No, but the problem with saying "Latest uClibc-ng release" in a commit
log is that it's not going to be very informative 6 months or 2 years
from now, when someone reads the commit log :-)

Saying "Since uClibc-ng 1.0.30, the missing functions are supported"
makes it very clear, and will remain useful in the future.
