Jul 1, 2025July 2025 (ssvlabs/ssv) – Key features delivered: - CI/CD Workflow Deduplication: Modified GitHub Actions triggers to run CI only for pull_request opened/synchronize events, reducing duplicate CI runs and improving PR feedback times. (commit 594c3a0de013543d25613f08b274f0ac54a22eb8, #2362) - TLS Certificate Verification Robustness: Multi-Source Hostname Resolution: Enhanced TLS hostname verification by loading hostname from multiple certificate data sources and added tests for hostname extraction and fingerprint matching to cover scenarios when the primary hostname field is missing. (commit 5d1897515314595eee4a0aa5709f494152308c38, #2383) Major bugs fixed: - fix(ssvsigner) tls load hostname from all cert data (#2383): Resolved hostname loading gaps by aggregating from all certificate data sources and added tests. Overall impact and accomplishments: - Reduced CI churn and accelerated PR validation, delivering faster feedback to developers and lowering CI compute costs. - Strengthened security and reliability of TLS hostname verification with broader data-source coverage and test coverage, reducing risk of hostname resolution failures in production. Technologies/skills demonstrated: - GitHub Actions workflow optimization, CI/CD efficiency, test-driven development; TLS certificate handling, multi-source hostname resolution, and security-focused testing.
