 ## [2.1.0] - Unreleased
+* Breaking:
+  * SDK:
+    * `cargo-build-sbf` and `cargo-build-bpf` have been deprecated for two years and have now been definitely removed.
+       Use `cargo-build-sbf` and `cargo-test-sbf` instead.
 * Changes
   * SDK: removed the `respan` macro. This was marked as "internal use only" and was no longer used internally.
