This version:

* adds an "Export OPML..." function that writes your list of subscriptions to an OPML XML file;

* reduces duplicates by reverting to identifying stories by URL instead of a hash of URL, date, and title when the feed doesn't provide unique IDs for its items; Forumzilla still uses a hash for feeds in "quick mode" (i.e. when you tell Forumzilla to show you "just the summary" via the advanced options section of the subscriptions dialog box);

* reduces duplicates by checking a few variations on URLs when using URLs to identify feeds; specifically, Forumzilla tries the URL with or without a trailing slash and "www." at the beginning of the hostname;

* supports the XML base attribute when added to the root element of an Atom feed;

* fixes a couple bugs when retrieving the timestamp and escaped HTML content of items in an Atom feed.

This version fixes minor incompatibilities with the latest development versions of Thunderbird, fixes a bug that caused the New Folder button in the subscriptions dialog not to work, changes the Feeds button icon to the standard feed icon, and fixes a number of other bugs.

this version works with Thunderbird 1.5
