+To provide some stability to users of 0.X.X versions of Tendermint, the MINOR version is used

+publicly exposed types, functions, and methods in non-internal Go packages as well as
+the types and methods accessible via the Tendermint RPC interface.
 
-That said, breaking changes in the following packages will be documented in the
-CHANGELOG even if they don't lead to MINOR version bumps:
-
-- crypto
-- config
-- libs

-    - bytes
-    - json
-    - log
