From the source:
When starting i3 initially (and after each change to the connected
outputs), this function fixes the resolution of the __i3
pseudo-output. When that resolution is not set to a function which
shares a common divisor with every active output’s resolution,
floating point calculation errors will lead to the scratchpad window
moving when shown repeatedly.
fixes#632
Since we advertise _NET_ACTIVE_WINDOW support (but only set the
corresponding atom currently), it makes sense to also support the
ClientMessage. Apps such as Gajim use it to set focus to the roster
window when clicking on the tray icon for example.
fixes#767
Compilers store the path with which they were called in the debug
symbols. Therefore, this will make backtraces show something like
../i3-4.2/src/main.c instead of src/main.c.

Therefore, we enable pre-compiled headers only when CC=clang.
This is useful for third-party scripts which require certain features
and want to error out cleanly when they are run with an old i3 version.
Additionally, i3 --version might be different from what’s actually
running (an old version of the binary), so i3-msg -t get_version will be
the best way to figure out the i3 version you are actually running from
this commit on.
With this commit, the "default" layout is replaced by the splith and
splitv layouts. splith is equivalent to default with orientation
horizontal and splitv is equivalent to default with orientation
vertical.
The "split h" and "split v" commands continue to work as before, they
split the current container and you will end up in a split container
with layout splith (after "split h") or splitv (after "split v").
To change a splith container into a splitv container, use either "layout
splitv" or "layout toggle split". The latter command is used in the
default config as mod+l (previously "layout default"). In case you have
"layout default" in your config file, it is recommended to just replace
it by "layout toggle split", which will work as "layout default" did
before when pressing it once, but toggle between horizontal/vertical
when pressing it repeatedly.
The rationale behind this commit is that it’s cleaner to have all
parameters that influence how windows are rendered in the layout itself
rather than having a special parameter in combination with only one
layout. This enables us to change existing split containers in all cases
without breaking existing features (see ticket #464). Also, users should
feel more confident about whether they are actually splitting or just
changing an existing split container now.
As a nice side-effect, this commit brings back the "layout toggle"
feature we once had in i3 version 3 (see the userguide).
AFAIK, it is safe to use in-place restart to upgrade into versions
after this commit (switching to an older version will break your layout,
though).
Fixes#464
e.g. pressing Mod1+x when having the following in your configfile:
bindsym Mod1+x some invalid command
will lead to an i3-nagbar instance popping up, offering you to view the
error log (which will contain parser errors from this commit on).
This workaround is necessary for terminal emulators which parse -e in a
different way: some accept a list of arguments (-e command arg1 arg2 …),
some accept only one argument (-e "command arg1 arg2 …"). Therefore, we
just create a script and pass that as the one and only argument.
CPPFLGES, CFLAGS and LDFLAGS should be user variables
We now provide default flags but use I3_*FLAGS flags for our own needed
flags
Also reoder lib flags a bit
In certain situations (when you have a h-split within a h-split) you
couldn’t properly resize previously. This commit makes the resize
command properly traverse up the containers.
fixes#754
This fixes a race condition when running the tests. I think that the X11
server has more time to clean up the resources when we do an explicit
disconnect. The symptom I was seeing was that sometimes, i3 couldn’t
become the window manager on one of the Xdummy instances.
Depending on the memory layout, it could happen that bind->command was
exchanged with something else while the parser still accessed it.
Therefore, we now copy the command and let the parser use that copy.
