# Release 0.15.12
The 0.15.12 release of **rofi** focussed on improving overall user experience. These improvements mostly focussed on
three things, first we (tried to) fix the problems with complex keyboard layouts, secondly we tried to make themeing of
**rofi** easier and last we added several speedups. Below I will highlight these bigger changes in more details
The 0.15.12 release of **rofi** focusses on improving overall user experience. These improvements mostly focussed on
three things, first we (tried to) fix the problems with complex keyboard layouts, second we tried to make theming of
**rofi** easier. Also we added several speedups. Below I will highlight these bigger changes in more details
From the next release on, now that **rofi** reached an acceptable maturity level, we will start using more common
version numbering (instead of `0.year.month` that is currently used). Depending on the amount of new bugs discovered I
might decide to make a `1.0.0` release.
Now that **rofi** reached an acceptable maturity level, we will start using more common
version numbering. Right now rofi uses `0.year.month` for version numbers.
Starting with next version the widely used `major.minor.bugfix` scheme will be used.
This means, that next rofi version will either be
* 0.15.13 (bugfix release)
* 0.16.0 (minor release) or (if no major bugs are discovered most likely)
* 1.0.0 (major release)
## Keyboard Layouts
**Rofi** used to have problems with keyboard layouts that used modifier keys to switch between different layouts (unsure
how this is called). These problems should now belong to the past.
**Rofi** used to have problems with keyboard layouts that used modifier keys to switch between different layers.
These problems should now be a thing of the past.
**Note** the syntax for binding keys has slightly changed. The *Mod1*, *Mod2*, etc. keywords are no longer available.
There was no good way to detect how these keys where mapped and if they could be used as modifiers. E.g. if the right
alt (say *Mod3*) is configured to switch between layouts, it cannot work as modifier key to make a `Mod3-p` keybinding.
**Rofi** will now check if the current layout has the *SuperR*,*SuperL*,*AltGr*,*HyperL*,*HyperR* keys available. If they
are available they can be used for keybindings, if not, the user gets a warning.

### DMenu reading from stdin
**Rofi** used to have a custom `fgets` implementation that supported custom separators. The first version in here was
slow and was improved. After a hint of it existence it has now been replaced by the Posix 2008 `getdelim`, this one is
almost as fast as the new custom implementation.
**Rofi** used to have a custom `fgets` implementation that supported custom separators. The first version was
slow but got improved. Learning about Posix 2000' `getdelim` this is now used and is almost as fast as the latest custom implementation.
Overall this gave a speedup of 6x (from 648 ms for 202000 lines down to 108ms).
### Multi-Core power
Still disabled by default, **rofi** can now spawn multiple threads for filtering rows. Depending on the underlying
hardware we saw a 1.5 times speedup running on a dual core ARM and up to a 3.5 speedup on a quadcore (8 thread) i7.
It uses Glib's GThreadPool and will therefor spawn threads when needed, and clean them up again when unused.

To enable this option pass `-threads 0` option, this will autodetect the number number of hw-threads. Pass `-threads 4`
To enable this option pass the `-threads 0` option, this will autodetect the number number of hw-threads. Pass `-threads 4`
to force it to use 4 threads. Setting the number to 1, disables it.
## Themes
**Rofi** color theme can be specified in a lot of detail, using transparency to get the desired results. However this is
not always the easiest to write down and testing it can be a hassle. To solve this we added a web frontend for writing
(and live previewing) themes and a theme repository.

### Theme repository
This has been requested several times and started somewhat on the website. This however got outdated quickly and neither
the themes or the screenshots are correct anymore. To ease this the new repository allows themes to be easily added: you
can export your current configuration directly using **rofi --dump-xresources-theme**, place it in the theme directory
of the repository and the update script will automatically generate screenshots and update the page.
This has been requested several times and rofi's website actually has a theming page.. This however got outdated quickly and neither
the themes or the screenshots are correct anymore. The newly added rofi-themes git repository allows you to add themes easily:
Fork the repository and export your current color theme with **rofi -dump-xresources-theme**. Place it in the theme directory
of the repository and run the update script. This will automatically generate screenshots and update the page.
Update your fork and send a pull request. This way your theme will appear on official themes page, once it's merged.

Big thanks to `SardemFF7` who got tired of me complaining, took the very rough prototype and turned it into
something beautiful.
Hopefully people will make beautiful themes and submit them to the [theme
repository](https://github.com/DaveDavenport/rofi-themes/).
