March 2026 Monthly Summary (RevenueCat development) Key features delivered: - CI security hardening across RevenueCat mobile repos by pinning GitHub Actions workflow references to immutable commit SHAs, replacing floating version tags to mitigate supply chain risks. Specifics include: - RevenueCat/react-native-purchases: CI Security Enhancement: Pin GitHub Actions to SHA hashes (commit 0f13f9201b991a86c8dce1a6f5f45fcbdc363a5c). - RevenueCat/purchases-android: GitHub Actions workflow security hardening (commit 097ce1be18178c09df66bba34c0fd079c5c9ddaa). - RevenueCat/purchases-flutter: Security hardening: Pin GitHub Actions to immutable SHAs (commit eb3cfc72aa827107287ceaf772d9a0e81ae5b7eb). - Pinning targets various workflow files to SHA references to harden CI while preserving existing logic (e.g., typical workflows across the three repos). - Each repo includes verification steps to confirm CI integrity with pinned SHAs and a test plan to ensure pinned SHAs match expected release tags. Major bugs fixed: - No runtime user-facing bugs were fixed this month. The focus was on security hardening of CI processes to reduce risk exposure and improve CI reliability. The changes are low-risk with no changes to business logic or runtime code. Overall impact and accomplishments: - Strengthened CI security posture across all major RevenueCat mobile repos in one coordinated effort, reducing supply chain risk from GitHub Actions by ensuring reproducible and verifiable CI pipelines. - Improved governance and auditability of CI configurations; standardization across React Native, Android, and Flutter ecosystems. - Maintained existing workflow behavior and build outputs while significantly reducing attack surface for CI pipelines. Technologies/skills demonstrated: - GitHub Actions security best practices, including pinning uses: references to full commit SHAs. - Use of pinning tooling (e.g., pinact) to enforce SHA pinning in workflows. - Cross-repo collaboration and security standardization across multiple mobile platforms (RN, Android, Flutter). - CI integrity verification, risk assessment, and change documentation for governance.

September 2025 monthly summary for RevenueCat/docs focused on OpenAPI spec governance around purchase attribution. Implemented an OpenAPI enhancement to add store_transaction_id to non-subscription objects to improve purchase tracing, followed by a targeted revert for API v1 to maintain stability and backward compatibility.
