Broken Link Checker - Version 0.9

Version Description

Masquerade as IE 7 when using the Snoopy library to check links. Should prevent some false positives.
Fixed relative URL handling (yet again). It'll work this time, honest ;)
Fixed post titles being displayed incorrectly on multilingual blogs (props Konstanin Zhilenko)
Misc fixes/comments.
"Unlink" works properly now.
Additional source code comments.
Don't try to display icons in email notifications. It didn't work anyway.
Use AJAX nonces for additional security.
General code cleanup.
Email notifications about broken links.
"Recheck" bulk action.
Check comment links.
Suspend checking if the server is overloaded (on by default).
Icons for broken links and redirects.
Fixed some UI glitches.
"Discard" gone, replaced by "Not broken".
"Exclude" gone from action links.
Better handling of false positives.
FTP, mailto:, javascript: and other links with unsupported protocols now show up in the All links list.

37	+ * "Edit URL" lets you change the URL of that link. If the link is present in more than one place (e.g. both in a post and in the blogroll) then all occurences of that URL will be changed.
38	* "Unlink" removes the link but leaves the link text intact.
39	+ * "Not broken" lets you manually mark a "broken" link as working. This is useful if you know it was incorrectly detected as broken due to a network glitch or a bug. The marked link will still be checked periodically, but the plugin won't consider it broken unless it gets a new result.
