update_docs() now updates the package version as
well as altdoc version in the footer.
The NEWS or Changelog file included in the docs now automatically links issues, pull requests and users (only works for projects on Github).
Vignettes are now always rendered by use_*() or
update_docs(). Therefore, the argument
convert_vignettes is removed. Previously, they were only
rendered if their content changed. This was problematic because the code
in a vignette can have different output while the vignette in itself
doesn’t change (#37, #38).
New argument custom_reference in
use_*() and update_docs(). If it is a path to
a custom R file then it uses this file to build the “Reference” section
in the docs (#35).
