I just recently attempted to upgrade from jQuery 1.2.6 to jQuery 1.3.2 and it broke several web pages where my selectors are escaping special characters - the period.
Here is a quick example: <input type="text" name="first.name" id="first.name"/> The selector $("#first\\.name") works in jQuery 1.2.6, but is broken in jQuery 1.3.2. Is this intentional or a is it a bug? I would be grateful if there is a workaround!
