Release Notes
This is a preview version of Opera. Use only on properly backed up computers and do not install over previous Opera versions.
This release uses a new account storage format. If you install over an existing profile, you will be prompted to convert all accounts into the new format. This will not require a re-index. You will not be able to use the reformatted e-mail with previous versions of Opera.
Emptying trash may prevent new IMAP messages from downloading until Opera is restarted.
Undeleted IMAP e-mails are returned to trash when checking for new mail.
