No: releasing a new version of the GPL makes no difference, and neither
does releasing a new version of Emacs.  What makes a difference is when
a package is modified to make use of features that are only provided by
an Emacs that uses a new license (e.g. Emacs-23, released under the
GPLv3+, adds many new features which are not available in any GPLv2+
emacsen).
