Remove Active Support, release 2.1

 # Changelog
 
+## 2.1.0
+
+- Remove Active Support as a dependency
+  - This now provides rudimentary support of `html_safe` mechanics. Note that
+    it does NOT handle _any_ additional String methods. It simply allows cloning a string via `html_safe` to mark it safe, and `html_safe?` to query if it's safe.
+  - This _might_ be a breaking change, but likely not if you're using Serbea along with Rails or Bridgetown. To restore previous functionality manually, just install the `activesupport` gem and `require "active_support/core_ext/string/output_safety"` before you require the Serbea gem.
+
 ## 2.0.0
 
 - Add plain ol' Ruby pipeline functionality
