 * (codec) [\#6330](https://github.com/cosmos/cosmos-sdk/pull/6330) `codec.RegisterCrypto` has been moved to the `crypto/codec` package and the global `codec.Cdc` Amino instance has been deprecated and moved to the `codec/legacy_global` package. 
 * (x/ibc) [\#6374](https://github.com/cosmos/cosmos-sdk/pull/6374) `VerifyMembership` and `VerifyNonMembership` now take a `specs []string` argument to specify the proof format used for verification. Most SDK chains can simply use `commitmenttypes.GetSDKSpecs()` for this argument.
 * (crypto/types/multisig) [\#6373](https://github.com/cosmos/cosmos-sdk/pull/6373) `multisig.Multisignature` has been renamed  to `AminoMultisignature`

+  * `NewAnteHandler` and `NewSigVerificationDecorator` both now take a `SignModeHandler` parameter.
+  * `SignatureVerificationGasConsumer` now has the signature: `func(meter sdk.GasMeter, sig signing.SignatureV2, params types.Params) error`.
+  * The `SigVerifiableTx` interface now has a `GetSignaturesV2() ([]signing.SignatureV2, error)` method and no longer has the `GetSignBytes` method.
