 ## Unreleased
 
+## [v0.42.10](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.42.10) - 2021-09-28
+
+### Improvements
+
+* (store) [\#10026](https://github.com/cosmos/cosmos-sdk/pull/10026) Improve CacheKVStore datastructures / algorithms, to no longer take O(N^2) time when interleaving iterators and insertions.
+* (store) [\#10040](https://github.com/cosmos/cosmos-sdk/pull/10040) Bump IAVL to v0.17.1 which includes performance improvements on a batch load.
+* [\#10211](https://github.com/cosmos/cosmos-sdk/pull/10211) Backport of the mechanism to reject redundant IBC transactions from [ibc-go \#235](https://github.com/cosmos/ibc-go/pull/235).
+
+### Bug Fixes
+
+* [\#9969](https://github.com/cosmos/cosmos-sdk/pull/9969) fix: use keyring in config for add-genesis-account cmd.
+
+### Client Breaking Changes
+
+* [\#9879](https://github.com/cosmos/cosmos-sdk/pull/9879) Modify ABCI Queries to use `abci.QueryRequest` Height field if it is non-zero, otherwise continue using context height.
+
+### API Breaking Changes
+
+* [\#10077](https://github.com/cosmos/cosmos-sdk/pull/10077) Remove telemetry on `GasKV` and `CacheKV` store Get/Set operations, significantly improving their performance.

Applications must now include the capability module in their BeginBlocker order before any module that uses capabilities gets run.

 ### API Breaking Changes
 
 * [\#9835](https://github.com/cosmos/cosmos-sdk/pull/9835) The `InitializeAndSeal` API has not changed, however it no longer initializes the in-memory state. `InitMemStore` has been introduced to serve this function, which will be called either in `InitChain` or `BeginBlock` (whichever is first after app start). Nodes may run this version on a network running 0.42.x, however, they must update their app.go files to include the capability module in their begin blockers.

 ### Improvements
 
+* (deps) [\#9956](https://github.com/cosmos/cosmos-sdk/pull/9956) Bump Tendermint to [v0.34.12](https://github.com/tendermint/tendermint/releases/tag/v0.34.12).
 * (cli) [\#9717](https://github.com/cosmos/cosmos-sdk/pull/9717) Added CLI flag `--output json/text` to `tx` cli commands.

-# Cosmos SDK v0.42.9 "Stargate" Release Notes
+# Cosmos SDK v0.42.10 "Stargate" Release Notes
 
-This release includes an important `x/capabiliy` module bug fix for 0.42.7 and 0.42.8 which prohibits IBC to create new channels (issuse [\#9800](https://github.com/cosmos/cosmos-sdk/issues/9800)).
-The fix changes the `x/capability/keeper/Keeper.InitializeAndSeal` method behavior and requires to update an app module manager by adding x/capability module to Begin Blockers.
+This release includes a new `AnteHandler` that rejects redundant IBC transactions to save relayers fees. This is a backport of [ibc-go \#235](https://github.com/cosmos/ibc-go/pull/235).
 
-We also fixed `<app> init --recovery` mode where the mnemonic was not handled correctly.
+v0.42.10 also includes multiple performance improvements, such as:
 
-We also changed `<app> tx distribution withdraw-all-rewards` CLI by forcing the broadcast mode if a chunk size is greater than 0. This will ensure that the transactions do not fail even if the user uses invalid broadcast modes for this command (sync and async). This was requested by the community and we consider it as fixing the `withdraw-all-rewards` behavior.
+- improve ABCI performance under concurrent load via [Tendermint v0.34.13](https://github.com/tendermint/tendermint/blob/master/CHANGELOG.md#v03413),
+- improve CacheKVStore datastructures / algorithms, to no longer take O(N^2) time when interleaving iterators and insertions.
+- bump IAVL to v0.17.1 which includes performance improvements on a batch load.
 
-See the [Cosmos SDK v0.42.9 milestone](https://github.com/cosmos/cosmos-sdk/milestone/53?closed=1) on our issue tracker for the exhaustive list of all changes.
+We fixed the keyring to use pre-configured data for `add-genesis-account` command.
+
+Finally, when using the `client.Context`, we modified ABCI queries to use `abci.QueryRequest`'s `Height` field if it is non-zero, otherwise continue using `client.Context`'s height. This is a minor client-breaking change for users of the `client.Context`.
