 * (crypto/keyring) [#21653](https://github.com/cosmos/cosmos-sdk/pull/21653) New Linux-only backend that adds Linux kernel's `keyctl` support.
 * (runtime) [#21704](https://github.com/cosmos/cosmos-sdk/pull/21704) Add StoreLoader in simappv2.
 * (client/keys) [#21829](https://github.com/cosmos/cosmos-sdk/pull/21829) Add support for importing hex key using standard input.
+* (x/validate) [#21822](https://github.com/cosmos/cosmos-sdk/pull/21822) New module solely responsible for providing ante/post handlers and tx validators for v2. It can be extended by the app developer to provide extra tx validators.
+    * In comparison to x/auth/tx/config, there is no app config to skip ante/post handlers, as overwriting them in baseapp or not injecting the x/validate module has the same effect.

 ### API Breaking Changes
 
 * (types/mempool) [#21744](https://github.com/cosmos/cosmos-sdk/pull/21744) Update types/mempool.Mempool interface to take decoded transactions. This avoid to decode the transaction twice.
+* (x/auth/tx/config)  [#21822](https://github.com/cosmos/cosmos-sdk/pull/21822) Sign mode textual is no more automatically added to tx config when using runtime. Should be added manually on the server side.
+* (x/auth/tx/config)  [#21822](https://github.com/cosmos/cosmos-sdk/pull/21822) This depinject module now only provide txconfig and tx config options. `x/validate` now handles the providing of ante/post handlers, alongside tx validators for v2. The corresponding app config options have been removed from the depinject module config.

+Introducing `x/validate` a module that is solely used for registering default ante/post handlers and global tx validators when using runtime and runtime/v2. If you wish to set your custom ante/post handlers, no need to use this module.
+You can however always extend them by adding extra tx validators (see `x/validate` documentation).
