What is grommunio?

grommunio's feed publishes release pointers only; the changes themselves live on GitHub.

The crawled feed carries release-note stubs from 2022 to 2026, each the same sentence pointing to GitHub for the detailed logs. 2026.06.2 is the newest, published at the end of September. Nothing in the feed states what changed in any release.

What is Rocket.Chat?

Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.

The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.

grommunio vs Rocket.Chat: editorial side-by-side

G0.0

grommunio's feed publishes release pointers only; the changes themselves live on GitHub.

◆ Current state

The crawled feed carries release-note stubs from 2022 to 2026, each the same sentence pointing to GitHub for the detailed logs. 2026.06.2 is the newest, published at the end of September. Nothing in the feed states what changed in any release.

◆ Where it's heading

The only signal available is cadence, and it is thin and irregular: twelve published notes across roughly five years, with 2023.11.x, 2025.01.x and 2026.06.1 as the visible markers. That is a release-notes page maintained as an index rather than a changelog. Reading direction from grommunio would require the GitHub logs these notes point at.

◆ Prediction

Expect the next entry to be another dated pointer of the same form. Whether grommunio's real release cadence matches this feed cannot be determined from what is published here.

Rocket.Chat logo6.3

Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.

◆ Current state

The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.

◆ Where it's heading

9.0 is in stabilization: each candidate is smaller than the last, and the load fixes are being carried to the LTS line rather than held for the major. Native LiveKit video is being promoted step by step, from alpha to beta and now as the named default provider option.

◆ Prediction

With rc.7 down to a handful of fixes, 9.0.0 GA is the next likely release, followed by further 8.9.x LTS patches carrying the same fixes.
