Hi devs/contributors,
The next time you checkout HEAD and open a .proto file, you may notice this
line at the top of the file (after the Apache license, of course):
syntax = "proto2";
This has been added to all our protobufs in order to allow different
versions of the protobuf compiler to process our protobufs. This change *does
not *change anything about the generated code, or the wire format, or
anything else. The new line purely addresses a warning printed by protoc.
If you need to add any new protobufs, make sure you add the "syntax = ..."
in future.
See this and related issues for some more details:
