No. libnghttp2 added one symbol, and (correctly, i.e. following the usual
practice), it changed the suffix from .so.14.23.0 to .so.14.24.1.  (The last
number is bumped when the implementation of existing symbols changes, the middle
one when when new symbols are added, and the first one when an incompatible
change happens, i.e. symbols are removed or changed incompatibly. Lower numbers
are reset to zero whenever a higher one changes.)  The SOVERSION corresponds to
the major number and does not change in the case under discussion.

As Gordon wrote, our rpm dependency generation logic does not care about the
minor or patch numbers.
