You seem to be changing native API header files. Please make sure that you:
1. Make compatible changes that don't break existing clients. Usually
this is done by keeping the existing method signatures unchanged.
2. Mark the old stuff as deprecated (see RTC_DEPRECATED macro).
3. Create a timeline and plan for when the deprecated stuff will be
removed. (The amount of time we give users to change their code
should be informed by how much work it is for them. If they just
need to replace one name with another or something equally
simple, 1-2 weeks might be good; if they need to do serious work,
up to 3 months may be called for.)
4. Update/inform existing downstream code owners to stop using the
deprecated stuff. (Send announcements to
discuss-webrtc@googlegroups.com and webrtc-users@google.com.)
5. Remove the deprecated stuff, once the agreed-upon amount of time
has passed.
