 ### Changes
 
 * Removes postcss plugin and webpack loader used for breakpoint preview mode. Uses instead the new `postcss-viewport-to-container-toggle` plugin in the webpack config.
+* Implement `vue-color` directly in Apostrophe rather than as a dependency
+* Switch color handling library from `tinycolor2` to `@ctrl/tinycolor`
 * Removes error messages in server console for hidden fields. These messages should not have been printed out in the server console in the first place.
 * Removes invalid error messages on select fields appearing while opening an existing valid document.
