 ### API Breaking Changes
 
-* (simapp) [#12312](https:12278//github.com/cosmos/cosmos-sdk/pull/12312) Move `simapp.EmptyAppOptions` to `simtestutil.EmptyAppOptions` (`testutil/sims`)
-* (simapp) [#12312](https:12278//github.com/cosmos/cosmos-sdk/pull/12312) Remove `skipUpgradeHeights map[int64]bool` and `homePath string` from `NewSimApp` constructor as per migration of `x/upgrade` to app-wiring. 
-* (testutil) [#12278](https:12278//github.com/cosmos/cosmos-sdk/pull/12278) Move all functions from `simapp/helpers` to `testutil/sims`
+* (simapp) [#XXXXX](https://github.com/cosmos/cosmos-sdk/pull/XXXXX) Move `simapp.ConvertAddrsToValAddrs` and `simapp.CreateTestPubKeys ` to respectively `simtestutil.ConvertAddrsToValAddrs` and `simtestutil.CreateTestPubKeys` (`testutil/sims`)
+* (simapp) [#12312](https://github.com/cosmos/cosmos-sdk/pull/12312) Move `simapp.EmptyAppOptions` to `simtestutil.EmptyAppOptions` (`testutil/sims`)
+* (simapp) [#12312](https://github.com/cosmos/cosmos-sdk/pull/12312) Remove `skipUpgradeHeights map[int64]bool` and `homePath string` from `NewSimApp` constructor as per migration of `x/upgrade` to app-wiring. 
+* (testutil) [#12278](https://github.com/cosmos/cosmos-sdk/pull/12278) Move all functions from `simapp/helpers` to `testutil/sims`
 * (testutil) [#12233](https://github.com/cosmos/cosmos-sdk/pull/12233) Move `simapp.TestAddr` to `simtestutil.TestAddr` (`testutil/sims`)
 * (x/staking) [#12102](https://github.com/cosmos/cosmos-sdk/pull/12102) Staking keeper now is passed by reference instead of copy. Keeper's SetHooks no longer returns keeper. It updates the keeper in place instead.
 * (linting) [#12141](https://github.com/cosmos/cosmos-sdk/pull/12141) Fix usability related linting for database.  This means removing the infix Prefix from `prefix.NewPrefixWriter` and such so that it is `prefix.NewWriter` and making `db.DBConnection` and such into `db.Connection`
