v1 Release Candidate 1

First shot at deploying v1, to be either replaced by a v1-rc2 (if important bugs/necessary changes are found), or blessed as "official v1" if it still seems mainnet-worthy after significant use.

v0.50

The last version which includes both the (old) Uniswap v2 oracle, and the (new) Uniswap v3 oracle, before we remove now-unused code: Uniswap v2 oracle, Compound OpenOracle, and the Oracle.refreshPrice() function they necessitated.

ABDK Audit Response #1

Incorporates many suggestions by/responses to ABDK's security audit with its 115 (!) comments.

ABDK Audit

This is the moderately cleaned-up version of the code submitted to ABDK for USM security audit#⁠2.

Stored minFumBuyPrice

Last tested version which stores minFumBuyPrice, decreasing it over time. Releases after this use the new, continuous-rather-than-discontinuous math, where the minimum FUM buy price is inferred, and only timeSystemWentUnderwater (the time at which minFumBuyPrice starts decreasing) is stored.

Static Oracle Price

Last tested version before we deploy the new "moving mid" feature (#79), which also changes fees to be based on % change in ETH pool rather than % change in debt ratio. This v0.1.2 release still has a fixed mid based on the latest oracle price, and debt-ratio-based fees.

Solidified Audit

This is the latest reasonably-stable version using the TWAP Uniswap oracle rather than Uniswap spot prices. We also stripped out a bunch of currently unused contracts (eg the Maker oracle and Uniswap spot pricing) to make for a trimmer codebase.

Spot Oracles

Last tested version before we switch from Uniswap spot prices to Uniswap TWAP.
