+## Unreleased
+
+### New Features (BREAKING)
+
+- <csr-id-38319375d07ca5d09700d40a778c367564cd8a66/> Add support for detecting deleted crates.
+  Previously there was no need to do that as deletions couldn't happen -
+  crates are yanked instead.
+
+  Now that the ecosystem experienced its first (known) supply-chain attack
+  crates can also be deleted and we should be able to detect that to allow
+  downstream users to act on this automatically.
+
+### Bug Fixes
+
+ - <csr-id-d273245d99836ef799946373444a0b85e02523d0/> update version in usage example
