+## [v3.0.5] - 2025-10-14
+
+### Added
+- **HTTP/2 Origin Support:** Added support for enabling HTTP/2 protocol between `cloudflared` and origin services via the new `dockflare.http2_origin` label and UI controls. Required for gRPC services. Only applies to HTTP/HTTPS services.
+- **Disable Chunked Encoding Support:** Added support for disabling chunked transfer encoding over HTTP/1.1 via the new `dockflare.disable_chunked_encoding` label and UI controls. Useful for WSGI servers (Flask, Django, FastAPI) and other origins that don't properly support chunked requests. Only applies to HTTP/HTTPS services.

 > **Tip:** Starting with DockFlare v3.0, you can skip `dockflare.zonename` for most workloads. The master detects the correct Cloudflare zone by matching the hostname suffix and only falls back to the configured default zone when it cannot find a match. Provide the label when you intentionally want to place a record in a different zone.
