August 2025: Delivered key feature in bsv-blockchain/go-wallet-toolbox that enhances BRC29 address generation for self vs counterparty. Implemented new functions in the brc29 package to generate recipient addresses from sender side or self, clarified key management, and updated examples and tests. This reduces misaddressing risks in cross-party transactions and strengthens the wallet's address handling surface. No major bugs fixed this month; stability is maintained through testing. This work lays groundwork for future multi-party/addressing features and improves developer onboarding.

February 2025 focused on delivering robust SPV wallet capabilities, improving reliability, and expanding test coverage. Key features include UTXO-based input selection for transaction outlines with BEEF/RAW hex support and broad test coverage. Reliability improvements stabilized startup initialization by ensuring dependencies load in the correct order. Correctness improvements fixed default nSequence handling on inputs, reducing edge-case failures in transaction finality and timelock handling. Database reliability was enhanced with PostgreSQL-specific fixes for BeefHex/RawHex handling and SpendingTX trimming via a GORM hook. A deduplication fix for input TX IDs in BEEF transfers was implemented to prevent double-spend risk, accompanied by tests. Additionally, API documentation versioning/licensing updates and testing infrastructure enhancements supported ongoing release readiness and testability.
