Hack.Commit.Push Switzerland is just one week away! 🇨🇭 This is a great opportunity to get involved in Open Source projects like @assertj.github.io, with direct guidance from the maintainers!

Hi everyone! An ongoing reorganization at my current employer has prompted me to seek for a new role and would appreciate your support. I'm open to remote (anywhere) and hybrid roles in Switzerland. I have 25+ years experience as a software developer, 8 as devrel www.linkedin.com/posts/aalmir...

#JUnit has a new logo!!! 🚀 To everyone who submitted proposals and participated in the design discussions... Thank You! 👏🏼 github.com/junit-team/j...

#JUnit 6.0.1 is released! #️⃣ Introduce commentCharacter for Csv{File}Source 🔇 Allow disabling JUnit Vintage engine discovery issues 🐞 Bug fixes and enhancements since 6.0.0 docs.junit.org/6.0.1/releas...

#JUnit 5.14.1 is released! 🐞 Bug fixes and enhancements since 5.14.0 docs.junit.org/5.14.1/relea...

"Nobody stops in to check on you. They check on the project. There’s also nobody standing up and saying, ‘hey, thank you for the good work you’re doing to remediate this issue.’" The harsh truth: maintainers give their spare time, yet positive feedback is rare. Appreciate who is behind the code. 💛

As a fellow maintainer of an open source project, this is an intense and somewhat scary read. Thanks to @grobmeier.de for being so open to talk about what he experienced and @github.com for initiating their Secure Open Source Fund! github.blog/open-source/...

The internet was on fire. 🔥 One small library affecting billions of systems. Log4Shell was the biggest security vulnerability of all time. Now, Log4J maintainer, Christian Grobmeier tells us what it felt like inside the flames 👉 github.blog/open-source/...

Our next meetup will take place on November 4th at ING Leeuwarden to help you improve your testing with @timtebeek.github.io covering AssertJ and @simoneromani.bsky.social mutating tests for more confidence. Sign up at www.meetup.com/jug-noord/ev... !

It's great to see the community actively watching over the early development of AssertJ 4!
