• Autosave makes sure you never lose a post again.

• The lossless XML import and export makes it easy for you to move your content between WordPress blogs.

• Much more efficient database code, faster than previous versions. (We'd have to check how that compares with lightpress-queries..)

• Links in your blogroll now support sub-categories and you can add categories on the fly.

• Pages can now be drafts, or private.

• Better internationalization and support for right-to-left languages.

• A new version of the Akismet plugin is bundled.

You can go grab the update at wordpress.org but beware: Lightpress won't work with Wordpress > 2.0.x yet! Mainly this is because of the changes to the posts-table and the link-categories.

The posts-table now has a column named "post_type" (which can take 'post' or 'page') and one named 'post_status' which is the usual 'publish', 'draft' or 'private'. The link-categories have been merged into the global categories-table (PLUS, old link-categories get a new id!) and there is a new table called 'link2cat' linking between the two tables.

I'm working on a patch (since my site is already working with wp2.1RC2 and lp2 nightly) and i hope it won't be long.
