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:
