Changelog for the runtimes governed by the Polkadot Fellowship.

The format is based on Keep a Changelog.

[1.9.0] 26.09.2025

Added

• Enable the Asset Hub Migration for Kusama at block 30423691, projected to be Tuesday 7th Oct 8 AM UTC (polkadot-fellows/runtimes/pull/935)
• Code for the Asset Hub Migration (polkadot-fellows/runtimes/pull/856)

Changed

• Pallet XCM - Disable reserve_asset_transfer for DOT|KSM (polkadot-fellows/runtimes/pull/880)
  🚨 Pallet XCM's limited_reserve_transfer_assets and reserve_transfer_assets extrinsics now returns an error when it determines that a reserve transfer of DOT|KSM has to be done.
  This is a safeguard in preparation for the Asset Hub Migration (AHM), where the reserve of DOT|KSM will change from the Relay Chain to Asset Hub.
  After the migration, another patch will remove this error case and use the correct reserve.
  🚨 For DOT|KSM cross-chain transfers please use transfer_assets_using_type_and_then or execute.
  Please see this Polkadot forum post for more details.
