[development] Module developers - please test your modules on 5.2-dev

[Heine Deelstra]

Dear module developers,

Please test your modules on Drupal 5.2-dev. It has a duplicate form submission filter
<http://drupal.org/node/107358#comment-204814> that may cause subtle issues with your
modules' form submissions.

This happens when the proper operation of your module requires or should support
subsequent submissions that have the same $_POST data.

The remedy is to set #skip_duplicate_check for your form, or the form that your module alters.

Regards,

Heine Deelstra
