+#### Changed
+
+- From now on, themes can customise the activity icon colours using simple CSS variables. The new variables are $activity-icon-administration-bg, $activity-icon-assessment-bg, $activity-icon-collaboration-bg, $activity-icon-communication-bg, $activity-icon-content-bg, $activity-icon-interactivecontent-bg. All previous `$activity-icon-*-filter` elements can be removed, as they are no longer in use.

 #### Removed
 
 - Remove chat and survey styles. Important note: the styles have been moved to the plugins as CSS files (and not SCSS) so themes might now need to override the mod_chat and mod_survey styles specifically as css does not have any definition for primary, gray and other colors accessible in the original scss version.
