+Marked the field `spec.implementsApis` on `Component` entities for deprecation on Dec 14th, 2020.
+
+Code that consumes these fields should remove those usages as soon as possible and migrate to using
+relations instead. Producers should fill the field `spec.providesApis` instead, which has the same
+semantic.
+
+After Dec 14th, the fields will be removed from types and classes of the Backstage repository. At
+the first release after that, they will not be present in released packages either.
+
+If your catalog-info.yaml files still contain this field after the deletion, they will still be
+valid and your ingestion will not break, but they won't be visible in the types for consuming code, and the expected relations will not be generated based on them either.```
