May 26, 2023: grand-1 testnet upgrade from v0.5.0 or v0.5.1. We are making the versioning between testnet and mainnet consistent.

Noble Radon Upgrade

This upgrade introduces additional noble fee mechanics

Global min-fee module

A minimum fee is now held in the chain state. If a validator or full-node configures a minimum-gas-prices in app.toml below the minimum-fee in the chain state, the minimum fee from state will be used instead.

Tariff module

An additional fee can be collected for outgoing IBC transfers of a specific denom. This is a basis points (BPS) fee taken proportionally to the transfer amount, up to a maximum amount.
Fee distribution is also modified to distribute a share of fees to a configurable list of entities before the distribution-module validator distribution.
