standardagents/dmux is a tool that manages the work of multiple AI coding agents in isolated environments and in parallel, using tmux and Git worktrees. The repository history shows the latest release as v5.11.1. However, the provided information contains no description of what changed in this version, so no specific feature change can be asserted as new news.
According to the README, it creates a separate terminal pane, worktree, and branch for each task, and lets you merge results or create a GitHub PR. A worktree is a Git feature that splits the working paths of a single repository by branch, and a pane is a work area inside a tmux screen. It supports Claude Code, Codex, and OpenCode, and it is described as offering file exploration, smart merging, macOS notifications, multi-project management, and lifecycle hooks. It is released under the MIT license, and the repository's star count is 1804.
This setup is meaningful in that it provides a flow for separating the workspaces of multiple agents and collecting their results. But the provided history contains no performance figures for parallel work and no real-world usage cases, and there are no release notes for v5.11.1, so the scope of changes in this version cannot be confirmed. The feature description can therefore serve as a reference, but stability or time-saving benefits are difficult to judge from this information alone.
