• Feature: Single Sign-On via OpenID Connect (OIDC) alongside magic-code login — off by default and enabled per deployment with OIDC_* env vars, the setup wizard, or Settings → SSO (client secret encrypted at rest), so the sign-in page shows an SSO button only when it is turned on. Invited-users-only by default with opt-in just-in-time provisioning gated by a verified-email domain allowlist; identities are keyed on the durable issuer+subject pair (never email alone) and login still requires a workspace invite or ROOT_EMAIL for access. Uses Authorization Code + PKCE and works with any compliant provider (Google Workspace, Keycloak, Okta, …); adds the federated_identities system table (migration v34).
• Fix: One-click unsubscribe (RFC 8058) now works end-to-end. The /unsubscribe-oneclick endpoint takes its parameters from the List-Unsubscribe URL query string — it previously tried to JSON-decode the POST body and rejected every mail-client request with 400 "Invalid request body". The emitted URL now also carries the email_hmac the endpoint verifies. And the endpoint no longer applies User-Agent bot detection, which silently dropped the automated POSTs that Gmail/Yahoo/Apple (and tools like curl) actually send (returning 200 while leaving the contact subscribed); it instead requires the RFC 8058 List-Unsubscribe=One-Click body token to deflect bare prefetch/scanner POSTs (#362).
• Feature: Google Gemini is now a selectable LLM provider for the AI agent (blog & email generation), alongside Anthropic and OpenAI — configure it under Settings → Integrations with a Gemini API key and model (default Gemini 3.1 Pro); when multiple LLM integrations are configured, a provider dropdown in the AI chat selects which to use.
• Feature: Search broadcasts by name and filter by status on the broadcasts list — a grouped status filter (All/Draft/Scheduled/Sending/Sent/Failed) plus a debounced name search beside it, both persisted in the URL; the broadcasts.list API now accepts multiple statuses and a name search (#335).
