+## v0.5.14
+
+This release contains wasmvm bugfix to prevent non-deterministic error messages comes out from wasmvm.

+- [\#635](https://github.com/terra-money/core/pull/635) bump wasmvm to v0.16.3
+
+## v0.5.13
+
+This release contains oracle tally bugfix, which was not sorting cross rate ballot before computing weighted median. It makes the cross rate selected quite randomly...
+
+This update will sort cross rate ballot before computing weighted median value.
+
+- [b073fb1](https://github.com/terra-money/core/commit/b073fb18e5107caee077f214b5fad4de53b055f5) sort cross rate ballot and enforce sorted before computing weighted median
+
 ## v0.5.12
 
 This release contains [IAVL bugfix](https://github.com/cosmos/iavl/pull/449)
