 ### Bug Fixes
 
+* (server) [#18537](https://github.com/cosmos/cosmos-sdk/pull/18537) Fix panic when defining minimum gas config as `100stake;100uatom`. Use a `,` delimiter instead of `;`. Fixes the server config getter to use the correct delimiter.
 * (client/tx) [#18472](https://github.com/cosmos/cosmos-sdk/pull/18472) Utilizes the correct Pubkey when simulating a transaction.
