Cosmos SDK v0.45.0 Release Candidate 1

Release Notes

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.

State-Breaking Changes

There are few important changes in gas consumption, which improve the gas economics:

• 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.
