I just released HTML_AJAX 0.2.1, if your running 0.2.0 you’ll want to upgrade immediatly since this fixes a bunch of bugs I added in that version.
The main changes are:
Remove debug message when throwing an exception
Fix problems with async calls
Fix broken content-type detection
Stop trying to run an init method when the init flag isn’t set
PHP required version moved to 4.1.0 which is what it should need
A basic debug class has been added, allowing you to write PHP errors to a file
HTML_AJAX.replace now works async
Also there is now a mailing list for HTML_AJAX.
