Chore

• update remaining references to gitlab
• update readme to point to github

Feat

• vault liquidation from off-chain worker
• extract p2wsh addresses
• dispatchable amounts should be compact
• emit event when issue amount changes
• vault nomination

Fix

• remove nomination liquidation
• correct txid calculation when there is witness data
• RedeemRequest serialization
• broken unit tests
• Merge errors
• average issue size calculation
• don't check parachain status in internal vault_reg functions
• only increment active_block_count when status is running
• check parachain status in on_initialize
• use status_not_shutdown through the project
• calculate tx_id rather than using user input
• make replaceRequest storage non-optional
• don't allow issues while btc-relay is initializing
• vault auto liquidation weight + small optimization + missing benchmark
• benchmarking
• reject transactions with duplicate recipients
• Nomination merge errors
• filter banned vaults in get_vaults_below_premium_collateralization
• don't allow vault to accept/auction replace themselves
• merge vault v3 into v2

Refactor

• inline initiate_replace
• convert btc-relay pallet to FRAME v2
• convert vault-registry pallet to FRAME v2
• use checked math for increase / decrease total locked
• use consts for name, symbol and decimal in currency
• simplify nomination conversions
• set decimals at genesis, use on exchange-rate calculation
• rename other helper methods
• calculate expected redeem size based on input&outputs
• rename DOT and PolkaBTC to Backing and Issuing
• merge collateral and treasury wrappers into currency pallet
• convert collateral pallet to FRAME v2
• convert treasury pallet to FRAME v2
• derive sovereign account for modules
• convert security pallet to FRAME v2
• Use slash_collateral instead of repatriate_reserved
• more consistently use Pallet instead of Module
• move checks into dispatchable functions
• rename Module -> Pallet
• rename weights->default_weights
• use active_block_number everywhere
• don't use newtype for ActiveBlockNumber

Test

• txid with and without witness
• redeem underpayment
• oracle when parachain is shutdown
• increment_active_block
• check that oracle usage fails when oracle is offline
• parachain shutdown check
• forged raw_tx
• withdraw and add collateral
• issue/redeem/replace expiry

Wip

• Begin work on fee distribution
