Breaking Changes

As a major release, MODX 3.0 comes with a number of breaking changes. There is always a balance to be kept between breaking changes that cleanup technical debt, and not breaking things unnecessarily.

Most important breaking changes¶

The biggest breaking changes can be summarised as follows:

• Minimum supported PHP version has been increased to 7.2
• It's no longer possible to use a custom core folder/path
• sqlsrv support has been removed
• A large number of (previously unnamespaced) classes have been renamed and moved, including processors and model classes.
• All processors have been renamed, including base processors
• modAction and related functionality has been removed
• modRestClient has been removed #15781 and has been replaced with a new PSR-7/17/18 HTTP service

Legacy functionality cleanup¶

• modResource->contentType field has been removed; that was replaced in Revolution 2.0 with a content_type field that maps to a modContentType instance. #14057
• modParser095, modTranslate095, and modTranslator have been removed. Those were utilities for migrating templates from Evolution syntax. #14133
• /manager/min/ directory has been removed; was unused since 2.5. #12778, #13194, #14416
• Unused ExtJS grids have been removed: assets/modext/widgets/resource/modx.grid.resource.security.js, assets/modext/widgets/security/modx.grid.role.user.js, assets/modext/workspace/lexicon/language.grid.js, assets/modext/workspace/lexicon/lexicon.topic.grid.js #14895
• @EVAL binding has been removed from TVs #13865
