5.2.1 has 2 very simple new features:

  • The year when selecting dates is now always 4 digits.
  • The index database is no longer opening and closing for each email.

Additionally, a couple of bugs were fixed:

  • Fixed a problem with getting the number of emails for AppleMail.
  • The search is reset correctly when using a filter.
  • Fixed a problem with the mailboxes not refreshing correctly in the Setup.
  • Fixed an OutOfBoundsException when connecting to the index database.
  • When archiving with an older than date the date no longer is missing after opening the Setup window.
  • The Easy version no longer makes a "broken pipe" error when sending emails.
