What is Mumble?

Mumble keeps its 1.5 VoIP line in slow maintenance while the 1.6.x rewrite inches through RC testing.

Mumble is a mature open-source VoIP client. The 1.5 line is in long-tail maintenance — v1.5.915 is its fifth stable release — while the next-generation 1.6.x series sits in release-candidate testing. Cadence is slow and steady, with stable point releases landing months apart.

What is Rocket.Chat?

Rocket.Chat opens its 8.7 cycle by moving OAuth server-side and adding phishing-resistant MFA.

Rocket.Chat ships in a tight release-candidate rhythm; most RCs in this window are patch bumps of its Meteor dependency. The substantive work clusters at the edges: 8.6 laid architectural foundations (a unified presence engine with priority-based claims, ABAC attributes via Virtru, SSRF and federation-sync fixes), and 8.7.0-rc.0 now leads with a security capability — phishing-resistant multi-factor auth and a fully server-side OAuth flow.

2.5

Mumble keeps its 1.5 VoIP line in slow maintenance while the 1.6.x rewrite inches through RC testing.

◆ Current state

Mumble is a mature open-source VoIP client. The 1.5 line is in long-tail maintenance — v1.5.915 is its fifth stable release — while the next-generation 1.6.x series sits in release-candidate testing. Cadence is slow and steady, with stable point releases landing months apart.

◆ Where it's heading

Two tracks run in parallel: incremental 1.5 stable releases that fix bugs and platform quirks, and the 1.6.x RC that carries the real forward motion. A recurring friction point is platform packaging — pre-compiled macOS binaries for the 1.5 series are no longer provided, and the in-game overlay keeps getting blocked by anti-cheat systems.

◆ Prediction

Expect continued 1.5 maintenance point releases while 1.6.x works toward a stable debut; the dropped macOS binaries and overlay anti-cheat compatibility are the likeliest near-term focus.

Rocket.Chat opens its 8.7 cycle by moving OAuth server-side and adding phishing-resistant MFA.

◆ Current state

Rocket.Chat ships in a tight release-candidate rhythm; most RCs in this window are patch bumps of its Meteor dependency. The substantive work clusters at the edges: 8.6 laid architectural foundations (a unified presence engine with priority-based claims, ABAC attributes via Virtru, SSRF and federation-sync fixes), and 8.7.0-rc.0 now leads with a security capability — phishing-resistant multi-factor auth and a fully server-side OAuth flow.

◆ Where it's heading

The open-source, self-hosted chat platform is leaning into its core differentiator: enterprise security and control. Moving OAuth off the client and adding phishing-resistant MFA extends that surface directly, while the presence engine and ABAC work signal continued investment in access governance. The direction is deeper compliance-grade infrastructure, not new end-user surface.

◆ Prediction

Expect the 8.7 line to stabilize the server-side auth flow toward GA and continue hardening the presence and attribute-based access foundations begun in 8.6.
