You'll notice
Telemetry endpoint settings now accept gRPC-style URL schemes like grpc, otlp and tcp, not just http/https
What
When Claude Code checks the OTLP (OpenTelemetry Protocol, a standard format for exporting telemetry data) endpoint environment variables ANT_OTEL_EXPORTER_OTLP_ENDPOINT and OTEL_EXPORTER_OTLP_*_ENDPOINT, it now accepts a wider range of URL schemes: grpc, grpcs, otlp, xds, tcp, udp, tls, h2, h2c, and http2, in addition to the previously accepted http and https.
Why
This avoids Claude Code incorrectly flagging a valid gRPC-based or other non-HTTP telemetry endpoint URL as misconfigured, which matters if your telemetry collector is set up to receive data over one of these protocols instead of plain HTTP.
