Permalinks Migration is a handy plugin for WordPress that will allow you to change your permalink structure without breaking any old links to your website and without affecting your search engine rankings.

It does this by generating a Permanent Redirect when a user or spider visits your site through your old permalinks which redirects the visitor to the new permalinks.

Good permalink structure can help you improve your search engine rankings, so if you would like to update your permalink structure, you can now do so quickly and easily!

If you upgraded to WordPress 2.1.1 in the past 3-4 days, download the new version (2.1.2) and update your blog again because your files may include a security exploit that was added by a cracker!

Only WordPress 2.1.1 seems to have been affected, so if you have not upgraded to WordPress 2.1.1 you should be fine. If your blog is running 2.1.1, please upgrade immediately and do a full overwrite of your old files.

For further details check out the WordPress blog.
