+# Your name.
+author: MattAtlas
+
+# Optional: Remove this file after generating master changelog.  Useful for PR changelogs that won't get used again.
+delete-after: True
+
+# Any changes you've made.  See valid prefix list above.
+# INDENT WITH TWO SPACES.  NOT TABS.  SPACES.
+# SCREW THIS UP AND IT WON'T WORK.
+# Also, all entries are changed into a single [] after a master changelog generation. Just remove the brackets when you add new entries.
+# Please surround your changes in  double quotes ("), as certain characters otherwise screws up compiling. The quotes will not show up in the changelog.
+changes:
+  - tweak: "Most common melee simple mobs have been given armor penetration, so they should actually have teeth now."
+  - tweak: "Melee simple mobs have also been given edge or sharp damage flags, so bleeding should be more common, in addition to torn tendons."
+  - tweak: "Hivebot beams have been buffed to account for new armor."
