v0.168.0 - Conway PV9 gating and CBOR diagnostic navigation

  • Date: 2026-05-09
  • Version: 0.168.0

Summary

This release adds Conway PV9 governance checks that reject governance actions and parameter updates that must wait until Plomin or PV10, adds CBOR inspection tools that can jump to a byte position and show an annotated hex view, fixes blockfetch cleanup during disconnect and shutdown scenarios so later requests do not stall, and expands ledger regression coverage for forward compatible handling when future cost model lists grow.

New Features

  • Added Conway governance checks that reject governance actions and restricted parameter changes that are not allowed until Plomin or PV10, improving protocol version correctness and producing clearer validation failures.
  • Expanded CBOR diagnostics so callers can find nodes and paths by byte offset, review annotated hex views, and decode one or more items into diagnostic trees for easier binary inspection and troubleshooting.

Bug Fixes

  • Fixed blockfetch request cleanup so disconnects, shutdowns, and error paths release correctly and later GetBlock and GetBlockRange calls do not hang behind an orphaned busy lock.

Additional Changes

  • Expanded ledger and compatibility coverage for longer cost model lists so forward compatible Conway and Plutus handling is validated across encoding, parameter updates, and genesis loading.

v0.167.0 - diagnostic parsing and DMQ node-to-client support

  • Date: 2026-05-05
  • Version: 0.167.0

Summary

This release adds a new CBOR diagnostic parser and CIP-0137 DMQ node-to-client support, hardens rational value serialization and protocol startup cleanup, aligns Conway and Plomin protocol version handling, and includes routine dependency, documentation, and lint maintenance.

New Features

  • Added a CBOR diagnostic parser that can show offsets, preserve formatting detail, and make complex encoded data easier to inspect and troubleshoot.
  • Expanded CIP-0137 DMQ node-to-client support so applications can submit and receive distributed messages through dedicated local message protocols.

Bug Fixes

  • Fixed rational value JSON serialization so large and negative values encode reliably and zero denominator inputs fail cleanly instead of triggering panics.
  • Improved protocol startup cleanup so failed handshake and transaction submission send attempts stop cleanly and avoid lingering shutdown errors.
  • Corrected Conway and Plomin protocol version handling so version names and upper bounds stay aligned with current era support.
