### Improvements
* (crypto/ledger) [#22116](https://github.com/cosmos/cosmos-sdk/pull/22116) Improve error message when deriving paths using index >100
* (sims) [#21613](https://github.com/cosmos/cosmos-sdk/pull/21613) Add sims2 framework and factory methods for simpler message factories in modules
* (modules) [#21963](https://github.com/cosmos/cosmos-sdk/pull/21963) Duplicatable metrics are no more collected in modules. They were unecessary overhead.
