 ## [Unreleased]
 
+## [v0.44.4](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.44.4) - 2021-11-25
+
 ### Improvements
 * (x/upgrade) [\#10532](https://github.com/cosmos/cosmos-sdk/pull/10532)  Add `keeper.DumpUpgradeInfoWithInfoToDisk` to include `Plan.Info` in the upgrade-info file.
+* (store) [\#10544](https://github.com/cosmos/cosmos-sdk/pull/10544) Use the new IAVL iterator structure which significantly improves iterator performance.
 
 ### Bug Fixes
 
 * [\#10414](https://github.com/cosmos/cosmos-sdk/pull/10414) Use `sdk.GetConfig().GetFullBIP44Path()` instead `sdk.FullFundraiserPath` to generate key
+* (bank) [\#10394](https://github.com/cosmos/cosmos-sdk/pull/10394) Fix: query account balance by ibc denom.
 * [\10608](https://github.com/cosmos/cosmos-sdk/pull/10608) Change the order of module migration by pushing x/auth to the end. Auth module depends on other modules and should be run last. We have updated the documentation to provide more details how to change module migration order. This is technically a breaking change, but only impacts updates between the upgrades with version change, hence migrating from the previous patch release doesn't cause new migration and doesn't break the state.

 This release introduces bug fixes and improvements on the Cosmos SDK v0.44 series.
 
-The main performance improvement concerns gRPC queries, which are now able to run concurrently on the node ([\#10045](https://github.com/cosmos/cosmos-sdk/pull/10045)). To benefit from this performance boost, make sure to send your gRPC queries to the gRPC server directly (default port `9090`) instead of using the Tendermint RPC [`abci_query` endpoint](https://docs.tendermint.com/master/rpc/#/ABCI/abci_query) (default port `26657`).
+SDK v0.44.0-v0.44.3 x/auth migration have a **vesting account bug**, which vanishes `delegated_vesting` field from `BaseVestingAccount`. Recovery, unfortunately, is complicated and either involves manually overwriting it or querying an old state.
+We had to change the order of module migration by pushing x/auth to the end. Auth module state depends on x/stake and should be run last. We have updated the documentation to provide more details how to change module migration order. This is technically a breaking change, but only impacts updates between the major version change, hence migrating from the previous patch release (0.44.x) doesn't cause new migration and doesn't break the state.
 
-This release notably also:
+Other bug fixes:
++ grpc-gateway query account balance by IBC denom had an incorrect endpoint (correct one is `"/cosmos/bank/v1beta1/balances/{address}/by_denom"`)
++ use `sdk.GetConfig().GetFullBIP44Path()` instead `sdk.FullFundraiserPath` to generate key - this correctly resets hdpath when running `app testnet`.
 
-- bumps Tendermint to [v0.34.14](https://github.com/tendermint/tendermint/releases/tag/v0.34.14).
-- bumps the `gin-gonic/gin` version to 1.7.0 to fix the upstream [security vulnerability](https://github.com/advisories/GHSA-h395-qcrw-5vmq).
-- adds a null guard with a user-friendly error message for possible nil `Amount` in tx fee `Coins`.
+This release enables Auto Download feature to Cosmovisor >= v1.0.0. Now, you will be able to use Auto Download with the latest Cosmovisor when you will plan the next upgrade to the next major release (v0.45.0),
 
-See the [Cosmos SDK v0.44.3 milestone](https://github.com/cosmos/cosmos-sdk/blob/v0.44.3/CHANGELOG.md) on our issue tracker for the exhaustive list of all changes.
+Finally, we updated the IAVL to it's latest version and take a benefit of the new IAVL iterator, which improves the iteration performance.
