The 10.5.1 release addresses a pair of bugs that were picked up shortly after the 10.5.0 release. The issues in question effect those using j2ee session handling in Lucee (non-default) and MS SQL Server users.
The j2ee session issue is a bug that we have reported with Lucee: https://luceeserver.atlassian.net/browse/LDEV-776. If you want to protect your sessions from fixation and hijacking we suggest that you use cfml sessions for Preside applications until such time that this issue is fixed in Lucee (at which point will also re-enable session rotation for j2ee sessions).
