been a limitation for a long time.
There are two new options, window-size and default-size, and a new
command, resize-window. The force-width and force-height options and the
session_width and session_height formats have been removed.
The new window-size option tells tmux how to work out the size of
windows: largest means it picks the size of the largest session,
smallest the smallest session (similar to the old behaviour) and manual
means that it does not automatically resize windows. The default is
currently largest but this may change. aggressive-resize modifies the
choice of session for largest and smallest as it did before.
If a window is in a session attached to a client that is too small, only
part of the window is shown. tmux attempts to keep the cursor visible,
so the part of the window displayed is changed as the cursor moves (with
a small delay, to try and avoid excess redrawing when applications
redraw status lines or similar that are not currently visible). The
offset of the visible portion of the window is shown in status-right.
Drawing windows which are larger than the client is not as efficient as
those which fit, particularly when the cursor moves, so it is
recommended to avoid using this on slow machines or networks (set
window-size to smallest or manual).
The resize-window command can be used to resize a window manually. If it
is used, the window-size option is automatically set to manual for the
window (undo this with "setw -u window-size"). resize-window works in a
similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and
-A flags. -a sets the window to the size of the smallest client (what it
would be if window-size was smallest) and -A the largest.
For the same behaviour as force-width or force-height, use resize-window
-x or -y, and "setw -u window-size" to revert to automatic sizing..
If the global window-size option is set to manual, the default-size
option is used for new windows. If -x or -y is used with new-session,
that sets the default-size option for the new session.
The maximum size of a window is 10000x10000. But expect applications to
complain and much higher memory use if making a window excessively
big. The minimum size is the size required for the current layout
including borders.
The refresh-client command can be used to pan around a window, -U -D -L
-R moves up, down, left or right and -c returns to automatic cursor
tracking. The position is reset when the current window is changed.
event_reinit) - if the child gets a signal and fires the libevent signal
handler during this period it could write a signal into the parent's
signal pipe. GitHub issue 1001 from Aaron van Geffen.
instead if there is a pipe-pane active, do not exit until all data is
read (including any libevent hasn't seen yet). Fixes problem reported by
Theo Buehler and still seems to solve the original issue.
until the end of the server loop, tmux may have gone through several
internal resizes in between. This can be a problem if the final size is
the same as the initial size (what the application things it currently
is), because the application may choose not to redraw, assuming the
screen state is unchanged, when in fact tmux has thrown away parts of
the screen, assuming the application will redraw them.
To avoid this, do an extra resize if the new size is the same size as
the initial size. This should force the application to redraw when tmux
needs it to, while retaining the benefits of deferring (so we now resize
at most two times instead of at most one - and only two very rarely).
Fixes a problem with break-pane and zoomed panes reported by Michal
Mazurek.
some modern features.
Now the common code is in mode-tree.c, which provides an API used by the
three modes now separated into window-{buffer,client,tree}.c. Buffer
mode shows buffers, client mode clients and tree mode a tree of
sessions, windows and panes.
Each mode has a common set of key bindings plus a few that are specific
to the mode. Other changes are:
- each mode has a preview pane: for buffers this is the buffer content
(very useful), for others it is a preview of the pane;
- items may be sorted in different ways ('O' key);
- multiple items may be tagged and an operation applied to all of them
(for example, to delete multiple buffers at once);
- in tree mode a command may be run on the selected item (session,
window, pane) or on tagged items (key ':');
- displayed items may be filtered in tree mode by using a format (this
is used to implement find-window) (key 'f');
- the custom format (-F) for the display is no longer available;
- shortcut keys change from 0-9, a-z, A-Z which was always a bit weird
with keys used for other uses to 0-9, M-a to M-z.
Now that the code is simpler, other improvements will come later.
Primary key bindings for each mode are documented under the commands in
the man page (choose-buffer, choose-client, choose-tree).

if the pane is zoomed, so instead add a new function to just check if
the pane is actually on screen (most commands still want to accept panes
invisible by zoom). Also reject panes outside the window for various
special targets. Problem reported by Sean Haugh.
add a link of winlinks to each window and a pointer to the session to
each winlink. Also rewrite the alerts processing to return to the old
behaviour (alert in any window sets the flag on any winlink).
sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank
cells using the current background colour rather than the default
colour.
On modern systems BCE doesn't really have many benefits, but most other
terminals now support it, some (lazy) applications rely on it, and it is
not hard to include now that we have pane background colours anyway.

The vi-copy and emacs-copy mode key tables are gone, and instead copy
mode commands are bound in one of two normal key tables ("copy-mode" or
"copy-mode-vi"). Keys are bound to "send-keys -X copy-mode-command". So:
bind -temacs-copy C-Up scroll-up
bind -temacs-copy -R5 WheelUpPane scroll-up
Becomes:
bind -Tcopy-mode C-Up send -X scroll-up
bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up
This allows the full command parser and command set to be used - for
example, we can use the normal command prompt for searching, jumping,
and so on instead of a custom one:
bind -Tcopy-mode C-r command-prompt -p'search up' "send -X search-backward '%%'"
command-prompt also gets a -1 option to only require on key press, which
is needed for jumping.
The plan is to get rid of mode keys entirely, so more to come eventually.
into the read callback several times in succession; swap back when we
see empty buffers several times. This hopefully limits how much programs
that print a lot for a long period can monopolize tmux (like large, fast
compiling), without penalizing programs that print a lot briefly (like
most curses applications). Helps a lot for me, the actual numbers may
need tweaking later.
