[llvm-dev] [cfe-dev] Mailing list changes this week

Hi,

Is this monotonic incrementing identifier part of the email? I think
it would really complicate buildbot maintenance if we didn't have it
in obvious places. For instance, we have a (hacky) monitoring page for
our ARM/AArch64 buildbots [1] and it really helps a lot to just look
at the commit range for the last build to know if a fix actually
worked or not ("is the fix commit in that range? if not wait a bit
more before investigating"). Using just a git hash and having to
manually count commits would be a waste of time.

Just my 2c,
Diana
