🚀 Highlights

This release adds the following features:

• Permissioned CosmWasm (as per prop 895 ) enables the governance-gated deployment of CosmWasm contracts. See this forum discussion for more details on what contracts should be deployed on the Hub.

• Skip's feemarket module (as per prop 842 ) enables the dynamic adjustment of the base transaction fee based on the block utilization (the more transactions in a block, the higher the base fee). This module replaces the x/globalfee module .

• Expedited proposals (as per prop 926 ) enable governance proposals with a shorter voting period (i.e., one week instead of two), but with a higher tally threshold (i.e., 66.7% of Yes votes for the proposal to pass) and a higher minimum deposit (i.e., 500 ATOMs instead of the 250 for regular proposals). Initially, only `MsgSoftwareUpgrade` and `MsgCancelUpgrade` can be expedited.

The release also bumps the following dependencies:

• Golang to v1.22

• Cosmos SDK to v0.47.16-ics-lsm

• IBC to v7.6.0

• ICS to v4.3.0-lsm
