The hook is optional, see https://www.python.org/dev/peps/pep-0517/#prepare-metadata-for-build-wheel

This is not yet automatically detected because the feature is provisional.
Use `%pyproject_buildrequires -w` to opt-in.
Resolves: rhbz#2060109
Apparently, when you repeatedly run `rpmbuild -ba`, files in %_builddir are not cleaned.
This way, we at least make sure the files are unique between different NVRAs,
so 2 unrelated builds don't share the files between each other.
Keeping files contained in the build subdirectory is the more common way of doing this,
but we cannot technically do that, because we don't know what's it gonna be (before %prep).
Should be backwards compatible, as we only modify underscore-prefixed macros and %{pyproject_files},
where the exact value should not matter to the packagers.
Resolves: rhbz#2060109
This package is already installed -- otherwise the macro would not even exist.
However, since python3-devel has started to Require pyproject-rpm-macros,
it is no longer possible to use `repoquery --whatrequires pyproject-rpm-macros`
to get a reliable list of packages that use the macros.
This was, all packages that use %pyproject_buildrequires will BuildRequire the macros explicitly.
(In the future, we could even include a stub version of %pyproject_buildrequires
in pyproject-srpm-macros (always installed in the buildroot),
that only echoes this package,
so packagers would not need to manually BuildRequire anything at all.)

Compressed manpages have different extension than those listed in the RECORD file,
so they were not recognized when %%pyproject_save_files '+auto' flag
was provided.
To enable the path recognition, if the manpage extension matches the one
listed in brp-compres, the extension is removed, and an asterisk is now added
to the manpages filenames.

%%pyproject_save_files newly saves also a list of importable modules.
The list is used by %%pyproject_check_import to invoke the import test
on each module name.
%%pyproject_check_import accepts two options:
-t: filter only top-level modules
-e: exclude module names matching the given glob from the import check

%pyproject_buildrequires macro now accepts multiple file names to load
additional dependencies from them.
New option -N was added to disable automatical generation of requirements
in case package does not use build system. Option -N cannot be used in
combination with options -r, -e, -t, -x.

This allows users to do:
%build
cd somewhere
%pyproject_wheel
cd -
cd somewhere_else
%pyproject_wheel
cd -
%install
%pyproject_install
Without a need to copy paste the wheels to a common location.
This is in fact a breaking change, I'll make sure to adapt the affected packages in Fedora.
