"Perhaps the most notable changes are bug fixes for broken "mbox"
functionality, for a crash when Taking to a Rule, for a crash when Sorting
on some IMAP servers, and for a problem when forwarding address book
entries and Taking them, which caused remote address book corruption.
There is some new support for reading news from more than one NNTP server,
a new tab-checks-recent feature to allow checking for new mail in a folder
without opening it, and a few other small improvements."
