Strawberry GraphQL @ 0.327.2

Released September 3, 2026 at 6:43 AM GMT+00:00

This release fixes the legacy graphql-ws protocol handler so that subscriptions which complete on their own (or fail before execution) release their slot on the connection.

Previously, completed operations were kept in the handler’s bookkeeping until the client sent a stop message for them, reused their operation id, or disconnected. On connections with max_subscriptions_per_connection configured, a client using distinct operation ids could therefore hit Subscription limit reached even though none of its earlier subscriptions were still active. The graphql-transport-ws handler was not affected.

Sending a stop message for an operation that has already completed is now a no-op instead of an error.
