Release notes for i3 v3.δ
-----------------------------

This is the third version (3.δ, transcribed 3.d) of i3. It is considered stable.

This release features tabbing and some more advanced modifications of the
stacking window (see the user’s guide), vim-like marks, support for the
urgency hint, horizontal resizing of containers (finally), modes (which can
make your keybindings a lot simpler), an unlimited amount of workspaces
and several bugfixes (see below for the complete list of changes).

Furthermore, the configuration file parsing has been rewritten to use a
lex/yacc based lexer/parser. This makes our configuration file more easy to
understand and more flexible from the point of view of a developer. For some
of the new features, you already need the new lexer/parser. To not break your
current configuration, however, the old parser is still included and used by
default. I strongly recommend you to add the flag -l when starting i3 and
switch your configuration file to the new lexer/parser. This should only
require minor changes, if at all. In the next released version of i3, the
old configuration file parsing will be removed!

Also, this release includes the testcases which were developed in a separate
branch so far. They use Perl, together with X11::XCB, which you can download
from CPAN. Please make sure you are not doing anything important when running
the testcases, as they may modify your layout and use different workspaces.
They also might, of course, actually find bugs and crash i3 ;-).

Thanks for this release go out to xeen, mist, badboy, Mikael, mxf, Atsutane,
tsdh, litemotiv, shatter, msi, yurifury, dirkson, Scytale, Grauwolf and all
other people who reported bugs/made suggestions.

A list of changes follows:

  * Implement tabbing (command "T")
  * Implement horizontal resize of containers (containers! not windows)
  * Implement the urgency hint for windows/workspaces
  * Implement vim-like marks (mark/goto command)

  * Implement modes which allow you to use a different set of keybindings
    when inside a specific mode
