Oraichain Mainnet Release Notes

This release focuses on fixing the IBC transfer int overflow error when the transfer amount is too large (over 2^63).

We forked the Cosmos SDK repository to fix the bug even though it was addressed and fixed in a newer version of IBC. The reason is that we are running multiple CosmWasm contracts in production with CosmWasm version 0.13.2. If we upgraded Cosmos SDK to v0.45.1, then we would need to upgrade CosmWasm as well, which would halt all services.
