Breaking Changes

Validation Result Changes

Due to a bug fix, the Validation now might change the validation results when you validate an array item (see Changelog). So check the validation results for all the code that validates the array. Validating multiple fields like contacts.*.name is not affected.

If you have the following form:

<input type='text' name='invoice_rule[1]'>
<input type='text' name='invoice_rule[2]'>

And you have the validation rule like this:

'invoice_rule' =>  ['rules' => 'numeric', 'errors' => ['numeric' => 'Not numeric']]

Change the rule key to invoice_rule.* and the validation will work.

Breaking Enhancements


Project Files

Numerous files in the project space (root, app, public, writable) received updates. Due to these files being outside of the system scope they will not be changed without your intervention. There are some third-party CodeIgniter modules available to assist with merging changes to the project space: Explore on Packagist.


Except in very rare cases for bug fixes, no changes made to files for the project space will break your application. All changes noted here are optional until the next major version, and any mandatory changes will be covered in the sections above.
