Where can I find the protobuf files for the Ledger API and DAML-LF for a given release? I need to download them automatically as part of a CI pipeline. ---

Ah, I just found them myself, they’re provided as artefacts for each release: [https://github.com/digital-asset/daml/releases/download/v1.0.0/protobufs-1.0.0.zip](https://github.com/digital-asset/daml/releases/download/v1.0.0/protobufs-1.0.0.zip) ---

I noticed in that zip that `ledger` and `daml_lf_dev` files are under the `daml` namespace, but `daml_lf_1_6`, `daml_lf_1_7` and `daml_lf_1_8` are under the `digitalasset` namespace. Shouldn’t they all be in the same? ---

No, as part of 1.0.0 we transitioned everything we could to `com.daml`, but doing the same for existing DAML-LF protobuf packages could break existing code. ---

Makes sense, thanks. The dependency `google/rpc/status.proto` is not included in the zip. Would it make sense to do so? Otherwise I don’t know where or which version of this file I need to pull in. ---

The argument is fair, but rather then including I think it would make sense to document the correct source. That would be here: [https://raw.githubusercontent.com/grpc/grpc/master/src/proto/grpc/status/status.proto](https://raw.githubusercontent.com/grpc/grpc/master/src/proto/grpc/status/status.proto) The version is not particularly relevant as this definition never changed, but if you want to hook up to a stable version to protect yourself against future changes you can use the latest one: [https://raw.githubusercontent.com/grpc/grpc/v1.28.1/src/proto/grpc/status/status.proto](https://raw.githubusercontent.com/grpc/grpc/v1.28.1/src/proto/grpc/status/status.proto) ---
