 ### CLI Breaking Changes
 
-* [\#9695](https://github.com/cosmos/cosmos-sdk/pull/9695) `<app> keys migrate` CLI command now takes no arguments
+* (cli) [\#11818](https://github.com/cosmos/cosmos-sdk/pull/11818) CLI transactions preview now respect the chosen `--output` flag format (json or text)
+* [\#9695](https://github.com/cosmos/cosmos-sdk/pull/9695) `<app> keys migrate` CLI command now taks no arguments
 * [\#9246](https://github.com/cosmos/cosmos-sdk/pull/9246) Removed the CLI flag `--setup-config-only` from the `testnet` command and added the subcommand `init-files`.
 * [\#9780](https://github.com/cosmos/cosmos-sdk/pull/9780) Use sigs.k8s.io for yaml, which might lead to minor YAML output changes
 * [\#10625](https://github.com/cosmos/cosmos-sdk/pull/10625) Rename `--fee-account` CLI flag to `--fee-granter`
