+We instantiated a more refined mechanism for startup messages, to avoid

+Somewhat more detailed, in the prior regime, suppose we had pkgs pkgA and pkgB on
+CRAN, pkgB importing the NAMESPACE of pkgA via depends, and both pkgs pkgA and pkgB
+had startup messages including version information, and pkgB used the reference
+output <pkgB>-Ex.Rout.save as a unit test for pkgB. Then, whenever we submitted an
+updated version of pkgA to CRAN, we had to also submit a new version of pkgB to CRAN
+regardless whether we had changed anything in pkgB, because of the changed version
+information in the startup message of pkgA which showed up in the reference output
+when pkgA was attached at loading pkgB.
+
+To avoid this, by default our startup messages no longer issue version information

+ }%
+Also, from version 1.0.0 on, we show a hint on how to obtain version information of all attached packages,
+regardless of whether these use start-up messages managed by this packages; i.e.; through sessionInfo().
+This hint is only shown once per session, but can also be switched on and off through
+\code{options("StartupShowHint_sessionInfo")} set to \code{TRUE} or \code{FALSE}, respectively.
