- update to 2.1
- Incompatible Changes:
* Mouse-mode has been rewritten. There's now no longer options for:
- mouse-resize-pane
- mouse-select-pane
- mouse-select-window
- mode-mouse
Instead there is just one option: 'mouse' which turns on mouse support
entirely.
* 'default-terminal' is now a session option. Furthermore, if this is set
to 'screen-*' then emulate what screen does. If italics are wanted, this
can be set to 'tmux' but this is still new and not necessarily supported
on all platforms with older ncurses installs.
* The c0-* options for rate-limiting have been removed. Instead, a backoff
approach is used.
- Normal Changes:
* New formats:
- session_activity
- window_linked
- window_activity_format
- session_alerts
- session_last_attached
- client_pid
- pid
* 'copy-selection', 'append-selection', 'start-named-buffer' now understand
an '-x' flag to prevent it exiting copying mode.
* 'select-pane' now understands '-P' to set window/pane background colours.
* 'renumber-windows' now understands windows which are unlinked.
* 'bind' now understands multiple key tables. Allows for key-chaining.
* 'select-layout' understands '-o' to undo the last layout change.
