Today, we're happy to present to our users the culmination of a year's work: the first preview featuring our rewritten IMAP back-end. Please note that this preview is HIGHLY EXPERIMENTAL. Under no circumstances should you use this preview with anything other than a test IMAP account. You should expect to experience data loss and other situations that could lead to the loss of valuable information. Furthermore, you cannot install this build over a previous installation and revert back or install a build with the old IMAP back-end over this build. This can cause serious corruption in the local storage and indexing of messages. We're releasing this now because we've reached the point in development where we need to test in a wider range of environments. There are still many issues we need to solve, but it's important to know if there are any design flaws. We have not yet decided if the new IMAP back-end will be included in Opera 8.0. Your feedback is essential in the decision-making process. We'll be maintaining a list of severe known issues, to prevent duplicate bug reports.
