March 2026: Implemented an automated Dependabot PR labeling and merging workflow in starcoin, significantly reducing manual review and speeding up dependency updates. The feature operates via GitHub Actions to auto-label Dependabot PRs, preserve labels for cargo updates, and auto-merge after successful CI (commit 36d61f5d27f267477db30525b75a420785f7d97c). This change improves CI/CD efficiency, ensures consistent PR categorization, and accelerates release cadence.
