[jbpm-users] JBPM6 and Jira ?

Hi guys, recently I saw lots and lots of commits in jbpm github for the next version, 6.x. that is good... but by the other hand I couldn't see any task in JBPM Jira for those changes... there are 6 "Coding in Progress" and none is related what I saw in github. I'm a bit worried because it seems that such changes will bring a big impact for us that is using 5.x. is there any public resource explaining what is planned to come in next version ? thanks Cristiano
