Item	Value
Priority	High

Reference	Docker configs

Network	Required Versions
Mainnet	`geth v0.3.1`, `goat v0.2.4`
Testnet3	`geth v0.1.8`, `goat v0.2.4`

If your current Geth version is not v0.3.0 on mainnet or v0.1.7 on Testnet3, upgrade to that prerequisite version before applying this release.

v0.3.0

Item	Value
Priority	Medium
Scope	GOAT Geth only
Mainnet geth	`v0.3.0`
Testnet geth	`v0.1.7`
Reference	Docker configs

This upgrade adjusts the gas price oracle strategy and changes the minimum priority fee to 0.00013 gwei.

Wallets, dapps, and service providers should use eth_maxPriorityFeePerGas to get the priority fee.
RPC node and validator maintainers should plan for a database migration. After upgrade, downgrading to a lower version is not supported.
During migration, CPU and disk I/O may be higher than normal. See the data migration release notes.

Recommended upgrade order:

Upgrade all RPC nodes.
Wait for confirmation from the GOAT Network team.
Upgrade all validators.
