v18.0.0

Gaia v18.0.0 Release Notes DEPRECATED

⚠️ This release is deprecated and should not be used in production. Please use v18.1.0 instead.

📝 Changelog

Check out the changelog for a list of relevant changes or compare all changes from last release.

Refer to the upgrading guide when migrating from v17.2.x to v18.x.

🚀 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

When the PSS enabled chain binary lands on mainnet, new consumer chains will be able to:

• choose the % of Cosmos Hub's voting power that is required to operate the consumer chain
• use allow/denylists to customize validator participation
• choose a per-validator voting power maximum (voting power cap)
• use a different number of validators compared to the Cosmos Hub (validator number cap)
• choose to run as an "Opt-in" chain (running the chain is not mandatory for validators)
• have validators choose a different commission rate on their chain
