[WIP] Added Phalcon\Validation for Phalcon\Mvc\Collection

CHANGELOG.md

@@ -6,6 +6,7 @@
 - Added the ability to set custom Resultset class returned by find() [#12166](https://github.com/phalcon/cphalcon/issues/12166)
 - Added the ability to clear appended and prepended title elements (Phalcon\Tag::appendTitle, Phalcon\Tag::prependTitle). Now you can use array to add multiple titles. For more details check [#12238](https://github.com/phalcon/cphalcon/issues/12238).
 - Added the ability to specify what empty means in the 'allowEmpty' option of the validators. Now it accepts as well an array specifying what's empty, for example ['', false]
+- Added the ability to use `Phalcon\Validation` with `Phalcon\Mvc\Collection`, deprecated `Phalcon\Mvc\Collection::validationHasFailed`
 
 # [3.0.4](https://github.com/phalcon/cphalcon/releases/tag/v3.0.4) (XXXX-XX-XX)
 - Fixed Isnull check is not correct when the model field defaults to an empty string. [#12507](https://github.com/phalcon/cphalcon/issues/12507)
