(module/core/02-client) #165 Remove GetFrozenHeight from the ClientState interface.
(modules) #166 Remove GetHeight from the misbehaviour interface. The consensus_height attribute has been removed from Misbehaviour events.
(modules) #162 Remove deprecated Handler types in core IBC and the ICS 20 transfer module.
(modules/core) #161 Remove Type(), Route(), GetSignBytes() from 02-client, 03-connection, and 04-channel messages.
(modules) #140 IsFrozen() client state interface changed to Status(). gRPC ClientStatus route added.

(modules/light-clients/07-tendermint) #141 Allow a new form of misbehaviour that proves counterparty chain breaks time monotonicity, automatically enforce monotonicity in UpdateClient and freeze client if monotonicity is broken.
(modules/light-clients/07-tendermint) #141 Freeze the client if there's a conflicting header submitted for an existing consensus state.

(modules/core/04-channel) #144 Introduced a packet_data_hex attribute to emit the hex-encoded packet data in events. This allows for raw binary (proto-encoded message) to be sent over events and decoded correctly on relayer. Original packet_data is DEPRECATED. All relayers and IBC event consumers are encouraged to switch to packet_data_hex as soon as possible.
