What's new

Pane.set_title() (#​636)

New {meth}~libtmux.Pane.set_title method wraps select-pane -T, and
{attr}~libtmux.Pane.title provides a short alias for
{attr}~libtmux.Pane.pane_title:

pane.set_title("my-worker")
pane.pane_title

# 'my-worker'
pane.title

# 'my-worker'

The pane_title format variable is now included in libtmux's format queries
(it was previously excluded).

Configurable tmux binary path (#​636)

{class}~libtmux.Server now accepts a tmux_bin parameter to use an
alternative tmux binary (e.g. wemux, byobu, or a custom build):

server = Server(socket_name="myserver", tmux_bin="/usr/local/bin/tmux-next")

The path is threaded through {meth}~libtmux.Server.cmd,
{meth}~libtmux.Server.raise_if_dead, {func}~libtmux.neo.fetch_objs,
all version-check functions ({func}~libtmux.common.has_version,
{func}~libtmux.common.has_gte_version, etc.), and hook scope guards in
{class}~libtmux.hooks.HooksMixin. All child objects (Session, Window,
Pane) inherit it automatically.
Falls back to shutil.which("tmux") at execution time when not set.

Pre-execution command logging (#​636)

{class}~libtmux.common.tmux_cmd now logs the full command line at
DEBUG level before execution, complementing the existing post-execution
stdout logging. This enables diagnostic output and is a prerequisite for a
future dry-run mode.

Bug fixes

TmuxCommandNotFound raised for invalid tmux_bin path (#​636)

Previously, passing a non-existent binary path raised a raw
FileNotFoundError from subprocess. It now raises
{exc}~libtmux.exc.TmuxCommandNotFound consistently, in both
tmux_cmd and raise_if_dead.

What's new

Structured lifecycle logging across Server, Session, Window, and Pane (#​637)

All lifecycle operations (create, kill, rename, split) now emit INFO-level log
records with structured extra context. Every log call includes scalar keys
such as tmux_subcommand, tmux_session, tmux_window, tmux_pane, and
tmux_target for filtering in log aggregators and test assertions via
caplog.records.

• Add NullHandler to library __init__.py per Python logging best practices
• Add DEBUG-level structured logs for tmux_cmd execution with isEnabledFor guards
• Replace f-string log formatting with lazy %s formatting throughout
• Replace traceback.print_stack() calls with proper logger.debug(exc_info=True)
• Replace logger.exception() in options parsing with logger.warning() and tmux_option_key context
• Remove unused logger definitions from modules that don't log

Bug fixes

Window.rename_window() now raises on failure instead of silently swallowing (#​637)

Previously rename_window() caught all exceptions and logged them, masking
tmux errors. It now propagates the error, consistent with all other command
methods.

Server.kill() captures stderr and handles "no server running" gracefully (#​637)

Server.kill() previously discarded the tmux return value. It now checks
stderr, raises on unexpected errors, and silently returns for expected
conditions ("no server running", "error connecting to").

Server.new_session() checks kill-session stderr (#​637)

When kill_session=True and the existing session kill fails, new_session()
now raises LibTmuxException with the stderr instead of proceeding silently.
