-# Cosmos SDK v0.44.5 Release Notes
+# Cosmos SDK v0.45.0 Release Notes
 
-This release introduces bug fixes and improvements on the Cosmos SDK v0.44 series:
+Cosmos SDK v0.45.0 is a logical continuation of the v0.44.\* series, but brings a couple of state- and API-breaking changes requested by the community.
 
-- Emit ante handler events for failed transactions: ant events can cause blockchain change (eg tx fees) and related events should be emitted.
-- (fix) Upgrade IAVL to 0.17.3 to solve race condition bug in IAVL.
+### State-Breaking Changes
 
-See the [Cosmos SDK v0.44.5 Changelog](https://github.com/cosmos/cosmos-sdk/blob/v0.44.5/CHANGELOG.md) for the exhaustive list of all changes.
+There are few important changes in **gas consumption**, which improve the gas economics:
 
-**Full Changelog**: https://github.com/cosmos/cosmos-sdk/compare/v0.44.4...v0.44.5
+- We now charge gas in two new places: on `.Seek()` even if there are no entries, and for the key length (on top of the value length).
+- When block gas limit is exceeded, we consume the maximum gas possible (to charge for the performed computation). We also fixed the bug when the last transaction in a block exceeds the block gas limit, it returns an error result, but the tx is actually committed successfully.
+
+Finally, a small improvement in gov, we increased the maximum proposal description size from 5k characters to 10k characters.
+
+### API-Breaking Changes
+
+- The `BankKeeper` interface has a new `HasSupply` method to ensure that input denom actually exists on chain.
+- The `CommitMultiStore` interface contains a new `SetIAVLCacheSize` method for a configurable IAVL cache size.
+- `AuthKeeper` interface in `x/auth` now includes a function `HasAccount`.
+
+Finally, when using the `SetOrder*` functions in simapp, e.g. `SetOrderBeginBlocker`, we now require that all modules be present in the function arguments, or else the node panics at startup. We also added a new `SetOrderMigration` function to set the order of running module migrations.
+
+### Improvements
+
+- Speedup improvements (e.g. speedup iterator creation after delete heavy workloads, lower allocations for `Coins.String()`, reduce RAM/CPU usage inside store/cachekv's `Store.Write`) are included in this release.
+- Upgrade Rosetta to v0.7.0 .
+- Support in-place migration ordering.
