I'be writing up and posting the release notes for 6 RC 2 tomorrow (including subsequent fixes since RC2) tomorrow, the blockers for release of 6 are as follows https://luceeserver.atlassian.net/jira/software/c/projects/LDEV/boards/53 We have a number of issues with initial deployment / in place updating outstanding, as you can see from the board. Being summer, we're slowing down after quite a frenetic sprint to getting to RC1 for CFCAMP. 6 Ain't production ready just yet, but it's functionally complete, only regressions will be addressed What's really important is feedback from testing, running test suites / QA on 6 over the next few weeks will really help the Lucee team deliver a rock solid initial 6 stable release I would also highly recommend upgrading to 5.4.1, it's a solid release. There are a few additional fixes in 5.4.2 SNAPSHOTS so far https://luceeserver.atlassian.net/jira/software/c/projects/LDEV/issues/?jql=project%20%3D[…]%20and%20sprint%20%3D%2065%20ORDER%20BY%20created%20DESC 5.4.x is only bugfixes for now on
