I just looked at a project I’ve been working on, and it’s using 1.5.0 rc1. O_O

What will break if I upgrade now? Is 1.5.1 backwards compatible with code written for 1.5.0 rc1? I know I can read the change log but I’m hoping someone else has already done this and might save me the trouble by relating their experiences.

the use of $continue is no longer recommended and you will get an error msg telling you to use “return” instead.

Other than that, you should be fine, all the probs I have found have been worked out in the RC releases.

You no longer need json.js because Prototype has all the JSON methods you need.

supports JSON security measures too.

Ohh, one thing I did find is that Element.toggle( el1, el2, el3):
no longer works.

From their site:
In previous versions of Prototype, you could pass an arbitrary number of elements to Element.toggle,, and Element.hide, for consistency, this is no longer possible in version 1.5!

You can use:
$(‘content’, ‘navigation’, ‘footer’).invoke(‘hide’);

Great, thanks. Looks like I’ll have no problem at all migrating. :)
