Matrix 2.5.7 Released
We just released Matrix 2.5.7, which fixes some minor compatibility issues with EE 2.7, including Channel Form support for the built-in File cell type.
We’ve also added a new extension hook, “matrix_modify_field_data”, which can be used to customize your Matrix field’s data before it gets displayed on the Publish page. That’s useful if you want to write an extension that gives your Matrix field a default value, for example.
This is a recommended update for anyone who is using Matrix with EE 2.7+.
