v0.7.1

RMUX v0.7.1

RMUX 0.7.1 is a patch release focused on Windows attached-input correctness, protocol hardening, CLI safety, and smoother attached rendering over slower terminal links.

Highlights

• Hardened Windows attached input in Windows Terminal / ConPTY sessions.
• Improved attached mouse handling so RMUX respects mouse on/off consistently.
• Reduced unnecessary attach output churn for smoother typing over SSH and slower terminal transports.

v0.7.0

RMUX v0.7.0

RMUX 0.7.0 focuses on speed, smoother Web Share sessions, Claude teammate workflows, Windows polish, and a cleaner release pipeline.

Highlights

• Added rmux claude, a local Claude Code launcher that runs Claude with tmux teammate mode through RMUX.
• Added the tiny CLI release layout for hot detached commands, with fallback to the full RMUX helper for complex paths.
• Improved latency for common multiplexer workflows and published reproducible benchmarks for Linux, macOS, and Windows.
• Improved Web Share smoothness under scrolling, resize, and heavy output.
• Added Nix support in the installation flow, with a single-source version flake.
• Added Snap packaging work and improved release packaging metadata.
• Added Linux aarch64 release artifacts.
• Hardened Windows shell, attach, deferred startup, and SDK smoke paths.

Fixed Issues

• Fixed Windows attached input so Ctrl-C and Ctrl-D work correctly in Windows Terminal / ConPTY sessions. Resolves #56.
• Added send-keys wait support for CLI automation, including --wait, --wait-text, --wait-next-text, --wait-visible-text, and --wait-pane-exit. Resolves #57.
• Fixed compact if-shell target parsing such as -Ft= so tmux-style right-click bindings no longer fail with unexpected argument '{. }'. Resolves #58.
• Fixed interactive PowerShell pane startup so user profiles can load instead of being suppressed by -NoProfile. Resolves #59.

Performance

• Added optimized tiny CLI paths for common detached commands such as session creation, split/resize, capture, display-message, send-keys, source-file, list-sessions, and kill-server.
• Added an operational escape hatch: RMUX_DISABLE_TINY_CLI=1 forces the packaged CLI to use the full helper.
• Added public benchmark artifacts and a generated benchmark page covering Linux, macOS, and Windows.
• Improved release smoke coverage around the tiny package layout and hot command paths.

See the benchmark page for raw numbers and reproduction instructions:
https://github.com/Helvesec/rmux/blob/main/docs/benchmarks.md

Web Share

• Improved Web Share interactive scroll latency in shared browser sessions.
• Bounded session resync and render refresh pressure.
• Hardened Web Share transport and pane-frame capability negotiation.
• Reduced visual noise from terminal theme/palette discovery.
• Improved Web Share output and link presentation in plain terminals.

Claude Teammate Mode

• Added rmux claude [args].
• RMUX starts an attached local session and passes --teammate-mode tmux to Claude automatically.
• Added private tmux shim handling so Claude can drive RMUX panes through tmux-compatible commands.
• Added Windows teammate support with a private shim and Git Bash-backed teammate panes.

SDK & Automation

• Improved CLI automation primitives for agent workflows, including send-keys --wait*, wait-pane, stream-pane, and collect-pane-output.
• Continued improving the official Python SDK and TypeScript SDK integration story.
• Kept the Rust SDK and Ratatui widget aligned with the daemon protocol.

Runtime & Compatibility

• Improved tmux-compatible command parsing around short-option clusters, queued commands, source-file behavior, and target resolution.
• Improved Windows default shell behavior and pane readiness during deferred startup.
• Improved attach/session lifecycle behavior and shutdown reliability.
• Improved SDK readiness for deferred Windows panes.
• Added stronger tests for Windows console input, SDK smoke flows, compact if-shell, and tiny CLI fallback behavior.

Packaging & Release

• Added Nix install support:

  nix profile install github:Helvesec/rmux

• Added Snap packaging groundwork.

• Added Linux aarch64 release artifacts.

• Improved WinGet manifest handling and locale/schema validation.

• Improved package-manager review gates.

v0.6.1

RMUX v0.6.1

Patch release focused on upgrade recovery and wide-character terminal input.

Fixed

• Fixed stale daemon recovery after upgrading from older RMUX versions.
  rmux kill-server can now stop an old wire-v1 daemon instead of failing with:

  protocol error: unsupported RMUX wire version 1; supported range is 2..=2

  This resolves #41.

• Fixed cursor movement and deletion around Chinese / wide UTF-8 characters.
  Arrow keys, Backspace, Delete, Erase, and Insert now operate on terminal display columns instead of corrupting wide-cell state.

  This resolves #42.

Verified

• cargo install rmux --locked --version 0.6.1 installs successfully from crates.io.
• The installed binary reports rmux 0.6.1.
• A published 0.6.1 binary can create sessions, list sessions, capture pane output, and cleanly stop the daemon.

Upgrade Note

If you upgraded from an older RMUX and still have an old daemon running, install v0.6.1 and run:

rmux kill-server

Then start RMUX again normally.

• Made attached sessions much more responsive under heavy pane output and multi-pane workloads.
• Reduced Unix PTY/FD pressure in long-running attached daemons.
• Added a tmux plugin source shim for configs that source tmux-style plugin files.
• Expanded the Rust SDK with richer pane/window/session APIs, including capture-pane support.
• Added the first official Python SDK: helvesec/rmux-python, which plugs into RMUX for Python automation workflows.
• Added shell completions, manpage packaging, and stronger package-manager validation.
