Security:

• In previous versions, RT's native login system is vulnerable to user enumeration
  through a timing side-channel attack. This means an external entity could try to
  find valid usernames by attempting logins and comparing the time to evaluate each
  login attempt for valid and invalid usernames. This vulnerability does not allow any
  access to the RT system. This vulnerability is assigned CVE-2021-38562 and is fixed
  in this release.

Updates:

• Remove search string including numbers in ticket autocomplete search on select
• Use the correct CurrentUserCanSetOwner return value.
• Find full path for processing acl files on upgrade
• Find full path for processing index files on upgrade
• Convert to abs path before executing initialdata files
• Remove extra closing div on Login/Logout pages
