Any issues with 5.12 version?

Dear KNIMErs,

On one hand, I had serous issues with using 5.12 LTS version. Finally, downgraded back to 5.8.3 LTS.

On the other – I have found just a couple of posts on KNIME Community #Excel Reader in 5.12 - seriously, KNIME? and on LinkedIn https://www.linkedin.com/posts/emanuelalexandretavares_knime-it-is-unacceptable-the-kind-of-issue-share-7480596346182299648-VRvu/?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAALuFAB0HWlig3Xd3kZEu1UNv1Kw9rI04Q mentioning issues with the newest version.

Thus the question is: is there a global issue with 5.12 version or I just had bad luck to face the issues?
