It's certainly possible to create a release that doesn't change
libwireshark or libwiretap. We've done it a few times the past (e.g.
1.0.16 fixed some Windows DLL hijacking flaws), but that case is very rare.

(In case you're wondering why I'm being stubborn about this, the
Wireshark release checklist is currently *3 pages long*. Adding manual
steps makes a long process even longer and makes it more error prone.)

I propose running it as far in advance of each release as possible. :)
Having something we could run as a Buildbot step (that is, a makefile
target or a shell, Python, or Perl script) would be fantastic.
