Overview
TinyMCE 8.9.2 was released for TinyMCE Enterprise and Tiny Cloud on Wednesday, September 23rd, 2026. These release notes provide an overview of the changes for TinyMCE 8.9.2, including:
Accompanying Premium plugin changes
The following premium plugin updates were released alongside TinyMCE 8.9.2.
Revision History
The TinyMCE 8.9.2 release includes an accompanying release of the Revision History premium plugin.
Revision History includes the following fix.
The diff API would show identical tables as a replacement due to whitespace in the input strings
Previously, the diff API compared the two HTML strings exactly as supplied. When the strings contained whitespace characters, for example, indentation, the API could produce an unexpected result. Specifically, identical strings containing an indented table in HTML were reported as a replacement instead of as unchanged content.
In TinyMCE 8.9.2, the diff API normalizes both strings before comparing them. Fragments that render identically, regardless of the whitespace used to format the HTML, are now reported as unchanged.

Spell Checker
The TinyMCE 8.9.2 release includes an accompanying release of the Spell Checker premium plugin.
Spell Checker includes the following fix.
Could not apply a suggestion from the context menu while the dialog was open
Previously, choosing a spelling suggestion from the context menu had no effect while the Spell Checker dialog was open. Closing the dialog discarded the stored suggestions before the plugin could apply the selected one, so the misspelled word remained unchanged.
In TinyMCE 8.9.2, the Spell Checker plugin retains the suggestions long enough to apply the selection. Choosing a suggestion from the context menu now replaces the misspelled word.
