@liquity/lib-base-v2.0.0 (2021-03-09)

Bug Fixes

• calculate fees at the time of the latest block (d012ad4)
• correct borrowing rate in recovery mode (fb1242a), closes #300
• exclude temporary files from package (2ba1d9b)
• round up when unapplying borrowing fee (097e9ba)

Features

• add maximum acceptable rate param to borrowing and redemption (332f0f6)
• add new property haveUndercollateralizedTroves to LiquityStoreState (6266649)
• allow increasing truncated redemptions to next lowest redeemable amount (f15167d)
• introduce UserTrove class (be15c0f)
• introduce minimum net debt (93e2e77)
• verify the parameters of Trove.create() & Trove.adjust() (cf32217)

BREAKING CHANGES

• getTroves() now returns an array of UserTroves.

It would previously return an array of [string, Trove] tuples, where the
first element of the tuple was the Trove owner's address. After the change,
the owner's address can be found as UserTrove.ownerAddress.

• the change parameter of Trove.apply() is now of type
  TroveChange<Decimal>.

It used to take a TroveChange<Decimalish>, however the only API function
that returns a TroveChange is Trove.whatChanged(), which has a return
type of TroveChange<Decimal>.

Most users therefore won't notice a change.

• Troves can no longer be created without borrowing LUSD.

Any transaction that would result in a Trove with less debt than the new
constant LUSD_MINIMUM_DEBT will be reverted.

• fees has been moved from LiquityStoreBaseState
  to LiquityStoreDerivedState.

Most users won't need to make a code change. However, care should
be taken to upgrade both SDK packages at the same time, to ensure
compatibility.
