Changelog

1.0.0

(This release is the one from the canonical lauch onstage in Bogota. We were missing semantic versioning at the time, but we call this the 1.0.0 release retroactively.)

Deploy commit eda322894a5ed379bbda2b399c9d1cc65aa8c132

1.1.0

  • Introduce semantic versioning to the Deployer and RToken
  • RTokenCreated event: added version argument
event RTokenCreated(
        IMain indexed main,
        IRToken indexed rToken,
        IStRSR stRSR,
        address indexed owner
    );

=>

event RTokenCreated(
        IMain indexed main,
        IRToken indexed rToken,
        IStRSR stRSR,
        address indexed owner,
        string version
    );
  • Add version() getter on Deployer, Main, and all Components, via mix-in. To be updated with each subsequent release.

Deploy commit d757d3a5a6097ae42c71fc03a7c787ec001d2efc

1.2.0

Candidate release for the "all clear" milestone

  • Support multiple beneficiaries via the FacadeWrite
  • Add RToken.issue(address recipient, uint256 amount) (like RToken.issue(uint256 amount)) to support issuance from another smart contract
  • Add FacadeRead.primeBasket() + FacadeRead.backupConfig()
  • Switch from price point estimates to price ranges; all prices now have a low and high. Impacted interface functions:
    • IAsset.price()
    • IBasketHandler.price()
  • Replace IAsset.fallbackPrice() with IAsset.lotPrice(). The lot price is the current price when available, and a fallback price otherwise.
  • Introduce decaying fallback prices. Over a finite period of time the fallback price goes to zero, linearly.
  • Remove IAsset.pricePerTarget() from interface
  • Selectively sweep rewards from RToken
  • Add safeMulDivCeil() to ITrading traders. Use when overflow is possible from 2 locations:
  • Introduce config struct to encapsulate Collateral constructor params more neatly
  • In general it should be easier to write Collateral plugins. Implementors should only ever have to override 4 functions: tryPrice(), refPerTok(), targetPerRef(), and claimRewards().
  • Add .div(1 - maxTradeSlippage) to calculation of shortfallSlippage in RecollateralizationLib.sol:L188.
  • Bugfix: Do not handout RSR rewards when no one is staked
  • Bugfix: Support small redemptions even when the RToken supply is massive
  • Bump component-wide version() getter to 1.2.0
