New features

Multiple toolbars

For more information on multiple toolbars refer to the documentation.

Note: If multiple toolbars are used, the toolbar drawer will be disabled as toolbar drawers aren’t compatible with multiple toolbars.

base_url and suffix options

TinyMCE 5.0.9 adds two new configuration options: base_url and suffix. These new options provide an easier way to provide the editor manager baseURL and suffix properties.

For more information on the new options refer to the base_url and suffix documentation.

Media plugin m4a file support

The Media plugin now supports the M4A audio format. Inserting a m4a file will now be embedded using a HTML5 <audio> element.

For more information on the media plugin refer to the documentation.

Updates and enhancements


The new TinyMCE 5.0.9 editor comes with numerous changes to the previous versions. A comprehensive list of the updates and fixed issues is available in the changelog.

Iframe dialog component

The TinyMCE iframe dialog component has been changed to use the srcdoc attribute instead of the src attribute when sandboxing is enabled, which will allow the Origin header to be correctly sent to the server.

This resolves the issue with the previous release where cloud hosted Premium Skins and Icon packs failed to load in the Preview plugin dialog.

Space key not working in lists

TinyMCE 5.0.9 has addressed an issue where trying to press the space key at the end of a nested list may not have correctly inserted a space.

Legacy Output plugin

The Legacy Output plugin comes with numerous bug fixes and improvements. Issues have been addressed so that the correct font size will be shown in the font size selector, images can be center aligned and removing text colors will work as expected.

For more information on Legacy Output refer to the documentation.

Enhanced Media Embed

Enhanced Media Embed 2.2.1 has addressed an issue where pressing the enter key after multiple links, separated by <br> elements, could cause the links to disappear.

For more information on Enhanced Media Embed refer to the documentation.


LinkChecker 2.0.3 has addressed an issue where empty or blank links were incorrectly sent for validation and marked as invalid.

For more information on Link Checker refer to the documentation.
