+### Client Breaking
+
+- (x/auth) [\#6054](https://github.com/cosmos/cosmos-sdk/pull/6054) Remove custom JSON marshaling for base accounts as multsigs cannot be bech32 decoded.
+- (modules) [\#5572](https://github.com/cosmos/cosmos-sdk/pull/5572) The `/bank/balances/{address}` endpoint now returns all account
+  balances or a single balance by denom when the `denom` query parameter is present.
+- (client) [\#5640](https://github.com/cosmos/cosmos-sdk/pull/5640) The rest server endpoint `/swagger-ui/` is replaced by ´/´.
+- (x/auth) [\#5702](https://github.com/cosmos/cosmos-sdk/pull/5702) The `x/auth` querier route has changed from `"acc"` to `"auth"`.
+- (store/types) [\#5730](https://github.com/cosmos/cosmos-sdk/pull/5730) store.types.Cp() is removed in favour of types.CopyBytes().
+- (client) [\#5640](https://github.com/cosmos/cosmos-sdk/issues/5783) Unify all coins representations on JSON client requests for governance proposals.
+- [\#5785](https://github.com/cosmos/cosmos-sdk/issues/5785) JSON strings coerced to valid UTF-8 bytes at JSON marshalling time
+  are now replaced by human-readable expressions. This change can potentially break compatibility with all those client side tools
+  that parse log messages.
+- (client) [\#5799](https://github.com/cosmos/cosmos-sdk/pull/5799) The `tx encode/decode` commands, due to change on encoding break compatibility with
+  older clients.
+- (x/auth) [\#5844](https://github.com/cosmos/cosmos-sdk/pull/5844) `tx sign` command now returns an error when signing is attempted with offline/multisig keys.
+- (x/auth) [\#6108](https://github.com/cosmos/cosmos-sdk/pull/6108) `tx sign` command's `--validate-signatures` flag is migrated into a `tx validate-signatures` standalone command.
+- (client/keys) [\#5889](https://github.com/cosmos/cosmos-sdk/pull/5889) Remove `keys update` command.
+- (x/evidence) [\#5952](https://github.com/cosmos/cosmos-sdk/pull/5952) Remove CLI and REST handlers for querying `x/evidence` parameters.
+- (server) [\#5982](https://github.com/cosmos/cosmos-sdk/pull/5982) `--pruning` now must be set to `custom` if you want to customise the granular options.
+
+### API Breaking Changes
+
+- [\#6212](https://github.com/cosmos/cosmos-sdk/pull/6212) Remove `Get*` prefixes from key construction functions
+- [\#6079](https://github.com/cosmos/cosmos-sdk/pull/6079) Remove `UpgradeOldPrivValFile` (deprecated in Tendermint Core v0.28).
+- (modules) [\#5664](https://github.com/cosmos/cosmos-sdk/pull/5664) Remove amino `Codec` from simulation `StoreDecoder`, which now returns a function closure in order to unmarshal the key-value pairs.
+- (x/auth) [\#6029](https://github.com/cosmos/cosmos-sdk/pull/6029) Module accounts have been moved from `x/supply` to `x/auth`.
+- (x/supply) [\#6010](https://github.com/cosmos/cosmos-sdk/pull/6010) All `x/supply` types and APIs have been moved to `x/bank`.
+- (baseapp) [\#5865](https://github.com/cosmos/cosmos-sdk/pull/5865) The `SimulationResponse` returned from tx simulation is now JSON encoded instead of Amino binary.
+- [\#5719](https://github.com/cosmos/cosmos-sdk/pull/5719) Bump Go requirement to 1.14+
+- (x/params) [\#5619](https://github.com/cosmos/cosmos-sdk/pull/5619) The `x/params` keeper now accepts a `codec.Marshaller` instead of
+  a reference to an amino codec. Amino is still used for JSON serialization.
+- (types) [\#5579](https://github.com/cosmos/cosmos-sdk/pull/5579) The `keepRecent` field has been removed from the `PruningOptions` type.
+  The `PruningOptions` type now only includes fields `KeepEvery` and `SnapshotEvery`, where `KeepEvery`
+  determines which committed heights are flushed to disk and `SnapshotEvery` determines which of these
+  heights are kept after pruning. The `IsValid` method should be called whenever using these options. Methods
+  `SnapshotVersion` and `FlushVersion` accept a version arugment and determine if the version should be
+  flushed to disk or kept as a snapshot. Note, `KeepRecent` is automatically inferred from the options
+  and provided directly the IAVL store.
+- (modules) [\#5555](https://github.com/cosmos/cosmos-sdk/pull/5555) Move `x/auth/client/utils/` types and functions to `x/auth/client/`.
+- (modules) [\#5572](https://github.com/cosmos/cosmos-sdk/pull/5572) Move account balance logic and APIs from `x/auth` to `x/bank`.
+- (types) [\#5533](https://github.com/cosmos/cosmos-sdk/pull/5533) Refactored `AppModuleBasic` and `AppModuleGenesis`
+  to now accept a `codec.JSONMarshaler` for modular serialization of genesis state.
+- (types/rest) [\#5779](https://github.com/cosmos/cosmos-sdk/pull/5779) Drop unused Parse{Int64OrReturnBadRequest,QueryParamBool}() functions.
+- (keys) [\#5820](https://github.com/cosmos/cosmos-sdk/pull/5820/) Removed method CloseDB from Keybase interface.
+- (baseapp) [\#5837](https://github.com/cosmos/cosmos-sdk/issues/5837) Transaction simulation now returns a `SimulationResponse` which contains the `GasInfo` and
+  `Result` from the execution.
+- (client/input) [\#5904](https://github.com/cosmos/cosmos-sdk/pull/5904) Removal of unnecessary `GetCheckPassword`, `PrintPrefixed` functions.
+- (client/keys) [\#5889](https://github.com/cosmos/cosmos-sdk/pull/5889) Rename `NewKeyBaseFromDir()` -> `NewLegacyKeyBaseFromDir()`.
+- (crypto) [\#5880](https://github.com/cosmos/cosmos-sdk/pull/5880) Merge `crypto/keys/mintkey` into `crypto`.
+- (crypto/hd) [\#5904](https://github.com/cosmos/cosmos-sdk/pull/5904) `crypto/keys/hd` moved to `crypto/hd`.
+- (crypto/keyring):
+  - [\#5866](https://github.com/cosmos/cosmos-sdk/pull/5866) Rename `crypto/keys/` to `crypto/keyring/`.
+  - [\#5904](https://github.com/cosmos/cosmos-sdk/pull/5904) `Keybase` -> `Keyring` interfaces migration. `LegacyKeybase` interface is added in order
+    to guarantee limited backward compatibility with the old Keybase interface for the sole purpose of migrating keys across the new keyring backends. `NewLegacy`
+    constructor is provided [\#5889](https://github.com/cosmos/cosmos-sdk/pull/5889) to allow for smooth migration of keys from the legacy LevelDB based implementation
+    to new keyring backends. Plus, the package and the new keyring no longer depends on the sdk.Config singleton. Please consult the package documentation for more
+    information on how to implement the new `Keyring` interface.
+  - [\#5858](https://github.com/cosmos/cosmos-sdk/pull/5858) Make Keyring store keys by name and address's hexbytes representation.
+- (x/evidence) [\#5952](https://github.com/cosmos/cosmos-sdk/pull/5952) Remove APIs for getting and setting `x/evidence` parameters. `BaseApp` now uses a `ParamStore` to manage Tendermint consensus parameters which is managed via the `x/params` `Substore` type.
+- (export) [\#5952](https://github.com/cosmos/cosmos-sdk/pull/5952) `AppExporter` now returns ABCI consensus parameters to be included in marshaled exported state. These parameters must be returned from the application via the `BaseApp`.
+

+
+### State Machine Breaking
+
+- (x/staking) [\#6061](https://github.com/cosmos/cosmos-sdk/pull/6061) Allow a validator to immediately unjail when no signing info is present due to
+  falling below their minimum self-delegation and never having been bonded. The validator may immediately unjail once they've met their minimum self-delegation.
+- (x/supply) [\#6010](https://github.com/cosmos/cosmos-sdk/pull/6010) Removed the `x/supply` module by merging the existing types and APIs into the `x/bank` module.

+  - Account balances are now persisted and retrieved via the `x/bank` module.
+  - Vesting account interface has been modified to account for changes.
+  - Callers to `NewBaseVestingAccount` are responsible for verifying account balance in relation to
+    the original vesting amount.
+  - The `SendKeeper` and `ViewKeeper` interfaces in `x/bank` have been modified to account for changes.
+- (x/staking) [\#5600](https://github.com/cosmos/cosmos-sdk/pull/5600) Migrate the `x/staking` module to use Protocol Buffers for state
+  serialization instead of Amino. The exact codec used is `codec.HybridCodec` which utilizes Protobuf for binary encoding and Amino
+  for JSON encoding.
+  - `BondStatus` is now of type `int32` instead of `byte`.
+  - Types of `int16` in the `Params` type are now of type `int32`.
+  - Every reference of `crypto.Pubkey` in context of a `Validator` is now of type string. `GetPubKeyFromBech32` must be used to get the `crypto.Pubkey`.
+  - The `Keeper` constructor now takes a `codec.Marshaler` instead of a concrete Amino codec. This exact type
+    provided is specified by `ModuleCdc`.
+- (x/slashing) [\#5627](https://github.com/cosmos/cosmos-sdk/pull/5627) Migrate the `x/slashing` module to use Protocol Buffers for state
+  serialization instead of Amino. The exact codec used is `codec.HybridCodec` which utilizes Protobuf for binary encoding and Amino
+  for JSON encoding.
+  - The `Keeper` constructor now takes a `codec.Marshaler` instead of a concrete Amino codec. This exact type
+    provided is specified by `ModuleCdc`.

+  serialization instead of Amino. The exact codec used is `codec.HybridCodec` which utilizes Protobuf for binary encoding and Amino
+  for JSON encoding.
+  - `ValidatorHistoricalRewards.ReferenceCount` is now of types `uint32` instead of `uint16`.
+  - `ValidatorSlashEvents` is now a struct with `slashevents`.
+  - `ValidatorOutstandingRewards` is now a struct with `rewards`.
+  - `ValidatorAccumulatedCommission` is now a struct with `commission`.
+  - The `Keeper` constructor now takes a `codec.Marshaler` instead of a concrete Amino codec. This exact type
+    provided is specified by `ModuleCdc`.
+- (x/auth) [\#5533](https://github.com/cosmos/cosmos-sdk/pull/5533) Migrate the `x/auth` module to use Protocol Buffers for state
+  serialization instead of Amino.
+  - The `BaseAccount.PubKey` field is now represented as a Bech32 string instead of a `crypto.Pubkey`.
+  - `NewBaseAccountWithAddress` now returns a reference to a `BaseAccount`.
+  - The `x/auth` module now accepts a `Codec` interface which extends the `codec.Marshaler` interface by
+    requiring a concrete codec to know how to serialize accounts.
+  - The `AccountRetriever` type now accepts a `Codec` in its constructor in order to know how to
+    serialize accounts.
+- (x/supply) [\#5533](https://github.com/cosmos/cosmos-sdk/pull/5533) Migrate the `x/supply` module to use Protocol Buffers for state
+  serialization instead of Amino.
+  - The `internal` sub-package has been removed in order to expose the types proto file.
+  - The `x/supply` module now accepts a `Codec` interface which extends the `codec.Marshaler` interface by
+    requiring a concrete codec to know how to serialize `SupplyI` types.
+  - The `SupplyI` interface has been modified to no longer return `SupplyI` on methods. Instead the
+    concrete type's receiver should modify the type.
+- (x/mint) [\#5634](https://github.com/cosmos/cosmos-sdk/pull/5634) Migrate the `x/mint` module to use Protocol Buffers for state
+  serialization instead of Amino.
+  - The `internal` sub-package has been removed in order to expose the types proto file.
+- (x/evidence) [\#5634](https://github.com/cosmos/cosmos-sdk/pull/5634) Migrate the `x/evidence` module to use Protocol Buffers for state
+  serialization instead of Amino.
+  - The `internal` sub-package has been removed in order to expose the types proto file.
+  - The module now accepts a `Codec` interface which extends the `codec.Marshaler` interface by
+    requiring a concrete codec to know how to serialize `Evidence` types.
+  - The `MsgSubmitEvidence` message has been removed in favor of `MsgSubmitEvidenceBase`. The application-level
+    codec must now define the concrete `MsgSubmitEvidence` type which must implement the module's `MsgSubmitEvidence`
+    interface.
+- (x/upgrade) [\#5659](https://github.com/cosmos/cosmos-sdk/pull/5659) Migrate the `x/upgrade` module to use Protocol
+  Buffers for state serialization instead of Amino.
+  - The `internal` sub-package has been removed in order to expose the types proto file.
+  - The `x/upgrade` module now accepts a `codec.Marshaler` interface.
+- (x/gov) [\#5737](https://github.com/cosmos/cosmos-sdk/pull/5737) Migrate the `x/gov` module to use Protocol
+  Buffers for state serialization instead of Amino.
+  - `MsgSubmitProposal` will be removed in favor of the application-level proto-defined `MsgSubmitProposal` which
+    implements the `MsgSubmitProposalI` interface. Applications should extend the `NewMsgSubmitProposalBase` type
+    to define their own concrete `MsgSubmitProposal` types.
+  - The module now accepts a `Codec` interface which extends the `codec.Marshaler` interface by
+    requiring a concrete codec to know how to serialize `Proposal` types.
+- (codec) [\#5799](https://github.com/cosmos/cosmos-sdk/pull/5799) Now we favor the use of `(Un)MarshalBinaryBare` instead of `(Un)MarshalBinaryLengthPrefixed` in all cases that are not needed.
+- (x/evidence) [\#5952](https://github.com/cosmos/cosmos-sdk/pull/5952) Remove parameters from `x/evidence` genesis and module state. The `x/evidence` module now solely uses Tendermint consensus parameters to determine of evidence is valid or not.
+
+### Improvements
+
+- (baseapp) [\#6186](https://github.com/cosmos/cosmos-sdk/issues/6186) Support emitting events during `AnteHandler` execution.
+- (x/auth) [\#5702](https://github.com/cosmos/cosmos-sdk/pull/5702) Add parameter querying support for `x/auth`.
+- (types) [\#5581](https://github.com/cosmos/cosmos-sdk/pull/5581) Add convenience functions {,Must}Bech32ifyAddressBytes.
+- (staking) [\#5584](https://github.com/cosmos/cosmos-sdk/pull/5584) Add util function `ToTmValidator` that converts a `staking.Validator` type to `*tmtypes.Validator`.
+- (client) [\#5585](https://github.com/cosmos/cosmos-sdk/pull/5585) IBC additions:
+  - Added `prove` flag for commitment proof verification.
+  - Added `queryABCI` function that returns the full `abci.ResponseQuery` with inclusion merkle proofs.
+- (types) [\#5585](https://github.com/cosmos/cosmos-sdk/pull/5585) IBC additions:
+  - `Coin` denomination max lenght has been increased to 32.
+  - Added `CapabilityKey` alias for `StoreKey` to match IBC spec.
+- (server) [\#5709](https://github.com/cosmos/cosmos-sdk/pull/5709) There are two new flags for pruning, `--pruning-keep-every`
+  and `--pruning-snapshot-every` as an alternative to `--pruning`. They allow to fine tune the strategy for pruning the state.
+- (client) [\#5810](https://github.com/cosmos/cosmos-sdk/pull/5810) Added a new `--offline` flag that allows commands to be executed without an
+  internet connection. Previously, `--generate-only` served this purpose in addition to only allowing txs to be generated. Now, `--generate-only` solely
+  allows txs to be generated without being broadcasted and disallows Keybase use and `--offline` allows the use of Keybase but does not allow any
+  functionality that requires an online connection.
+- (types/module) [\#5724](https://github.com/cosmos/cosmos-sdk/issues/5724) The `types/module` package does no longer depend on `x/simulation`.
+- (client) [\#5856](https://github.com/cosmos/cosmos-sdk/pull/5856) Added the possibility to set `--offline` flag with config command.
+- (client) [\#5895](https://github.com/cosmos/cosmos-sdk/issues/5895) show config options in the config command's help screen.

+- (x/evidence) [\#5952](https://github.com/cosmos/cosmos-sdk/pull/5952) Tendermint Consensus parameters can now be changed via parameter change proposals through `x/gov`.
+- (x/evidence) [\#5961](https://github.com/cosmos/cosmos-sdk/issues/5961) Add `StoreDecoder` simulation for evidence module.
+- (x/auth/ante) [\#6040](https://github.com/cosmos/cosmos-sdk/pull/6040) `AccountKeeper` interface used for `NewAnteHandler` and handler's decorators to add support of using custom `AccountKeeper` implementations.
+- (simulation) [\#6002](https://github.com/cosmos/cosmos-sdk/pull/6002) Add randomized consensus params into simulation.
+- (x/staking) [\#6059](https://github.com/cosmos/cosmos-sdk/pull/6059) Updated `HistoricalEntries` parameter default to 100.
+- (x/ibc) [\#5948](https://github.com/cosmos/cosmos-sdk/issues/5948) Add `InitGenesis` and `ExportGenesis` functions for `ibc` module.
+- (types) [\#6128](https://github.com/cosmos/cosmos-sdk/pull/6137) Add `String()` method to `GasMeter`.
+- (types) [\#6195](https://github.com/cosmos/cosmos-sdk/pull/6195) Add codespace to broadcast(sync/async) response.
