Flarum vs Rocket.Chat: at a glance
What is Flarum?
Flarum's 2.0 has been in release-candidate territory for most of a year.
Flarum is an open-source forum framework whose entire recent release history is the 2.0 train — beta.8 in March, then five release candidates from April through July. The candidates ship on a three-to-six week rhythm, and most of them publish nothing beyond a pointer to the changelog file in the tag. The last releases carrying visible detail were the earlier ones, where the work was database and rendering performance plus extension-compatibility fixes.
What is Rocket.Chat?
All the substance lands in rc.0 — this cycle it's phishing-resistant MFA
Rocket.Chat publishes a release candidate per patch, and the shape is consistent: rc.0 carries the actual changes and every candidate after it is a Meteor version bump with dependency updates. In the 8.7 cycle, rc.0 introduced phishing-resistant multi-factor authentication via a server-side OAuth flow, plus a current field on DeviceManagementSession so the sessions endpoint can flag the caller's own active session. The 8.6 candidates in this window carry nothing but version bumps. Engine versions are pinned across the line at Node 22, Deno 2.3 and MongoDB 8.

Flarum's 2.0 has been in release-candidate territory for most of a year.
◆ Current state
Flarum is an open-source forum framework whose entire recent release history is the 2.0 train — beta.8 in March, then five release candidates from April through July. The candidates ship on a three-to-six week rhythm, and most of them publish nothing beyond a pointer to the changelog file in the tag. The last releases carrying visible detail were the earlier ones, where the work was database and rendering performance plus extension-compatibility fixes.
◆ Where it's heading
The substance that is visible points at making large forums viable: eliminating N+1 queries on the discussion list, adding a composite index to fix slow unread-notification counts, and caching scheduler timestamps. Those are the changes a forum makes when instances have outgrown the original query patterns. The steady RC cadence with no beta regression suggests a stabilisation grind rather than continued feature work — but the opaque release notes make the remaining scope hard to read from outside.
◆ Prediction
A 2.0 stable release is the obvious next step, though five candidates without a published scope makes the timing unclear. Watch whether rc.6 arrives on the same three-to-six week spacing or the gap widens.

All the substance lands in rc.0 — this cycle it's phishing-resistant MFA
◆ Current state
Rocket.Chat publishes a release candidate per patch, and the shape is consistent: rc.0 carries the actual changes and every candidate after it is a Meteor version bump with dependency updates. In the 8.7 cycle, rc.0 introduced phishing-resistant multi-factor authentication via a server-side OAuth flow, plus a current field on DeviceManagementSession so the sessions endpoint can flag the caller's own active session. The 8.6 candidates in this window carry nothing but version bumps. Engine versions are pinned across the line at Node 22, Deno 2.3 and MongoDB 8.
◆ Where it's heading
The work visible here is identity and session control rather than messaging features — who is authenticated, how strongly, and which device is asking. Phishing-resistant MFA and caller-session identification are both procurement concerns for the regulated and self-hosting buyers Rocket.Chat competes for, and they arrive together. The release-candidate pattern means the feed's cadence overstates activity: six entries in this window represent two substantive changes.
◆ Prediction
Expect the 8.7 line to reach general availability with the MFA flow as its headline, and further session and device-management controls to follow on the same identity track.
