Jun 1, 2026June 2026 (UK-Export-Finance/dtfs2) focused on strengthening security, stabilizing release processes, and tightening dependency governance, while delivering targeted feature work and a critical bug fix set. Key outcomes include a CSRF protection refactor using the csrf-sync library with SSO exemptions, followed by a controlled rollback to restore prior behavior after issues, demonstrating robust incident response and test coverage. A fix to role-based login redirection for the payment-report-officer improved post-login UX and accuracy. Release and configuration management activities delivered version 3.1.0 with accompanying tooling updates and governance-aligned adjustments (including a 3.0.1 revert). Dependency hygiene was improved through an axios upgrade to 1.16.0 and tightened Dependabot scheduling to weekly, plus root-level npm update alignment. Overall, the month delivered meaningful business value through stronger security controls, stable release processes, and accelerated patch strategy.
