[2.3.0] 04.06.2026

Added

• PAH: staking switched to non-minting; emission via pallet-dap drips (#1159)
• PAH: DapStagingAccount is the sink for fees, slashes and RewardRemainder (#1159)
• KAH: pallet_recovery modernized (#1159)
• PAH & KAH: add asset-conversion and vesting precompiles (#1159)
• PAH & KAH: pallet_revive::EthExtra supports multi-version Ethereum extensions (#1159)
• Bridge Hub Polkadot: expose Snowbridge InboundQueueV2Api::is_message_relayed runtime API (#1159)
• PAH & KAH: add PrevalidateAttests transaction extension to the TxExtension (#1156)

Changed

• Enable multiple blocks per slot for all remaining system parachains (BridgeHub Polkadot/Kusama, Coretime Polkadot/Kusama, Collectives Polkadot) (#1154)
• Update all runtimes to polkadot-sdk unstable2604 (#1159)
• PAH & KAH: K↔P bridge router exports unpaid (UnpaidExport = true) (#1159)
• PAH & KAH: enable pallet_revive auto mapping feature (#1159)
• PAH & KAH: ERC-20 assets precompile permit() renamed to use_permit() (#1159)
• PAH: redirect XCM trader fees (native and swap) to DapStagingAccount instead of StakingPot (#1159)
• PAH: filter staking.reap_stash from both BaseCallFilter and the XCM SafeCallFilter while the validator self-stake transition to higher bond. See Ref: #1890 (#1159)
• Collectives Polkadot: Increase the Secretary Collective salary budget (#1172)
• Align all runtimes to use the same values for e.g. TransactionByteFee and some other clean ups. (#1175)
• PAH & KAH: switch pallet_multi_asset_bounties source types to the upstream BountySourceFromPalletId / ChildBountySourceFromPalletId and migrate bounty/child-bounty pot funds to the new [u8; 3]-prefix account derivation (#1168)
• Asset Hub Polkadot & Kusama, People Polkadot & Kusama: switch to 24s Aura slot duration. Longer Aura slots improve elastic scaling throughput and censorship resistance, while keeping the parachain block time unchanged. (#1174)
• Flexible minimum validator set size on rc (#PR1193)
• Configurable salary parameters for Fellowship and Secretary (#1186)
