74	74	Hibernate has (finally) been upgraded to the very last version. While it means you will benefit from bugfix/improvement/new features it's also a huge jump (previous version was close to 10 years old) and you will probably have issues if you are directly manipulating Hibernate APIs or some library expecting a much older version of Hibernate. You can find the details on https://github.com/hibernate/hibernate-orm/wiki/Migration-Guides but here is an extract from XWiki point of view:
75	75
76		-* HQL '##?##'-based wildcards are not supported anymore at all by Hibernate. We added an automatic converter (to '##?1##' JPQL style) which seems to work well but it might not be perfect and it's producing a deprecating warning log
77		-* You might need to update your ##hibernate.cfg.xml## file
78		-* Various Hibernate classes have been removed or moved to different Java packages
79		-* Various Hibernate methods have been removed from the XWiki APIs or not having any effect anymore even if still here and deprecated
