What is grommunio?

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

The crawled feed carries twelve release-note stubs spanning August 2021 to June 2026, each the same 134-character sentence directing readers to GitHub for the detailed logs. Version 2026.06.1 is the most recent. Nothing in the feed states what changed in any release, so the platform's current capability surface cannot be read from this source.

What is Rocket.Chat?

Rocket.Chat finishes the 8.8 calling work while the licence wall for SSO gets a date.

The 8.8 candidate line is winding down. rc.2 is a bare Meteor version bump with no user-visible change, following rc.1 which promoted Voice Call Screen Sharing to stable and turned on the in-room call interface for every call, screen sharing available or not, alongside repairs to a message list that could quietly load a whole room's history in the background. The release that still defines the line is rc.0: LDAP and SAML deprecated on non-Premium workspaces with 9.0.0 named as the cutoff, forced end-to-end encryption for new private rooms, classification banners for ABAC-managed rooms, and the apps-engine default runtime moved from Deno to Node.

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 twelve release-note stubs spanning August 2021 to June 2026, each the same 134-character sentence directing readers to GitHub for the detailed logs. Version 2026.06.1 is the most recent. Nothing in the feed states what changed in any release, so the platform's current capability surface cannot be read from this source.

◆ 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 finishes the 8.8 calling work while the licence wall for SSO gets a date.

◆ Current state

The 8.8 candidate line is winding down. rc.2 is a bare Meteor version bump with no user-visible change, following rc.1 which promoted Voice Call Screen Sharing to stable and turned on the in-room call interface for every call, screen sharing available or not, alongside repairs to a message list that could quietly load a whole room's history in the background. The release that still defines the line is rc.0: LDAP and SAML deprecated on non-Premium workspaces with 9.0.0 named as the cutoff, forced end-to-end encryption for new private rooms, classification banners for ABAC-managed rooms, and the apps-engine default runtime moved from Deno to Node.

◆ Where it's heading

Two threads run at once and point in different directions. The calling stack keeps maturing on its own — voice, then screen sharing, now a consistent in-room surface for both — which is Rocket.Chat absorbing functions its users would otherwise reach for a separate tool to get. Against that, the 9.0 licence requirement for LDAP and SAML sorts the install base: regulated and government deployments that will pay, and unlicensed self-hosted workspaces that were there for the absence of a per-seat bill. The rc train itself has settled into a familiar shape, one substantive rc.0 followed by bumps and fixes.

◆ Prediction

Expect 8.8 to go final once the message-list fixes settle, with the LDAP and SAML licence requirement, not any calling feature, as the story of 9.0. The open question is whether the Deno-to-Node runtime switch surfaces app compatibility reports before then.
