[Unreleased]

[1.0.0] - 2019-10-21

Added

prml/attestation/*

• Added attestation runtime module

prml/doughnut/*

• Add PlugDoughnut wrapper struct to allow doughnut integration with SignedExtension hooks
• Add PlugDoughnutDispatcher as the defacto Plug implementor for DelegatedDispatchVerifier

node/runtime/src/lib.rs

• Add doughnut proof as an optional first parameter to the node/runtime SignedExtra payload allowing doughnut's to be added to extrinsics

• Add DelegatedDispatchVerifier and Doughnut proof type to system::Trait type bounds

core/sr-primitives/src/traits.rs

• Blanket impl SignedExtension for Option<T> to allow Optional in extrinsics
• Add MaybeDoughnut trait for SignedExtension type to allow extracting doughnut from SignedExtra tuple
• impl MaybeDoughnut for SignedExtension macro tuple of all lengths

Changed

core/sr-primitives/src/traits.rs

• Make trait SignedExtension::pre_dispatch method receive self by reference (&self), instead of move (self)

srml/staking/*

• Add RewardCurrency type to allow paying out staking rewards in a different currency to the staked currency
• Change fn make_payout() so that RewardCurrency is paid to the stash account and not added to the total stake, if the reward currency is not the staked currency

srml/system/src/lib.rs and srml/support/src/origin.rs

• Add DelegatedOrigin variant to RawOrigin for delegated transactions
• Add MaybeDoughnutRef trait for extracting doughnut proof from origin without move in runtime module methods

srml/support/src/dispatch.rs

• Add DelegatedDispatchVerifier check to decl_module! expansion. This allows doughnut proofs to be checked when an extrinsic is dispatched using the <T as system::Trait>::DelegatedDispatchVerifier impl
