 Changelog
 =========
 
-- Add the ``docs.datasecurity.org`` preset
-- Add the ``voidtools.com`` preset
+- Rewrite preset system, so that the parsers are contained in a different repository, and they are loaded via a doctype.
+    - This will allow for faster and automatic preset updates, faster caching times, and it will reduce the strain on the hosts.
+- Remove the ``Use Cache`` option for non-api presets/doctypes.
+- Add a ``Cache Results`` option for doctype entries
