This method is used to check if a `types.Coin` is greater than another `types.Coin`. * [#24071](https://github.com/cosmos/cosmos-sdk/pull/24071) (client/keys) Add support for importing hex key using standard input. * [#23780](https://github.com/cosmos/cosmos-sdk/pull/23780) (types) Add a ValueCodec for the math.Uint type that can be used in collections maps. * [#24045](https://github.com/cosmos/cosmos-sdk/pull/24045) (perf) Sims: Replace runsim command with Go stdlib testing. CLI: `Commit` default true, `Lean`, `SimulateEveryOperation`, `PrintAllInvariants`, `DBBackend` params removed * [#24040](https://github.com/cosmos/cosmos-sdk/pull/24040) (crypto/keyring) Expose the db keyring used in the keystore. * [#23919](https://github.com/cosmos/cosmos-sdk/pull/23919) (types) Add MustValAddressFromBech32 function. * [#23708](https://github.com/cosmos/cosmos-sdk/pull/23708) (all) Add unordered transaction support. * Adds a `--timeout-timestamp` flag that allows users to specify a block time at which the unordered transactions should expire from the mempool. * [#23815](https://github.com/cosmos/cosmos-sdk/pull/23815) (x/epochs) Upstream `x/epochs` from Osmosis * [#23811](https://github.com/cosmos/cosmos-sdk/pull/23811) (client) Add auto cli for node service. * [#24018](https://github.com/cosmos/cosmos-sdk/pull/24018) (genutil) Allow manually setting the consensus key type in genesis * [#18557](https://github.com/cosmos/cosmos-sdk/pull/18557) (client) Add `--qrcode` flag to `keys show` command to support displaying key address QR code. * [#24030](https://github.com/cosmos/cosmos-sdk/pull/24030) (x/auth) Allow usage of ed25519 keys for transaction signing. * [#24163](https://github.com/cosmos/cosmos-sdk/pull/24163) (baseapp) Add `StreamingManager` to baseapp to extend the abci listeners. * [#23933](https://github.com/cosmos/cosmos-sdk/pull/23933) (x/protocolpool) Add x/protocolpool module. * x/distribution can now utilize an externally managed community pool. NOTE: this will make the message handlers for FundCommunityPool and CommunityPoolSpend error, as well as the query handler for CommunityPool. * [#18101](https://github.com/cosmos/cosmos-sdk/pull/18101) (client) Add a `keyring-default-keyname` in `client.toml` for specifying a default key name, and skip the need to use the `--from` flag when signing transactions. * [#24355](https://github.com/cosmos/cosmos-sdk/pull/24355) (x/gov) Allow users to set a custom CalculateVoteResultsAndVotingPower function to be used in govkeeper.Tally. * [#24436](https://github.com/cosmos/cosmos-sdk/pull/24436) (x/mint) Allow users to set a custom minting function used in the `x/mint` begin blocker. * The `InflationCalculationFn` argument to `mint.NewAppModule()` is now ignored and must be nil. To set a custom `InflationCalculationFn` for the default minter, use `mintkeeper.WithMintFn(mintkeeper.DefaultMintFn(customInflationFn))`. * [#24428](https://github.com/cosmos/cosmos-sdk/pull/24428) (api) Add block height to response headers ## IMPROVEMENTS * [#24561](https://github.com/cosmos/cosmos-sdk/pull/24561) (client) TimeoutTimestamp flag has been changed to TimeoutDuration, which now sets the timeout timestamp of unordered transactions to the current time + duration passed. * [#24541](https://github.com/cosmos/cosmos-sdk/pull/24541) (telemetry) Telemetry now includes a pre\_blocker metric key. x/upgrade should migrate to this key in v0.54.0. * [#24541](https://github.com/cosmos/cosmos-sdk/pull/24541) (x/auth) x/auth's PreBlocker now emits telemetry under the pre\_blocker metric key. * [#24431](https://github.com/cosmos/cosmos-sdk/pull/24431) (x/bank) Reduce the number of `ValidateDenom` calls in `bank.SendCoins` and `Coin`. * The `AmountOf()` method on `sdk.Coins` will no longer `panic` if given an invalid denom and will instead return a zero value. * [#24391](https://github.com/cosmos/cosmos-sdk/pull/24391) (x/staking) Replace panics with error results; more verbose error messages * [#24354](https://github.com/cosmos/cosmos-sdk/pull/24354) (x/staking) Optimize validator endblock by reducing bech32 conversions, resulting in significant performance improvement * [#18950](https://github.com/cosmos/cosmos-sdk/pull/18950) (client/keys) Improve ` keys add`, ` keys import` and ` keys rename` by checking name validation. * [#18703](https://github.com/cosmos/cosmos-sdk/pull/18703) (client/keys) Improve ` keys add` and ` keys show` by checking whether there are duplicate keys in the multisig case. * [#18745](https://github.com/cosmos/cosmos-sdk/pull/18745) (client/keys) Improve ` keys export` and ` keys mnemonic` by adding --yes option to skip interactive confirmation. * [#24106](https://github.com/cosmos/cosmos-sdk/pull/24106) (x/bank) `SendCoins` now checks for `SendRestrictions` before instead of after deducting coins using `subUnlockedCoins`. * [#24036](https://github.com/cosmos/cosmos-sdk/pull/24036) (crypto/ledger) Improve error message when deriving paths using index > 100 * [#23844](https://github.com/cosmos/cosmos-sdk/pull/23844) (gRPC) Add debug log prints for each gRPC request. * [#24073](https://github.com/cosmos/cosmos-sdk/pull/24073) (gRPC) Adds error handling for out-of-gas panics in grpc query handlers. * [#24072](https://github.com/cosmos/cosmos-sdk/pull/24072) (server) Return BlockHeader by shallow copy in server Context. * [#24053](https://github.com/cosmos/cosmos-sdk/pull/24053) (x/bank) Resolve a foot-gun by swapping send restrictions check in `InputOutputCoins` before coin deduction. * [#24336](https://github.com/cosmos/cosmos-sdk/pull/24336) (codec/types) Most types definitions were moved to `github.com/cosmos/gogoproto/types/any` with aliases to these left in `codec/types` so that there should be no breakage to existing code. This allows protobuf generated code to optionally reference the SDK's custom `Any` type without a direct dependency on the SDK. This can be done by changing the `protoc` `M` parameter for `any.proto` to `Mgoogle/protobuf/any.proto=github.com/cosmos/gogoproto/types/any`. ## BUG FIXES * [#24460](https://github.com/cosmos/cosmos-sdk/pull/24460) (x/gov) Do not call Remove during Walk in defaultCalculateVoteResultsAndVotingPower. * (baseapp) [24261](https://github.com/cosmos/cosmos-sdk/pull/24261) Fix post handler error always results in code 1 * [#24068](https://github.com/cosmos/cosmos-sdk/pull/24068) (server) Allow aligning block header with skip check header in gRPC server. * [#24044](https://github.com/cosmos/cosmos-sdk/pull/24044) (x/gov) Fix some places in which we call Remove inside a Walk (x/gov). * [#24042](https://github.com/cosmos/cosmos-sdk/pull/24042) (baseapp) Fixed a data race inside BaseApp.getContext, found by end-to-end (e2e) tests. * [#24059](https://github.com/cosmos/cosmos-sdk/pull/24059) (client/server) Consistently set viper prefix in client and server.
