August 2025: Delivered foundational MCP infrastructure, enhanced onboarding UX, and CI/CD efficiency improvements, with strong analytics capabilities and model support. Key outcomes include: automation and cost reductions in CI/CD by removing backend tokens and optimizing Playwright tests; MCP protocol scaffolding and server tooling establishing MCP readiness; GPT-5 mini model added to the setup wizard and set as default; session replay enabled in onboarding analytics; WebTrendsQuery introduced for efficient trend analysis on pre-aggregated data. In addition, bug fixes improved reliability: invite links display for self-hosted instances now fallback gracefully when email services are unavailable, and internal proxy routing was corrected by swapping to the proper internal host. These deliverables collectively improve deployment velocity, platform extensibility, onboarding UX, and analytics reliability.
