# 2.1.1
This version has no user visible changes.
# 2.1.0
* `unzip_process()` now does not fail randomly on Windows (#60).
* Now all functions handle Unicode paths correctly, on Windows
as well (#42, #53).
* `unzip_process()` now works when R library is on different drive
than `exdir` on Windows (#45)
* zip functions now have a `mode` argument to choose how files and
directories are assembled into the archive. See the docs for
details.
* zip functions now have a `root` argument, zip changes the working
directory to this before creating the archive, so all files are
relative to `root`.
* `zip()` and `zip_append()` are not deprecated any more, as it was
hard to achieve the same functionality with the other zip functions.
The canonical form [1] of an R package Makefile includes the
following:
- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
needed), and CATEGORIES.
- HOMEPAGE is not present but defined in math/R/Makefile.extension to
refer to the CRAN web page describing the package. Other relevant
web pages are often linked from there via the URL field.
This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.
