Note:

• originally, the easybuild-4.2.0 release was accidentally published to PyPI (on Tue April 15th 2020 at 2:28pm UTC) with an incorrect setup.py file, which specified easybuild-easyblocks==4.1.1 and easybuild-easdyconfigs==4.1.1 in requires and install_requires, see

  easybuild/setup.py

  Line 39 in 80c981c

  VERSION = '4.2.0'

  and

  easybuild/setup.py

  Lines 82 to 88 in 80c981c

  	requires=[
  	'easybuild_framework(==%s)' % VERSION,
  	# there is no 4.1.2 release for easyblocks/easyconfigs,
  	# only for framework (which includes an important security-related bug fix)
  	'easybuild_easyblocks(==4.1.1)',
  	'easybuild_easyconfigs(==4.1.1)',
  	],

• hardcoding easyblocks and easyconfigs was done during the quick release of EasyBuild v4.1.2 (cfr. https://github.com/easybuilders/easybuild/pull/609/files#diff-2eeaed663bd0d25b7e608891384b7298);

• setup.py for EasyBuild v4.2.0 was fixed in 3a8c81b, shortly after easybuild-4.2.0 was published on PyPI;

• a new release of the easybuild package on PyPI was published as easybuild-4.2.0.post0 (since re-releasing under the exact same version is not allowed by PyPI, rightfully so), using the fixed setup.py from 7f8f08f;

• shortly after easybuild-4.2.0.post0 was released to PyPI & tested, the faulty easybuild-4.2.0 package was removed (on Tue April 15th 2020 at 3:50pm UTC), to avoid confusion & faulty installations of EasyBuild v4.2.0 (it was only available on PyPI for 1h22m);

• the bootstrap installation of EasyBuild was re-tested after easybuild-4.2.0.post0 was published and after the easybuild-4.2.0 package was removed, and found to be working as expected;

• this faulty release of easybuild-4.2.0 could have only been picked up with direct installations from PyPI (using pip install easybuild), or when running the bootstrap__eb.py script when the faulty package was still available (between 2.28pm and 3.50pm (UTC) on Tue April 15th 2020)
