@aladinor Thanks for taking this on.

I have only two suggestions:

1. fix version/release date in https://github.com/openradar/xradar/blob/main/CITATION.cff
2. maybe merge MNT: Improve Contributing Guide #354 before release

[aladinor]

Should we add #362 and #363 perhaps in this release?

[kmuehlbauer]

@aladinor I'm on board with getting these two into the release, if we get consensus/merge fast. Otherwise, version numbers are cheap. We can have a new release anytime soon.

[aladinor]

Probably, we can move forward with the current release, including #362, and then wait for more feedback from the @openradar/xradar community. What do you think @kmuehlbauer?

[aladinor]

@kmuehlbauer, let me know if everything looks great to you and we can release 0.12.0

[kmuehlbauer]

@aladinor I've updated the release date to today (April 21st). Also fixed CITATION.cff. I'll merge, when we get green lights.

[kmuehlbauer]

@aladinor So, this is green. It would be well deserved to let you finalize this version. Please go ahead, merge and release 🚀.
