Breaking Changes:
* The new config parser imposes some restrictions on which characters can be
used in section and key names. Users shouldn't be affected by, this unless
they use one of the following characters in any section or key name: `"'=;#[](){}:.$\%`
Please consult [`man 5 polybar`](https://polybar.readthedocs.io/en/latest/man/polybar.5.html) for a full reference of the new config rules.
* `internal/temperature`: The first and last ramp element are now only used for
`base-temperature` and below and `warn-temperature` and above respectively.
This only slightly changes the ranges for which the different ramp levels are
responsible for.
(#2197)
Changelog
**Deprecations**
* `[settings]`: `throttle-input-for` has been removed. It wasn't a useful option
and could cause certain actions (e.g. click commands) to be ignored. (#2117)
* All action names used by modules to handle click and scroll events are
deprecated (#1907). This change mainly affects users of the menu module.
Please read the [documentation](https://polybar.readthedocs.io/en/latest/user/actions.html) for instructions on how to migrate.
**New Config Options**
The `include-directory` key can be used the same as `include-file` and includes
all regular files in the given directory.
In labels:
* `label-NAME-minlen`, `label-NAME-alignment` can be used to pad labels with
spaces to the right (alignment set to `left`), left (alignment set to
`right`), and both sides (alignment set to `center`).
In `internal/backlight`:
* `enable-scroll` enables changing the brightness through scrolling.
In `internal/github`:
* `format-offline` is used when the module cannot connect to the server.
* `label-offline` can be used in `format-offline`.
* `api-url` can be used to connect to a custom github enterprise instance
In `internal/pulseaudio`:
* `click-right` and `click-middle` can be used to execute commands when
right/middle clicking.
* `%decibels%` token can be used in `label-volume` and `label-muted` to show the
volume in decibels.
**Changes To The Build System**
* Allow users to specify python executable when building. (polybar/xpp#27,
#2125)
* The i3ipcpp submodule no longer rebuilds jsoncpp and just uses whatever
version is available. (#2015, polybar/i3ipcpp#9)
**Features**
* New commandline argument: `-M` / `--list-all-monitors`.
Will display all available monitors (even cloned ones).
* New log level: `notice`.
Used as the default and is used for non-warning messages the user should
nevertheless be aware of. (#2027)
* config:
* New config parser (#1377)
* `include-directory` key (#2196), see #1946
* Add error message when an entire section is missing. (#2195)
* `-minlen` and `-alignment` properties for labels. (#1546)
* Make the `seperator` key in the bar section a label. (#1918)
* Better color validation. (#1290)
* timer modules: Schedule module updates to be aligned with the update interval.
For example, the date module now updates on the minute instead of in the
middle of a minute if the interval is set to 60 seconds. (#2123), see #2064
* `custom/menu`: Multiple menu modules per bar (#1907)
* `internal/backlight`: Support for changing the brightness through scrolling.
This may require additional changes to the system running polybar. (#1957)

* `format-offline` for when the module cannot connect to the server (#1825),
see #1815
* Support for github enterprise instances. (#1841), see #1812
* `internal/network`: Support `Gbit/s` for `%linkspeed%` token. (#2055)
* `internal/pulseaudio`:
* `click-right` and `click-middle` keys (#1941)
* `%decibels%` token (#1894), see #1886
* `internal/xworkspaces`: Proper implementation for `label-occupied`. (#822),
see #874, #1444, #1033
**Fixes**
* Polybar not executing commands that produce output. (#1680), see #916
* Polybar froze until click commands finished executing (#2248)

#1794
* Unstable animation framerate (#1683), see #568
* Multiple modules of the same type caused click events not to be delivered to
the rigth one (#1907), see #1172
* config:
* Seemingly unrelated error messages when BOM character appears in config.
(#2166), see #2075
* Fall back to next possible config location if config file doesn't exist
(except if `--config` was used). (#2026), see #2016
* iconset: `fuzzy-match` chose first match, even if exact match was available.
(#2042), see #2041
* `custom/menu`: Spacing issue (#1656)
* `internal/alsa`: Volume didn't go over 100% (#2184), see #2173

`amdgpu_bl`. (#2122)
* `internal/battery`: Battery not marked as full if over `full-at` percent.
(#2019), see #1622
* `internal/cpu`: More accurate cpu load calculation. (#1955)

It was not quite clear how try_apply_alpha should behave if the given
color was not ALPHA_ONLY. The implementation just returned 'this'.
However, the build relied on it returning the given color.
This broke all bg and fg settings in the entire bar.
To clear this up, we switch this around take the alpha channel of 'this'
and also return 'this' if it isn't ALPHA_ONLY.
Fixes#2255
Shell commands triggered from action tags used to block polybar until
they finished.
Since we are not actually interested in the output of the commands, it
makes sense to run them completely detached from polybar and have
polybar not block when executing these commands.
Now the spawned child processes no longer get killed when polybar
exits. This is fine because polybar is not responsible for these
processes since they were explicitly started by the user through click
commands.

The intent is for every color to be stored in a rgba instance
The rgba class now stores the color in a 32 bit integer to save space
This also removes the unused class rgb and moves everything else into a
cpp file.
Many functions also had weird template parameters. For example
alpha_channel<unsigned short int> would give a 2 byte number with the
alpha channel byte in both bytes.
color_util::hex would return a hex string with alpha channel if unsigned
short int was given and without if unsigned char was given. Even more
curiously those parameters were passed to *_channel and the result
nevertheless truncated to 8bits.
We no longer allow people to create issues from a blank template.
The templates for bug reports and build issues are also much more
explicit in what they want from the user.
Only modules can now be action handlers.
This also slightly simplifies the controller because we don't need to
keep track of input handlers, we can just use the module list.
The next action should always select the next workspace, the same for
prev.
reverse-scroll should be directly used when setting the scroll actions.
This changes the behavior of `prev` and `next` actions in the i3 and
bspwm module.
But I don't think the impact will be significant and the old behavior
was misleading anyway.
Some actions have data attached (e.g. xworkspaces-focus=N), the
forwarding logic now matches the keys in the legacy_actions map as
prefixes and everything afterwards is considered additional data and
appended to the new action string.
All modules now expose their actions as public static constants
Issues: The menu module no longer closes when an item is clicked (before
it would intercept any executed command and look if it matches one of
its exec commands)
