Release LXQt 0.12.0

The LXQt team is proud to announce the release of LXQt 0.12.0, the Lightweight Qt Desktop Environment.

The LXQt team is working hard towards LXQt 1.0.0. Want to help us? Found any bugs? Please file bug reports and pull requests on our GitHub tracker: https://github.com/lxqt/lxqt/issues

The list of changes is also available in our CHANGELOG files.

Highlights

New Open/Save File dialog -> Qt apps use the newly designed file dialog with all the features as provided by pcmanfm-qt
Support for icon themes with the FollowsColorScheme (KDE extension to XDG icon themes standard)
Better support for HDPI displays (using the Qt’s Qt::AA_UseHighDpiPixmaps)
All binaries now support the basic parameter handling (–help & –version)
Added LXQT_CONFIG_PATCH_VERSION to all packages - aka we are now able to make point releases and show the actual version of each package within the basic cli, not only that of liblxqt.
Code optimization - using const variables and iterators wherever possible to speed up LXQt and make it more robust in general
Dropped lxqt-common - the files are moved to the repositories of particular components, that they belong to
Created the new lxqt-themes component
Improved ending session for shutdown/reboot -> shutdown all LXQt components first and then let the job for init (systemd)

Notes For Packagers

We introduce some fundamental changes with this release - mostly related to the removal of lxqt-common. The files from lxqt-common are moved to the packages in which they best fit – to make this transition smooth you will need to add some breaks/replaces in your packages to avoid package management complaints about files being in more than one package at the same time. Here is what works with Debian-based packaging:

compton-conf - Breaks/Replaces: lxqt-common (« 0.12.0)
lxqt-globalkeys - Breaks/Replaces: lxqt-common (« 0.12.0)
lxqt-notificationd - Breaks/Replaces: lxqt-common (« 0.12.0)
lxqt-policykit - Breaks/Replaces: lxqt-common (« 0.12.0)
lxqt-session - Breaks/Replaces: lxqt-common (« 0.12.0)
lxqt-themes - Breaks/Replaces: lxqt-common (« 0.12.0)
pcmanfm-qt - Breaks/Replaces: lxqt-common (« 0.12.0)

Please also be aware that lxqt-qtplugin needs to pickup a new dependency libfm-qt(-dev). lxqt-session should pick up lxqt-themes or lxqt-theme.

Important Note: lxqt-panel will need libqtxdg >= 3.1.0 at minimum so it would be a good idea to package that first.
