py(deps[libtmux]) Bump 0.58.1 -> 0.59.0 (tmux 3.7 support)#1057
Merged
Conversation
why: libtmux 0.59.0 adds tmux 3.7 support and works around an upstream tmux 3.7 regression where break-pane crashed the server with a NULL-pointer dereference. Picking it up lets tmuxp run on tmux 3.7. what: - Bump libtmux ~=0.58.1 -> ~=0.59.0 in pyproject.toml - Update uv.lock to libtmux 0.59.0 from PyPI libtmux 0.59.0 (2026-06-27): - Add tmux 3.7 to the tested version matrix (3.2a-3.7) - Fix: Pane.break_pane no longer crashes the tmux 3.7 server (#693) Release: https://github.com/tmux-python/libtmux/releases/tag/v0.59.0 Changelog: https://libtmux.git-pull.com/history.html#libtmux-0-59-0-2026-06-27
why: tmux 3.7 reworded the pane-overflow error from "no space for new pane" to "size or position no space for a new pane". The issue-800 regression test pinned the old text and failed on tmux 3.7. what: - Widen the pytest.raises match to r"no space for (a )?new pane" so it matches both the pre-3.7 and 3.7 phrasings - Add a comment documenting the tmux 3.7 wording change
why: libtmux 0.59.0 adds tmux 3.7 support, so tmuxp should verify it builds and tests cleanly against the new release. what: - Add '3.7' to the tmux-version build matrix alongside 3.2a-3.6 and master in .github/workflows/tests.yml

why: Record the libtmux floor bump and tmux 3.7 support under the 1.71.0 unreleased block. The release lead paragraph and version header are added by the maintainer at tag time, not by this PR. what: - Record the libtmux ~=0.58.1 -> ~=0.59.0 floor bump under Dependencies - Note tmux 3.7 support under What's new, scoped to the user-visible change (supported version range) without CI, break-pane, or test mechanics
