This check used to be Off by +default, and required explicitly setting the **validate** option to ``TRUE`` +in order to enable it. + +Naturally, a validity check should not result in any problems, but this is +technically a backwards-compatibility break and you should check that +everything works fine. +If something indeed goes wrong with that, please report it as a bug to us, +and you can disable the **validate** option to revert to the old behavior. + +Step 7: Check usage of doctype() HTML helper +============================================ + +The :doc:`HTML Helper <../helpers/html_helper>` function +:php:func:`doctype()` used to default to 'xhtml1-strict' (XHTML 1.0 Strict) +when no document type was specified. That default value is now changed to +'html5', which obviously stands for the modern HTML 5 standard. + +Nothing should be really broken by this change, but if your application +relies on the default value, you should double-check it and either +explicitly set the desired format, or adapt your front-end to use proper +HTML 5 formatting. + +Step 8: Check usage of form_upload() Form helper +================================================ + +The :doc:`Form Helper <../helpers/form_helper>` function +:php:func:`form_upload()` used to have 3 parameters, the second of which +(``$value``) was never used, as it doesn't make sense for an HTML ``input`` +tag of the "file" type. + +That dead parameter is now removed, and so if you've used the third one +(``$extra``), having code like this:: + + form_upload('name', 'irrelevant value', $extra);
