# Fatcat Production Import CHANGELOG

This file tracks major content (metadata) imports to the Fatcat production
database (at https://fatcat.wiki). It complements the code CHANGELOG file.

In general, changes that impact more than 50k entities will get logged here;
this file should probably get merged into the guide at some point.

This file should not turn in to a TODO list!
