 ## [Unreleased]
 
+### Added
+- Add `dry_run` configuration option to `stacks-signer` config toml. Dry run mode will
+  run the signer binary as if it were a registered signer. Instead of broadcasting
+  `StackerDB` messages, it logs `INFO` messages. Other interactions with the `stacks-node`
+  behave normally (e.g., submitting validation requests, submitting finished blocks). A
+  dry run signer will error out if the supplied key is actually a registered signer.
+
 ### Changed
 
 - Miner will include other transactions in blocks with tenure extend transactions (#5760)
