Mumble vs Double: at a glance
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 Double?
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.

Mumble
5.0COLLAB
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.
Double
8.8COLLAB
Double turns a recorded Chrome session into an agent that repeats the task.
◆ Current state
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
◆ Where it's heading
Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
◆ Prediction
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
