Pyroma 5.0 (#112)

* Get rid of the setup monkey things

That includes testing super old distruibutions of distribute, as we no
longer have no intention of supporting such old packaging.

* We now have to have the build systems installed to get any data out of them

So flit_core is needed for testing.

* Updated changes

* Preparing release 5.0a1

* Back to development: 5.0a2

* Use Core Metadata namings internally

Also added an error if the build system failed.

* Better handling of various build errors

* Preparing release 5.0b1

* Back to development: 5.0b2

* Fixed a bug in the new Licensing handling

* Preparing release 5.0b2

* Back to development: 5.0b3

 Changelog
 =========
 
-4.3.4 (unreleased)
+5.0b3 (unreleased)
 ------------------
 
 - Nothing changed yet.
 
 
+5.0b2 (2025-07-10)
+------------------
+
+- Fixed a bug that failed to find license-expression fields.
+
+
+5.0b1 (2025-07-04)
+------------------
+
+- Changed the internal metadata names to match Core Metadata. This brings
+  less confusion, especially since setuptools and PyPI aren't exactly the
+  same either, so let's pick the offical standard and run with it.
+
+- Added a rating for if the wheel fails to build. Unfortunately it's
+  impossible to get a proper error out of it, so the message tells
+  you to run python -m build.
+
+
+5.0a1 (2025-07-02)
+------------------
+
+- Removed support for fetching data via monkey-patching setup.py.
+
+- Added a warning if you have only a setup.cfg, something that is
+  working with some tools, but is not officially supported.
+
+- Some general cleanups and simplifications thanks to those changes.
+
+
 4.3.3 (2025-07-03)
