Dear EasyBuilders,

We're happy to announce the release of EasyBuild v4.5.1 [1].

As usual the world around us tried to distract you from this glorious event, for example by mutating viruses, or by suddenly uncovering that a feature of a popular logging library can be abused in creative ways...
What will they think of next!

Forget about EasyBuild v4.5.0 being the best release ever, that's old news now, since EasyBuild v4.5.1 is way better!
We bet you didn't see that coming...


EasyBuild v4.5.1 is primarily a bugfix and update release, but it also includes various minor enhancements.

Highlights for this release are listed below. More details are available in the release notes [2] which includes links to the respective pull requests for more detailed information.

(this information is also available at https://github.com/easybuilders/easybuild/releases/tag/easybuild-v4.5.1)
