bluestar-linux-4.5.1-deskpro-plasma5-2016.04.24 is available for download.
The new release includes the latest versions of kde5/plasma5 and the latest kernel, linux-4.5.1.
The autostart call to cairo-dock has been changed to 'cairo-dock -c' disconnecting it from opengl. Those who would prefer using the opengl backend, simply edit $HOME/.config/autostart/cairo-dock.desktop and change the 'Exec' component, removing the '-c' option. I have found that using the cairo-dock backend seems to be more stable than using opengl - at least when using the nouveau graphics driver.
The graphical installer has been updated from v1.1.4 to v2.2.1 - this includes a new partition manager which I hope will resolve some disk partitioning issues, the existence of which I was only recently made aware. Some anomalies in the settings were also corrected.
The command line installer was also tweaked, removing language installation and the setting of desktop language. These functions have become redundant because all languages are now included with kde5/plasma5. Setting your desktop language can be done with systemsettings->Regional Settings. I had initially modified the installer script to build a language menu for an initial language setting, but due to memory constraints imposed by an increase in kde5/plasma5 memory usage, building the menu caused the installer to crash, despite working perfectly in a test environment. I may revisit this for my next build.
I have noticed that plasma5 uses a lot more memory than plasma4. There are bug reports that suggest there may be memory leaks, but none of these have been resolved. I strongly recommend that users keep an eye on their /var/lib/systemd/coredump directory - too many core dumps could fill your file system to the point where you cannot log in. For those not interested in chasing down the cause of the core dumps, make sure to keep this directory cleaned out (or mount /var on a separate partition). Personally, I only see this issue on the one system that uses the nouveau graphics driver.
That said, the current incarnation of kde5/plasma5 appears to be somewhat more stable than it has been - baby steps, I guess.
