According to Odaily Planet Daily, Cosmos Hub announced on the X platform that Proposal 914 has been approved by the community and will implement the v16 software upgrade. Cosmos Hub said that it will implement this upgrade at block 20440500 (expected to be on May 15). It is reported that the v16 upgrade includes new key features implemented by upgrading to SDK v0.47: IBC rate limit module, which prevents a large inflow or outflow of IBC tokens in a short period of time, adding an extra layer of protection for IBC transfers; ICA controller submodule, which enables Hub users to use their Hub accounts to perform operations on other chains; IBC fee middleware, which creates IBC channels through in-protocol relay incentives.
