Polkadot v0.9.0

on GitHub

Upgrade priority: ❗ HIGH ❗ Please upgrade your node as soon as possible

• Kusama node operators: This release introduces client changes that are required for the correct operation of parachains. In order for your node to continue syncing after the next runtime upgrade, please upgrade your node as soon as possible.
• Polkadot node operators: This release introduces a new host function. In order for your node to continue syncing after the next runtime upgrade, please upgrade your node as soon as possible.

Notes for Validators:

• In order to support parachains, private or rotating IP addresses will not work, you must have a public static IP address for your validator
• The flag --no-private-ipv4 would disable the node from searching for private IP addresses (like you might on a local / dev chain). This flag's behaviour is now the default
• A validator node must have inbound p2p ports open. Your node will not be able to participate in validating parachains if it does not have this.

Native runtimes (with release v0.9.0, runtime version numbers have been unified):

• Polkadot: 9000
• Kusama: 9000
• Westend: 9000

This release was tested against the following versions of rustc. Other versions may work.

• rustc 1.51.0 (2fd73fabe 2021-03-23)
• rustc 1.53.0-nightly (7f4afdf02 2021-04-22)

WASM runtimes built with srtool using rustc 1.52.0-nightly (d6eaea1c8 2021-03-14).
