Feb 1, 2025Month: 2025-02 — Delivered a major Counterparty Core 10.10 release with comprehensive testing, profiling, robustness, and documentation enhancements. Outcomes include a rewritten test harness and expanded integration tests, CI workflow improvements, and Python 3.12/3.13 compatibility alongside CLI/behavior changes (default output for attach/move and --testnet rename). Introduced profiling for catch-up and server execution (--profile) with lifecycle-managed profilers and richer output. Hardened API server robustness by ignoring Bad file descriptor errors during Waitress shutdown. Implemented logging refinements to reduce noise and improve diagnostics via VERBOSE-based stack traces and clearer argument parsing. Updated Release Notes and README for 10.10.x, including API deprecations and test configuration updates.

Jan 1, 2025During January 2025, Counterparty Core delivered a major architectural overhaul (v10.9.0) and subsequent improvements (v10.9.1). The team removed the AddrIndexRs dependency, shifted transaction data sourcing to Bitcoin Core or Electrum, reduced node storage, and enhanced reliability and performance. A rewritten transaction composition module (composer.py) using bitcoin-utils modernized core workflows and supported testnet4. Release notes for v10.9.0 were prepared with documentation fixes, and v10.9.1 included bug fixes, refactoring for testability, and API enhancements, accompanied by upgrade guidance and manual rollback procedures. These changes collectively improve scalability, reduce maintenance costs, accelerate onboarding for developers, and provide clearer upgrade paths for users.
