Gromox ships a minor roughly every four to eight weeks and has moved from 3.0 to 3.9 in this window. The centre of gravity is EWS: 3.6 landed roughly two dozen operations at once — task CRUD, delegate management, calendar occurrences with timezones, full meeting invitation and cancellation lifecycle, read receipts — and every release since has extended or corrected it. Alongside that, 3.8 introduced a per-store split-process model for the Information Store and partial IMAP4rev2 support, and 3.9 made auto-accepted room bookings send confirmations and handle cancellations.
◆ Where it's heading
The project is working outward from MAPI compatibility toward the protocols that non-Outlook clients actually speak. EWS is the clearest case, but the same pattern shows in IMAP (custom keywords, IMAP4rev2 commands, SENT* keywords fixed to test the Date header as the spec requires) and in AutoDiscover fixes that unblocked Thunderbird. A second, quieter thread is offloading format conversion to external tools — Pandoc for HTML/RTF, Chawan for HTML-to-text — rather than maintaining converters in-tree. Meeting and calendar handling generates the most fix traffic, which is what you would expect from the hardest part of an Exchange-compatible server.
◆ Prediction
Expect EWS coverage to keep expanding toward whatever operations remain unimplemented, since that has been the consistent destination of feature work for five releases. The split-process Information Store introduced in 3.8 is the other thread to watch — a config bitmask suggests further isolation work is planned rather than finished.
Krisp
6.3COMMS
Every release now serves the contact center: translation, accent, fraud, analytics.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
