+    * Note: Gnome versions used to be 3.38 etc, now the ''3.'' is dropped, so Gnome 43.
     * Various Gnome shell extensions that you can load for yourself from [[https://extensions.gnome.org/]]
   * Cloud integration: you can link your [[linux:Google Drive]], [[linux:OwnCloud]]/SurfDrive and some other cloud storage services the file manager (in addition to [[linux:Dropbox]], which has been there for a couple of years). \\ Various online calendars can be integrated in the desktop calendar utility.
-    * Unfortunately, Dropbox integration is not fully working at the moment.
+  * Due to a change in the inner workings of the ''nautilus'' file manager, many of its plugins are no longer available. These will be added back when they are updated to match the new version
+    * This includes Dropbox integration, which is not fully working at the moment. You can still run the dropbox tool to have synchronization, but you will not be able to see from within the file manager if files have been synchronized, or use any of the specific functions from the file manager interface.
   * **Python is now by default 3.11**. You can still call ''python2'' to get a python 2.7 interpreter, but NO PACKAGES are installed for it any more; so you can just use this to build your own python2 environment if needed.
     * Command ''python'' will now invoke python 3.11 so **check your own scripts**.
     * If you still need python2, a private install or virtualenv will still be possible, but for many packages, you may have to explicitly install an older version (e.g. ''pip2 install --user astropy==2.0.12'')
     * To install a python2 kernel in jupyter,a personal setup can be made using ''python2 -m ipykernel install --user''
-    * We also have the interpreters of python 3.6, 3.7, 3.8 and 3.9 installed, for compatibility and in case you need them for your own projects or virtualenvs. As with python 2, these are the bare interpreters, we do not provide a complete stack of modules for these older versions.
+    * We also have the interpreters of python 3.6, 3.7, 3.8, 3.9 and 3.10 installed, for compatibility and in case you need them for your own projects or virtualenvs. As with python 2, these are the bare interpreters, we do not provide a complete stack of modules for these older versions.
     * To move your personally installed modules from python 3.10 (Fedora 35) to python 3.11:
       * Setup ''pip'' for the old python version: ''python3.10 -m ensurepip --user''
       * Make list of installed packages with versions: ''python3.10 -m pip freeze > installed.txt''
       * Install the same packages into the current python: ''python3 -m pip install --user -r installed.txt''
-    * Many 3rd party build and install scripts don't seem to understand that 3.10 > 3.9, so if something complains our python is too old, the program just doesn't compute.
+    * Some 3rd party build and install scripts still don't seem to understand that 3.11 > 3.9, so if something complains our python is too old, the program just doesn't compute.
-  * GCC (C, C++, Fortran) is at version 11 now. Some older versions are available through environment modules.
+    * Missing: pyregion (not yet made compatible with python 3.11)
-  * CLANG /LLVM compilers are now at version 13. If necessary, compatibility packages of older versions can be added.
+  * GCC (C, C++, Fortran) is at version 12.2 now. Some older versions are available through environment modules.
-  * LibreOffice has been upgraded to version 7.2 with lots of improvements and new features. See [[https://wiki.documentfoundation.org/ReleaseNotes/7.2|Release notes]]
+  * CLANG /LLVM compilers are now at version 15. If necessary, compatibility packages of older versions can be added.
-  * Fedora has ''earlyOOM'' enabled since Fedora 33, a background process 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)
+  * LibreOffice has been upgraded to version 7.4 with lots of improvements and new features. See [[https://wiki.documentfoundation.org/ReleaseNotes/7.4|Release notes]]
-  * 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!)
   * Removed software:
-    * Python 3.4 and 2.6 are no longer available for backward compatibility
     * Several compatibility libraries were dropped. These were libraries to run programs built with very old versions of the GNU compilers (gcc 3.3, 3.4 and 4.1). If you still have binaries from > 10 years ago, recompiling might be advisable.
-    * Due to the removal of some of these very old compatibility libraries, Adobe Reader (acroread) will no longer work; please use a native Linux pdf viewer, such as ''atril'' or ''evince''.
+    * Also, all compatibility with 32-bit executables was dropped. Not surprising, since the last 32-bit machines were bought by our institute in 2006. Known fatalities: ''acroread'', ''supermongo''
-    * ''hdfview'' stopped working in Fedora 31; there are many other programs available that can work with HDF5 files, e.g. ''R'', ''vitables'' or ''veusz''
+      * Please use a native Linux pdf viewer, such as ''atril'' or ''evince'' as a replacement for ''acroread''.
-    * The Flash plugin is no longer supported (Google had supported it until the start of 2021 but not any more).
+      * A workaround for (ancient) ''supermongo'' exists but is not installed by default. If you use this software, please contact us and we can make the workaround available on your desktop.
-    * TeX package ''psfig'', which has been obsolete for a long time, has now been removed. 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 recently been removed. Converting documents to newer packages such as ''graphics'' or ''graphicx'' is recommended, and is usually easy.
-  * Renamed/replaced software
+  * Java is now available in several versions: The last freely obtainable Oracle Java 8.x release; OpenJDK 8, OpenJDK 11, OpenJDK 17 and OpenJDK latest (currently 19).
-    * Python module ''asciitable'' is now part of ''astropy'', at ''astropy.io.ascii'' (see [[http://cxc.harvard.edu/contrib/asciitable/]]) \\ Similarly, ''pyfits'' is now ''astro.io.fits''
-  * Java is now available in 3 versions: The last freely obtainable Oracle Java 8.x release; OpenJDK 8 and OpenJDK 11.
-  * saoimage is no longer maintained as a rpm package. for now, the last binary version still works. Please let us know if this (ancient) astronomical package is still in use.
-  * A workaround for (ancient) ''supermongo'' exists but is not installed by default. If you use this software, please contact us and we can make the workaround available on your desktop.
-==== Known issues in Fedora 35 ====
+==== Known issues in Fedora 37 ====
   * VNC issues: Desktop environments that require hardware accelleration (3D desktop effects) are often too heavy to be used inside a virtual desktop (VNC, X2GO). See [[VNC desktop issues]] for details and workarounds.
-  * 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-extentions-app'' (''Applications - Extensions'' in the menu) to do that. After that, the icons such as status icons of dropbox, zoom etc, will be in your top panel.
+  * X2GO has problems with some desktop environments that try to use "modern" features that are not there on the virtual desktop. For the moment, please use the ''XFCE'' or ''LXDE'' desktops that are known to work.
-  * 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).
+  * An alternative to VNC and X2GO is [[XPRA]], a tool that can forward a single window or an entire desktop to a remote display.
-  * 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 app is only needed to maintain a clipboard history; without it, a single cut/copy and paste is still possible.
+  * Gnome doesn't display //notification area// aka //system tray// icons any more by default. The fix is, to enable  the ''appindicator'' extension: open ''gnome-extentions-app'' (''Applications - Extensions'' in the menu) to do that. After that, the icons such as status icons of dropbox, zoom etc, will be in your top panel.
-  * Workarounds are in place for some software that was built with older versions of CFITSIO (GILDAS) and/or older GFortran (StarLink). When using these programs from within other programs, this workaround may be bypassed (eg, GILDAS software linked from within CASA). If you run into that issue, let us know so we can provide you with the necessary workaround. Eventually these issues are expected to be solved when new versions of these software packages are released or recompiled using current libraries.
+    * Note: in the previous OS versions, there was an extension named ''topicons plus''. If you had that enabled, you will have to enable the new extension now, and possibly remove references to the no longer existing extension.
-  * Some reports that the screensaver on the Plasma (KDE) desktop, sometimes refuses to unlock the screen. To be more precise, when you type your password to unlock, nothing appears on screen. What usually works is to click the icon "virtual keyboard" and enter your password by clicking the characters on screen.
+  * 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 app is only needed to maintain a clipboard history; without it, a single cut/copy and paste is still possible.

If you run into that issue, let us know so we can provide you with the necessary workaround. Eventually these issues are expected to be solved when new versions of these software packages are released or recompiled using current libraries. GILDAS also has a workaround to use python 3.10 in stead of the system default 3.11, with which it fails to compile.
   * Some theme libraries from earlier releases are no longer present. If you get errors when starting graphical applications such as: <code>
    Gtk-Message: Failed to load module "colorreload-gtk-module"
-</code>then go to the settings controlling your desktop look & feel and select another theme
+</code>then go to the settings controlling your desktop look & feel and select another theme instead of the one that uses theme libraries that are no longer present.
