What is Gromox?

Gromox keeps closing the gap with Exchange one protocol surface at a time — this round it's IMAP flags and Outlook for Mac.

Gromox ships a numbered release roughly monthly, each a mix of Exchange-protocol enhancements and fixes across emsmdb, EWS, IMAP, and the store layer. Version 3.10 makes midb synchronize IMAP message flags to and from the mailbox so they survive deletion of midb.sqlite3, adds IMAP keyword support, teaches EWS the Outlook-for-Mac smart response draft types, extends FindPeople and GetUserPhoto to personal contacts, and adds a short-TTL cache for recurring user ID and group membership lookups.

What is Pixelfed?

Pixelfed 0.15.2 ships the PHP RCE patches and turns cached timelines on for everyone.

Pixelfed v0.15.2 is an urgent security update: Docker images pick up the patched PHP for this month's two remote code execution CVEs and are rebuilt with updated CAs after the eMudhra compromise. It also makes cached timelines the default, removing two experimental flags, and bundles timeline and WebFinger fixes.

Gromox vs Pixelfed: editorial side-by-side

COMMS
2.5

Gromox keeps closing the gap with Exchange one protocol surface at a time — this round it's IMAP flags and Outlook for Mac.

◆ Current state

Gromox ships a numbered release roughly monthly, each a mix of Exchange-protocol enhancements and fixes across emsmdb, EWS, IMAP, and the store layer. Version 3.10 makes midb synchronize IMAP message flags to and from the mailbox so they survive deletion of midb.sqlite3, adds IMAP keyword support, teaches EWS the Outlook-for-Mac smart response draft types, extends FindPeople and GetUserPhoto to personal contacts, and adds a short-TTL cache for recurring user ID and group membership lookups.

◆ Where it's heading

The project is methodically completing Microsoft's protocol surface rather than building an alternative one. EWS went from partial handlers in 3.2 to the full meeting, delegate, and task surface in 3.6, and now picks up client-specific dialects like Outlook for Mac's draft types. IMAP is on the same path — keywords and colour categories in 3.8, IMAP4rev2 pieces, and now flag durability. Meanwhile the store layer keeps being split and cached for operability. The audience is clearly administrators migrating off Exchange or Kopano who need existing clients to behave unchanged.

◆ Prediction

Expect IMAP4rev2 coverage to keep filling in and more client-specific EWS dialects to appear as particular Outlook builds are tested against it.

P5.0

Pixelfed 0.15.2 ships the PHP RCE patches and turns cached timelines on for everyone.

◆ Current state

Pixelfed v0.15.2 is an urgent security update: Docker images pick up the patched PHP for this month's two remote code execution CVEs and are rebuilt with updated CAs after the eMudhra compromise. It also makes cached timelines the default, removing two experimental flags, and bundles timeline and WebFinger fixes.

◆ Where it's heading

Pixelfed has moved quickly through 0.14.5 and 0.15 with federation fixes and new APIs, and now an upstream security patch. The notes say heavy refactoring will continue toward a Nuxt-based web UI, so the near term is more churn in the front end.

◆ Prediction

Expect more 0.15.x patches for regressions from the refactor, with the Nuxt web UI as the next visible milestone.
