What is Mumble?

Mumble's 1.6 reaches a second release candidate while 1.5 loses macOS binaries.

Mumble is a mature open-source VoIP client. The 1.5 line is in maintenance, and its sixth stable release, 1.5.939 in October, shipped without new macOS binaries. The 1.6 series reached its second release candidate on October 25, about eight months after the first, with unsigned macOS binaries listed as a known issue.

What is Mattermost?

Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.

Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.

Mumble's 1.6 reaches a second release candidate while 1.5 loses macOS binaries.

◆ Current state

Mumble is a mature open-source VoIP client. The 1.5 line is in maintenance, and its sixth stable release, 1.5.939 in October, shipped without new macOS binaries. The 1.6 series reached its second release candidate on October 25, about eight months after the first, with unsigned macOS binaries listed as a known issue.

◆ Where it's heading

Work is moving toward a 1.6 stable release, but macOS packaging is a recurring problem across both lines. Release notes are blog links, so the feed shows milestones rather than features.

◆ Prediction

A 1.6 stable release is the likely next milestone; whether macOS builds are signed by then is unclear.

M6.3

Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.

◆ Current state

Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.

◆ Where it's heading

Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.

◆ Prediction

Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.
