Rocket.Chat vs Threema: at a glance
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.
What is Threema?
Threema ships a rare app change: spam reports for any chat on Android and iOS
On 13 November Threema improved spam reporting so users can flag single and group chats as spam on all mobile platforms, a change it credits to feedback from its in-app survey feed. It is the first app-level change in this window; the rest of the feed since July is security commentary, an August DDoS incident post and two Threema Work admin features.

Rocket.Chat
6.3COMMS
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.
Threema
5.0COMMS
Threema ships a rare app change: spam reports for any chat on Android and iOS
◆ Current state
On 13 November Threema improved spam reporting so users can flag single and group chats as spam on all mobile platforms, a change it credits to feedback from its in-app survey feed. It is the first app-level change in this window; the rest of the feed since July is security commentary, an August DDoS incident post and two Threema Work admin features.
◆ Where it's heading
Product news is starting to surface in the consumer app as well as in Threema Work administration, but at a slow pace and in small steps. The editorial line stays on security and resilience, with recent posts pitching Threema as the fallback channel during cyberattacks.
◆ Prediction
Expect further small, feedback-driven app changes alongside security commentary; the entries do not show when the larger items teased in July's roadmap post will ship.
