WebLight is a web testing tool that helps web developers maintain reliable sites by quickly locating broken links and non-standard HTML.
* Features a completely redesigned Diagnostics window.
The new design allows you to easily categorize diagnostics so you ignore problems that you don't care about and locate important problems faster.
* Does not by default collect CSS warnings.
If you want CSS warnings included in your diagnostics, check "Include diagnostics that may make more reliable stylesheets" on Preferences/CSS.
* Fixes problems resolving relative links in Atom feeds.
