Atto text editor

The Atto text editor will be removed from Moodle and replaced with TinyMCE. The text editor provides a set of buttons and functionalities that allow users to create content in a familiar way. The new editor will still provide similar functionalities and a similar experience.

The Atto editor is known to causes screen freezes when its on a paged when viewed on iOS devices.

A workaround is available by switching to the TinyMCE Editor.

Education Technology timeline for retiring Atto

Tthe TinyMCE editor will be the only offered text editor from Myplace 25/26, and subsequent versions, as:

  • Atto will not be available in Moodle 4.5,

  • Moodle 4.5 will be the target Moodle version for 2025/2026 Myplace service

  • known issues with iPad & iOS causing screen freezes

  • We will also consider making TinyMCE the default editor on all historic Myplace services (where it is available).

Moodle HQ timeline for retiring Atto (it may change)

From Moodle 4.1:

  • The default editor for new and existing installs is still Atto

  • The legacy version for TinyMCE (TinyMCE 3) is still available

  • TinyMCE 6 is available as an administrator setting, or user preference

Developers are working on creating and/or migrating plugins that were available for Atto to TinyMCE 6. We are planning to work on changes to make it easier to use native TinyMCE plugins too but these are not yet complete and our investigation is not complete.

From Moodle 4.2:

  • the legacy version of TinyMCE has been removed

  • TinyMCE 6 becomes the default editor for new installations of Moodle

  • there is no change to the default editor for existing installs

From Moodle 4.4:

  • TinyMCE 6 will become the default editor for existing installations

From Moodle 4.5:

  • Atto will be removed but can still be installed from the plugins database

From Moodle 4.6:

  • The underlying libraries that Atto uses are planned for removal and it will no longer be possible to use Atto at all.

What does it mean?

Myplace will still use the Atto editor until the end of the 24/25 academic year as the default as some of the functionalities are not yet available for TinyMCE.

We believe that Myplace will move to TinyMCE by the start of the 25/26 academic year. Please keep in mind that we may have to change our plans if any majoir issues arise with the Atto editor.
