||||
There are times when we make changes that include a temporary shim for |
||||
backward-compatibility (e.g., a macro or some other function to preserve |
||||
the original API) to avoid having to bump the major version number in |
||||
the next release. However, when we do eventually want to release a |
||||
feature that does change the API in a non-backward-compatible way, we |
||||
will wind up bumping the major version number anyway, at which point we |
||||
can take the opportunity to clean up any pending backward-compatibility |
||||
shims. |
||||
|
||||
This file lists all pending backward-compatibility changes that should |
||||
be cleaned up the next time we are going to bump the major version |
||||
number: |
||||
|
||||
- remove `ClientContext::set_fail_fast()` method from |
||||
`include/grpc++/impl/codegen/client_context.h` (commit `9477724`) |

#Overview |
||||
|
||||
This directory contains source code for gRPC protocol buffer compiler (*protoc*) plugins. Along with `protoc`, |
||||
these plugins are used to generate gRPC client and server stubs from `.proto` files. |
