Episode notes
Structured Six‑Month Release Cycle
- Bitcoin Core releases are produced roughly every six months with a feature freeze followed by release-candidate testing.
- Multiple release candidates and heavy testing ensure stability before a final major release.
Review Is The Real Bottleneck
- Bitcoin Core maintainers review and merge contributions after multi-person vetting and testing.
- Review burden often outweighs code writing, requiring many review cycles per pull request.
Migrate Legacy Wallets Now
- Migrate legacy Berkeley DB wallets to descriptor wallets using provided tools before v30 removes legacy creation.
- Keep backups and use migrate-wallet RPC to preserve access to old funds.
