Jan 1, 2026January 2026 (Month: 2026-01) highlights: Delivered unified package management for Arize-ai/phoenix by configuring a pnpm workspace across the dashboard and the mock LLM server. This enables a single root pnpm install, removes the standalone pnpm-lock.yaml, and simplifies dependency management. No major bugs were reported this month, and the changes reduce setup time, improve consistency across packages, and lay groundwork for faster cross-package feature delivery. Technologies demonstrated include pnpm workspaces, monorepo configuration, and streamlined dependency orchestration, reflecting a strong focus on developer productivity and long-term maintainability. Impact: enhanced developer experience, easier onboarding, and more predictable builds across the Phoenix project.

Oct 1, 2025Month: 2025-10 — Focused on strengthening authentication and access control for Arize-ai/phoenix. Delivered a feature that enhances User Authentication & Access Control with OIDC/PKCE configuration and introduced a new RBAC 'viewer' role for read-only access. This included new environment variables and guidance for identity providers, options for display names, sign-up control, auto-login, PKCE usage, token endpoint authentication methods, and scope configuration. Documentation was updated to reflect the viewer role and related permissions. The work is supported by commits that update OIDC/PKCE information and add the Viewer Role documentation (GITBOOK-1339).
