IMAP-IDLE 1.07 pre 2 is available here. This version builds on 1.07 pre 1, providing:

• bug fixes (more stability)
• better recovery from loss of network
• better wake-from-sleep behavior

It also has a currently-useless preference for "periodic mailbox sync". The idea is to make mail do a sync of each account's mailboxes on a custom schedule determined by you, the user. At the moment, poking mail to sync causes it to beachball, so I''ve not yet figured out how to properly use that part of the API. Thus, you can set the "sync" preference all you want, but it doesn't do anything.

I've been running this version on two Intel macs for a couple of days without incident.

Post issues in the comments!

My last release was version 1.05, in November. I'm still working on the next version. I've gotten a number of helpful bug reports from people, some feature requests, and a suggestion that I make a fixed web page for IMAP-IDLE, rather than doing releases on my blog.
