Proton Bridge
Proton Bridge spends its first release in ten weeks on crashes, memory bounds and dead code
A side-by-side editorial comparison of Chanty and Gromox — release velocity, themes, recent moves, and the top alternatives to consider.
Chanty's feed is an HR statistics content mill, not a product changelog
Every entry in the window is a marketing article — referral, theft and satisfaction statistics roundups, plus a run of competitor-alternatives listicles published in a single batch. Nothing here describes a change to the messaging product itself.
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.

The publishing effort is going into search-driven HR and collaboration content aimed at buyers comparing team chat tools, with the alternatives posts targeting Slack, Yammer, Jive, Google Chat and Skype by name. Product direction cannot be read from this feed at all.
Expect more statistics roundups and comparison listicles; the feed gives no basis for predicting anything about the product.

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.
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.
