v0.2.0

Breaking Framework Changes

• Test suite to test against private network has undergone following changes:
  • Type to represent context's user now doesn't have collateral (in PR #108), see it's fields here.
  • Context now has one funder and 8 other users, these other users (ctxUser2 to ctxUser9) start with the same amount of funds and funder (ctxUserF) in contrast starts with a lot more ada (done in PR #96). See more details about exact funds in our guide for it, here.
  • Redundant type UserIdx is removed (in PR #87), changing the interface of functions in Ctx.hs, again refer to our guide to see use of latest interface.
  • Function assertUserFunds has been changed to check against exact transaction fees rather than in window in PR #100.
• Framework now has support for multi-asset collateral (PR #97 & PR #108), removing the need for dapps to require a UTxO for collateral as framework is capable for selecting suitable UTxO for it. For more details, see these two pages of our guide, Creating Endpoints & Browser Integration. This has led to interface of functions in Node.hs to change where instead of requiring reference to collateral UTxO, it's now a tuple inside Maybe value where Nothing represents that framework is to choose for collateral (if required) and in Just case we get a tuple of reference to collateral with a boolean, if this boolean is False, given collateral is taken as collateral to build transaction and framework doesn't spend it (unless explicitly mentioned by transaction skeleton) and if the boolean is True, framework checks if the given collateral UTxO has exactly 5 ada or not, if yes, behavior is like False case and if no, behavior is as Nothing case, i.e., framework picks suitable UTxO to use as collateral and is also free to spend it.
• someUTxO now takes parameter to denote for script language (changed for in PR #114) and only returns UTxO which is translatable to that language, i.e., usable by script of that language.
  • In particular, there is additions to GYTxMonad, namely, ownAddresses & availableUTxOs (in PR #124) which would help in writing custom version of someUTxO if required, such as one done in someUTxOWithoutRefScript.

Other Framework Features

• Earlier, when performing browser integration, there was need to use a library such as CML to add for witness (obtained from wallet api's signTx method) to our transaction body, which just misses this key witness. Besides complication involved in using & understanding another library, this led to issues where transaction hash was getting modified due to different representation of CBOR for involved structures in such libraries. Adding for this is now possible to be done entirely using Atlas (done in PR #99), as illustrated in Creating Endpoints & Browser Integration section of guide.
