Cosmos SDK v0.45.2 Release Notes

This release introduces bug fixes and improvements on the Cosmos SDK v0.45 series:

Highlights:

Add hooks to allow modules to add things to state-sync. Please see PR #10961 for more information.
Register EIP191 as an available SignMode for chains to use. Please note that in v0.45.2, the Cosmos SDK does not support EIP-191 out of the box. But if your chain wants to integrate EIP-191, it's possible to do so by passing a TxConfig with your own sign mode handler which implements EIP-191, using the new provided authtx.NewTxConfigWithHandler function.
Add a new rollback CLI command to perform a state rollback by one block. Read more in PR #11179.
Some new queries were added:
- x/authz: GrantsByGrantee to query grants by grantee,
- x/bank: SpendableBalances to query an account's total (paginated) spendable balances,
- TxService: GetBlockWithTxs to fetch a block along with all its transactions, decoded.
Some bug fixes, such as:
- Update the prune everything strategy to store the last two heights.
- Fix data race in store trace component.
- Fix cgo secp signature verification and update libscep256k1 library.

See the Cosmos SDK v0.45.2 Changelog for the exhaustive list of all changes and check other fixes in the 0.45.x release series.
