High level summary​

One specific Conway feature that received a lot of debate has finally been implemented, namely disallowing stake credentials from withdrawing rewards, that are backed by a key hash and have not delegated to any DRep. This feature will go into effect after the bootstrap phase.

A whole lot more tests were added and few minor bug fixes have been implemented as well. In particular GovInfoEvent ledger event has been fixed, which is unlikely to affect anyone, but it is worth pointing out. Ledger state deserialization bug was fixed that was necessary for the cardano-node-9.1.1 release. Some tech dept was taken care of, like cleanup of unnecessary predicate failures and fixing some flaky tests from Byron and Alonzo eras.

High level summary​

Ledger team continued working on conformance tests and other improvements to the ledger test suite. There was a lot of communication with community members and other core teams about the upcoming hard fork. Some of the Conway specific changes that could affect DApp developer where documented:

There was a minor bug discovered and fixed in how DRep expiration was initialized, which doesn't have any impact on the upcoming Chang hard fork, since DReps cannot affect ratification during the bootstrap phase.

High level summary​

Some minor new features have been added, namely ledger state queries that are necessary for figuring out votes for current proposals and functionality for computing the size of transaction necessary for network communication. Other than that most of the focus still continued to be on improving Conway testing coverage and addition of conformance tests.

Conway​

  • pull-4514 - Add governance related state queries
  • pull-4521 - Added method to compute over-the-wire CBOR encoded transaction size

Testing​

  • pull-4518 - Made conformsToImpl discard generator failures
  • pull-4508 - Make Imp tests setup more realistic
  • pull-4496 - Enable conformance testing for RATIFY
  • pull-4544 - Updated translation of UnRegDRep deposit

Infrastructure and releasing​

  • pull-4531 - Free up disk space in the GHA CI runner before building
  • pull-4526 - cabal.project: Bump index-states and remove allow-newer

High level summary​

Same as with the prior report we are focusing on testing Conway features and conformance testing. One bug was discovered and fixed as a result of this testing, which would only have affected Conway functionality until after the bootstrap phase is over. We also finished fully defining Conway CDDL specification in Haskell.

Conway​

  • pull-4516 - Use motionNoConfidence drep thresholds to ratify NoConfidence
  • pull-4503 - Improvements to plutus debug

Testing​

  • pull-4485 - Improvements for GOVCERT conformance test
  • pull-4495 - Update executable ledger spec
  • pull-4494 - Added minitracing over things with ExecSpecRule instances
  • pull-4440 - Implement more tests in Alonzo.Imp.UtxowSpec.Invalid
  • pull-4493 - constrained-generators: some special-case hooks for the prettyprinter
  • pull-4501 - constrained-generators: Add a callback to saturate constraints
  • pull-4483 - constrained-generators: Start on a tutorial / cheat sheet
  • pull-4437 - Test Conway CDDL using Cuddle
