 * (crypto) [#15070](https://github.com/cosmos/cosmos-sdk/pull/15070) `GenerateFromPassword` and `Cost` from `bcrypt.go` now take a `uint32` instead of a `int` type.  
 * (x/capability) [#15344](https://github.com/cosmos/cosmos-sdk/pull/15344) Capability module was removed and is now housed in [IBC-GO](https://github.com/cosmos/ibc-go). 
 * [#15299](https://github.com/cosmos/cosmos-sdk/pull/15299) remove `StdTx` transaction and signing APIs. No SDK version has actually supported `StdTx` since before Stargate.
-* [#15600](https://github.com/cosmos/cosmos-sdk/pull/15600) add support for getting signers to `codec.Codec` and protoregistry support to `InterfaceRegistry`:
+* (codec) [#15600](https://github.com/cosmos/cosmos-sdk/pull/15600) add support for getting signers to `codec.Codec` and protoregistry support to `InterfaceRegistry`:
     * `Codec` is now a private interface and has the methods `InterfaceRegistry`, `GetMsgAnySigners`, `GetMsgV1Signers`, and `GetMsgV2Signers` which will fail when using `AminoCodec`.
      All implementations of `Codec` by other users must now embed an official implementation from the `codec` package.
     * `InterfaceRegistry` is now a private interface and implements `protodesc.Resolver` plus the `RangeFiles` method

 ### CLI Breaking Changes
 
+* (cli) [#15826](https://github.com/cosmos/cosmos-sdk/pull/15826) Remove `<appd> q account` command. Use `<appd> q auth account` instead.
 * (x/staking) [#14864](https://github.com/cosmos/cosmos-sdk/pull/14864) `create-validator` CLI command now takes a json file as an arg instead of having a bunch of required flags to it.
 * (cli) [#14659](https://github.com/cosmos/cosmos-sdk/pull/14659) `<app> q block <height>` is removed as it just output json. The new command allows either height/hash and is `<app> q block --type=height|hash <height|hash>`. 
 * (x/gov) [#14880](https://github.com/cosmos/cosmos-sdk/pull/14880) Remove `<app> tx gov submit-legacy-proposal cancel-software-upgrade` and `software-upgrade` commands. These commands are now in the `x/upgrade` module and using gov v1. Use `tx upgrade software-upgrade` instead.
