 # CHANGELOG
 
+## v0.13.0
+
+This release:
+- changes the contract of the Iterator Key() and Value() APIs: the caller
+is now responsible for creating a copy of their returned value if they want to modify it.
+- bumps the Go version to 1.22.5 (from 1.22). Go 1.22.5 does not introduce new language
+features, therefore code using older version will still compile. However, we recommend to
+upgrade to the latest version(s) of Go as soon as possible.
+
+
+### FEATURES
+
+- Iterator Key and Value APIs now return an object that must be copied before
+  use ([\#168](https://github.com/cometbft/cometbft-db/pull/168))
