The Cosmos community is voting on the "Gaia v16 upgrade" proposal, and the voting ends on May 10.
According to reports, the Gaia v16 upgrade will include 4 major new features: ICA controller submodule, IBC rate limit module (with the initial rate limit outlined in Proposal 890), IBC fee module, ICS epochs (part of ICS v4.1.0). At the same time, after the governance vote is approved, the relevant binaries of Gaia v16.0.0 need to be updated and submitted to the Cosmos Hub. The update process takes about two weeks.
