Release arize-phoenix-client: v3.4.0 · Arize-ai/phoenix

3.4.0 (2026-09-03)

server: GET /v1/model_providers no longer returns custom providers or a next_cursor, and built-in entries expose provider rather than kind + provider_key. Custom providers move to GET /v1/custom_model_providers. The endpoint is unreleased, so no published client is affected.
