 ### Changelog
 
+- 2.4: CSS editor for Janitor profiles. New banner links to the live-preview editor at tools.from-avalon.com/janitor-profile-maker.
 - 2.3: ECHO. Put ECHO: anywhere in a message and sucker repeats whatever comes after it in the reply — for triggering char-side script and lorebook keywords.
 - 2.2: Added support for directly inputting webp file names or character image links when creating PNG character cards
 - 2.1: updated deps, note about image fetching, list of mirrors

+                  We&apos;d like to introduce a CSS editor we have been working
+                  on for Janitor profiles. It comes loaded with some simple
+                  presets, and we plan to include more in the future, be it
+                  ours or provided by the community. You can see changes occur
+                  in live time and it should accurately represent the
+                  behaviour of the CSS if used in your Janitor profile.
