terminal features, each of which are defined in one place and map to a
builtin set of terminfo(5) capabilities. Features can be specified based
on TERM with a new terminal-features option or with the -T flag when
running tmux. tmux will also detect a few common terminals from the DA
and DSR responses.
This is intended to make it easier to configure tmux's use of
terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5)
databases or for features which do not yet have a terminfo(5) entry.
Instead of having to grok terminfo(5) capability names and what they
should be set to in the terminal-overrides option, the user can
hopefully just give tmux a feature name and let it do the right thing.
The terminal-overrides option remains both for backwards compatibility
and to allow tweaks of individual capabilities.
tmux already did much of this already, this makes it tidier and simpler
to configure.

condition. From Anindya Mukherjee.
reference to it, it isn't necessary that the pane in copy mode is the
same as the one copying from. Add a -s flag to copy-mode to specify a
different pane for the source content. This means it is possible to view
two places in a pane's history at the same time in different panes, or
copy from a pane's history into an editor or shell in the same pane.

- Add double and triple click bindings to copy a word or line outside
copy mode. The text is selected for a short period to show what has
been copied. This is in line with the existing mouse selection where
the text is copied and the selection is cleared when the mouse button
is released.
- Change the existing double and triple click bindings in copy mode to
behave in the same way.
- Add a button 2 binding to paste the top buffer.
use this to add descriptions to the default key bindings. A new -N flag
to list-keys shows key bindings with notes rather than the default
bind-key command used to create them. Change the default ? binding to
use this to show a readable summary of keys.
Also extend command-prompt to return the name of the key pressed and add
a default binding (/) to show the note for the next key pressed

Change remain-on-exit and window-style/window-active-style to be pane

parser using yacc(1). This is a major change but is clearer and simpler
and allows some edge cases to be made more consistent, as well as
tidying up how aliases are handled. It will also allow some further
improvements later.
Entirely the same parser is now used for parsing the configuration file
and for string commands. This means that constructs previously only
available in .tmux.conf, such as %if, can now be used in string commands
(for example, those given to if-shell - not commands invoked from the
shell, they are still parsed by the shell itself).
The only syntax change I am aware of is that #{} outside quotes or a
comment is now considered a format and not a comment, so #{ is now a
syntax error (notably, if it is at the start of a line).
This also adds two new sections to the man page documenting the syntax
and outlining how parsing and command execution works.
Thanks to everyone who sent me test configs (they still all parse
without errors - but this doesn't mean they still work as intended!).

changes to allow the status line to be entirely configured with a single
option.
Now that it is possible to configure their content, enable the existing
code that lets the status line be multiple lines in height. The status
option can now take a value of 2, 3, 4 or 5 (as well as the previous on
or off) to configure more than one line. The new status-format array
option configures the format of each line, the default just references
the existing status-* options, although some of the more obscure status
options may be eliminated in time.
Additions to the #[] syntax are: "align" to specify alignment (left,
centre, right), "list" for the window list and "range" to configure
ranges of text for the mouse bindings.
The "align" keyword can also be used to specify alignment of entries in
tree mode and the pane status lines.

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).
