Remove TinyMCE from the upcoming 1.5.0

Posted by fiammybe on 1654175756

Currently no-one in the development team is using TinyMCE on their servers (we're more partial to CKEditor), and we need to do a major version update of TinyMCE because of a security issue in the editor.

If there is no-one that can assist with testing the newer version of TinyMCE, that editor will be removed from the core starting with ImpressCMS 1.5.0.
