 +  * GCC (C, C++, Fortran) is at version 10 now
   * Wayland: the official Fedora release notes have a lot of information about Wayland, a replacement for the X11 graphics system. We don't use Wayland at this time, since it doesn't yet support many features that are needed in our type of work (remote graphics, VNC, various scientific programs, ...). So you can ignore all that is written about Wayland in the documentation.   * Wayland: the official Fedora release notes have a lot of information about Wayland, a replacement for the X11 graphics system.

 +  * Fedora has ''earlyOOM'' enabled, a background proces that monitors for Out-of-Memory conditions, and attempts to kill the offending processes before the system comes to a grinding halt. Hopefully, this will mean there will be less system crashes (out-of-memory is one of the biggest reasons for Linux desktop crashes nowadays)
 +  * FlexiBLAS is an intermediate interface to the BLAS and LAPACK libraries, making it possible to switch between various implementations of these libraries. The downside is, that you will need to recompile programs that are linked with BLAS or LAPACK (including private copies of numpy!)

   * VNC issues: Desktop environments that require hardware accelleration (3D desktop effects) are too heavy to be used inside a virtual desktop (VNC, X2GO).

   * TeX package ''psfig'', which has been obsolete for a long time, has now almost completely stopped working. Converting documents to newer packages such as ''graphics'' or ''graphicx'' is recommended, and is usually easy.   * TeX package ''psfig'', which has been obsolete for a long time, has now almost completely stopped working.

-  * <del>Solved: the current version of Python package [[tensorflow]] seems to work fine now with any version of python 3, making installation much easier</del> 
   * Gnome doesn't display //notification area// aka //system tray// icons any more by default. The fix is, to enable  the ''topicons plus'' extension: open ''gnome-tweaks'', and go to ''extensions'' to do that. After that, the icons such as status icons of dropbox, skype etc, will be in your top panel.   * Gnome doesn't display //notification area// aka //system tray// icons any more by default.

-  * Applications using the "pango" text rendering engine (including Gnome, Cinnamon and MATE desktops) will no longer support bitmap fonts. If an application looks strange, you may have to select a different font for it (seen on terminal emulators, emacs with non-standard settings, possibly other applications)+  * Applications using the "pango" text rendering engine (including Gnome, Cinnamon and MATE desktops) will no longer support bitmap fonts.

-  * <del>Bleachbit (file cleaner) works, but seems to display wrong icons: the "search" icon is grayed out, but is available for clicking, and the "clean" icon to start cleaning, shows as a grayed out x, so might be mistaken for an abort icon. The help text shown when the mouse is over the icon, shows the right description for each task.</del> (fixed in update) 
-  * <del>Solved: Quota reporting is currently not working (solved as long as users use supplied alias)</del>

   * The ''clipit'' clipboard app that is a default part of Gnome, Cinnamon and MATE desktops, sometimes hangs, which blocks all cut, copy and paste actions. Exit the app by right-clicking on the icon (which looks like a clipboard), and choose the quit action. If this happens a lot to you, you might want to disable the app in your startup applications preferences.   * The ''clipit'' clipboard app that is a default part of Gnome, Cinnamon and MATE desktops, sometimes hangs, which blocks all cut, copy and paste actions.
