Obviously not, how could it be? 1. The person does not know your
code, 2. Then it would not be possible ever to introduce any
not-backward-compatible changes in a library API.

Your code makes use of a particular version of a library. If
there is a newer non-API-compatible version of the library that
you want to make use of, the porting effort is of course on your
part. However noone forces you to use the newer version.

In case you are worried about the version your software works
with becomes unavailable, you might package it alongside your
software. Keep in mind that you need to supply the sources to the
library in case you provide precompiled versions. For details see
the license text, the GPL FAQ, and when in doubt a lawyer.

Best,
