+Nexy's magic changelog linkifier script! Linkify that changelog! Make it clickable!
+The masses LOVE being able to click things!
+
+Usage:
+
+    python3 bin/linkify-changelog.py
+
+Assumes CHANGELOG.md is in the current directory.
+Will not write if subsequent calls to linkify would change the output (to avoid nested linkification).
