-BREAKING: The default Techdocs behavior will no longer attempt to copy `docs/README.md` or `README.md` to `docs/index.md` (if not found). To retain this behavior in your instance, you can set the following config in your `app-config.yaml`:
-
-```yaml
-techdocs:
-  generator:
-    mkdocs:
-      legacyCopyReadmeMdToIndexMd: true
-```
+Removed an undocumented, broken behavior where `README.md` files would be copied to `index.md` if it did not exist, leading to broken links in the TechDocs UI.
