 {productname} {release-version} also includes the following bug fix<es>:
 
-// === <TINY-vwxyz 1 changelog entry>
-// #TINY-vwxyz1
+=== Japanese keyboard could insert content while the editor was in `readonly` mode
+// #TINY-11363
 
-// CCFR here.
+In previous versions of {productname}, an issue was identified where the editor permitted content insertion via IME (Input Method Editor) input, such as using a Japanese keyboard even when the editor was configured with `readonly: true`. This behavior allowed users to bypass standard input restrictions, potentially compromising content protection and data integrity.
+
+With the release of {productname} {release-version}, this issue has been addressed by implementing event handlers that intercept and block IME-related input events and their default behaviors while in read-only mode. This enhancement ensures that the readonly setting is strictly enforced, preventing content modifications from all input sources, including IME. As a result, data integrity is preserved, and the editor's reliability in multilingual environments is significantly improved.
