multiple commands to be easily bound to one hook. set-hook and
show-hooks remain but they are now variants of set-option and
show-options. show-options now has a -H flag to show hooks (by default
they are not shown).
and the previous restored when the top is exited. If a mode that is
already on the stack is entered, the existing instance is moved to the
top as the active mode rather than being opened new.
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).

and not have to wait for an update when they change pane, we allow
commands to run more than once a second if the expanded form
changes. Unfortunately this can mean them being run far too often
(pretty much continually) when multiple clients exist, because some
formats (including #D) will always differ between clients.
To avoid this, give each client its own tree of jobs which means that
the same command will be different instances for each client - similar
to how we have the tag to separate commands for different panes.

CMD_FIND_* flags in the cmd_entry and call it for the command. Commands
with special requirements call it themselves and update the target for
hooks to use.
jobs, this means that if the same job is used for different windows or
panes (for example in pane-border-format), it will be run separately for
each pane.
but there is also now a global command queue. Instead of command queues
being dispatched on demand from wherever the command happens to be
added, they are now all dispatched from the top level server
loop. Command queues may now also include callbacks as well as commands,
and items may be inserted after the current command as well as at the end.
This all makes command queues significantly more predictable and easier
to use, and avoids the complex multiple nested command queues used by
source-file, if-shell and friends.
A mass rename of struct cmdq to a better name (cmdq_item probably) is
coming.
which could potentially free the currently running command, so we need
to take a reference to it in cmdq_continue_one.

confusing, particularly trying to automatically figure out what target
hooks should be using. So simplify it:
- drop before hooks entirely, they don't seem to be very useful;
- commands with special requirements now fire their own after hook (for
example, if they change session or window, or if they have -t and -s
and need to choose which one the hook uses as current target);
- commands with no special requirements can have the CMD_AFTERHOOK flag
added and they will use the -t state.
At the moment new-session, new-window, split-window fire their own hook,
and display-message uses the flag. The remaining commands still need to
be looked at.
- Prepare the state again before the "after" hooks are run, because the
command may have killed or moved windows.
- Use the hooks list from the newly prepared target, not the old hooks
list (only matters for new-session really).
- Correctly detect an invalid current state and ignore it in
cmd_find_target ("killw; swapw").
- Change neww, new, killp, killw, splitw, swapp, swapw to update the
current state (used if no explicit target is given) to something more
useful after they have finished. For example, neww changes it to the
newly created window.
Hooks are still relatively new and primitive so there are likely to be
more changes to come.

the state (client, session, winlink, pane) for it it before entering the
command. Each command provides some flags that tell the prepare step
what it is expecting.
This is a requirement for having hooks on commands (for example, if you
hook "select-window -t1:2", the hook command should to operate on window
1:2 not whatever it thinks is the current window), and should allow some
other target improvements.
The old cmd_find_* functions remain for the moment but that layer will
be dropped later.

options for "mouse-this" and "mouse-that", mouse events may be bound as
keys and there is one option "mouse" that turns on mouse support
entirely (set -g mouse on).
See the new MOUSE SUPPORT section of the man page for description of the
key names and new flags (-t= to specify the pane or window under mouse
as a target, and send-keys -M to pass through a mouse event).
The default builtin bindings for the mouse are:
bind -n MouseDown1Pane select-pane -t=; send-keys -M
bind -n MouseDown1Status select-window -t=
bind -n MouseDrag1Pane copy-mode -M
bind -n MouseDrag1Border resize-pane -M
To get the effect of turning mode-mouse off, do:
unbind -n MouseDrag1Pane
unbind -temacs-copy MouseDrag1Pane
The old mouse options are now gone, set-option -q may be used to
suppress warnings if mixing configuration files.
mostly useless and annoying messages. Change those commands to silence
on success like all the others. Still accept the -q command line flag
and "quiet" server option for now.
descriptors rather than strings.
- Each session still has a current working directory.
- New sessions still get their working directory from the client that
created them or its attached session if any.
- New windows are created by default in the session working directory.
- The -c flag to new, neww, splitw allows the working directory to be
overridden.
- The -c flag to attach let's the session working directory be changed.
- The default-path option has been removed.
To get the equivalent to default-path '.', do:
bind c neww -c $PWD
To get the equivalent of default-path '~', do:
bind c neww -c ~
This also changes the client identify protocol to be a set of messages rather
than one as well as some other changes that should make it easier to make
backwards-compatible protocol changes in future.
