[xwiki-devs] [Brainstorming] Not upgrading runtime libraries during stabilization releases (4.4 and 4.5)

Hi devs, I'm wondering about something following Thomas' upgrade of JGroups from 3.2.0 to 3.2.5. I'm not sure if we should continue doing upgrades of libraries during the 2 stabilization releases (4.4 and 4.5) since an upgrade always introduces a risk. I think the exception is when it fixes an important known issue that we have. WDYT? Thanks -Vincent
