In April 2025, delivered mission-critical reliability improvements and customer-facing workflow enhancements across the Konflux CI suite. Implemented a curl-with-retry Bash utility to transparently handle Jira API rate limiting, deployed across release-service-utils and release-service-catalog. Hardened Jira rate-limit handling with improved debugging (set -x) and a version bump to 0.2.1. Strengthened embargo-check CVE handling, stabilizing CVE ID checks, mitigating race conditions with temporary files, and ensuring CVEs are present in release notes. Fixed formatting issues in file updates processing and made the SBOM upload more resilient to intermittent S3 errors. Updated advisory_url routing to point to the customer portal, extended advisory task timeout to 45 minutes, and aligned E2E tests with customer workflow by routing to the customer portal and switching the default branch to development.
