 ### Improvements
 
+* (x/params) [#12615](https://github.com/cosmos/cosmos-sdk/pull/12615) Add `GetParamSetIfExists` function to params `Subspace` to prevent panics on breaking changes.
 * (x/bank) [#12674](https://github.com/cosmos/cosmos-sdk/pull/12674) Add convenience function `CreatePrefixedAccountStoreKey()` to construct key to access account's balance for a given denom.
