new for version 1.35.1
======================
* vulcanexample() loads the dataset into an environment of its own instead
  of into the function frame, which is what "no visible binding for global
  variable 'vobj'" was reporting. The value returned is unchanged
* DESCRIPTION uses Authors@R, and its Description field ends as a sentence
* The RStudio session directory and the R command history are no longer
  tracked by git, and .Rhistory is no longer shipped inside the package
  tarball. Both were already named in .gitignore, which does not apply to
  files that are already tracked
* Corrected the title of the vulcansheet() man page
