We were running 3.8.2 without trouble. We have an external user system which then drops the right cookies/session info for vBulletin to use. Since upgrading to 3.8.3* it seems this information is no longer carried across sessions (close browser and reopen it).
Were any changes made from 3.8.2 -> 3.8.3 related to login/cookie/session? I'm not looking for specific technical assistance* just want to know if there is some new changes we have to deal with or something else is playing a role...
