+ == Python 2 is deprecated in Fedora 30

+ 

+ Many Python 2 modules were removed from the distribution: packages

+ that only provide Python 2 importable modules, if they are not used by

+ any other package (leaf packages).

+ 

+ While this change should not affect regular users, it will affect

+ developers that use system-packaged Python modules.

+ 

+ If you are developing software that needs to run with Python 2, we

+ recommend using a virtual environment and installing dependencies from

+ the Python Package index (PyPI). See details at:

+ https://developer.fedoraproject.org/tech/languages/python/python-installation.html

+ 

+ We also recommend using a virtual environment (venv) for Python 3, if

+ your software targets the wider Python ecosystem rather than Fedora

+ specifically. Using venv will decouple your development environment

+ from the system.

+ 

+ If you are developing for a Fedora package, please port to Python 3 as

+ soon as possible. Almost complete Python 2 removal is planned for the next

+ release.

+ 

+ == Automatically generated dependencies for Python packages

+ 

+ The generator which generates Provides and Requires for Python RPM

+ packages based on the setup.py file has been enabled by default. This

+ makes the packaging of Python packages easier and more automatic by

+ reusing information provided by the upstream project, and should result

+ in fewer unecessary or missing dependencies in rpms.

+ 

+ == Python progressbar replaced with progressbar2

+ 

+ The progressbar package has been updated to use the progressbar2 fork,

+ which is newer and better maitained.

+ 

+ == Inherited locale settings will be reset on login if necessary

+ 

+ When logging in over ssh or another mechanism, locale settings are

+ forwarded. If the destination does not support that is configured in

+ the source environment, various tools would generate warnings about

+ invalid locale settings. Now, locale is automatically reset to C.UTF-8

+ if such situation is detected.

+ 

+ == Many obsolete RPM scriptlets have been removed

+ 

+ Plenty of installation scriplets in packages are not necessary

+ anymore. Their removal should make installation and upgrades of

+ packages a bit faster.

+ 

+ == Binaries provided by the distribution have optimized linking

+ 

+ The link flags used for Fedora packages have been updated to skip

+ libraries which are not used by the executable. This removes the

+ dependencies on those librararies from various packages, making

+ their installation slightly more efficient.

+ 

+ == Binaries provided by the distribution have additional hardening

+ 

+ The link flags used for Fedora packages have been updated to make the

+ array of function pointers which is used to implement dynamic linking

+ (the GOT) read-only at runtime. This makes it harder for exploit

+ writers to overwrite these function pointers and redirect execution.
