Apr 1, 2026

April 2026 (TryGhost/Ghost) delivered a disciplined migration of the welcome email workflow to a new automation data model, introduced dormant tables and runs for the Welcome Email Automations feature, and prepared the platform for broader automation capabilities with guarded UI scaffolding and feature flags. Key outcomes include: a data-model overhaul migrating from automated_emails to welcome_email_automations and welcome_email_automated_emails, plus creation of a dormant automation_runs table; migration work to shift welcome emails to automation runs powered by Rails; a private, dormant drip sequences feature flag and hidden admin UI scaffold; a defined endpoint for listing automations and new automation permissions; scheduler integration to drive automation polls; and explicit imports for models to improve startup performance and maintainability. Across the codebase, automation-related releases advanced with improvements in type safety, test reliability, and CI/security, while cleanup (removing unused endpoints, flag removals, and UI cleanup) reduced surface area. Overall, this work improves reliability, scalability, and speed of automation features, delivering measurable business value by enabling more robust onboarding automation, safer feature rollout, and clearer developer interfaces.

January 2026 performance and delivery highlights: a focused period of feature delivery, reliability improvements, and codebase modernization across Ghost and the framework. Key work spans sniper links infrastructure and integrations, portal enhancements and TypeScript/test migrations, and substantial test-suite/CI stabilization. Deliveries emphasized business value through improved onboarding, security posture, and developer velocity while reducing CI flakiness and maintenance overhead. Key outcomes include: - Sniper links: introduced core infrastructure (feature flag, getSniperLinks, MX lookup) and expanded provider support, enabling more accurate, provider-aware sniper links. - Sniper integration in user flows: updated magic links endpoint to return sniper links; added sniper link generation in sign-up and integrated sniper link button in the OTC flow. - Portal improvements: DRYed signin return in Portal; converted portal tests to TypeScript; code quality and cleanup initiatives to reduce debt and improve maintainability. - Email handling improvements: robust email normalization and parsing, with a move to dedicated parse-email-address functionality and CI/test correctness improvements. - Test suite reliability and CI: migration from Should.js to Node assert/Sinon across multiple tests, stabilization of CI performance tests, and targeted fixes for flaky tests (EventStorage, UrlTranslator, AdapterManager, redirects, Mailgun tests). - Codebase cleanups: removal of deprecated parse-email-address package in framework and related cross-repo cleanups; portal labs flag removals as part of flag remapping. Business value realized: improved onboarding quality and reliability, faster and more predictable CI pipelines, reduced maintenance burden, and clearer, more scalable paths for future features (e.g., sniper links and portal enhancements).
