v0.5.0

CRAN Release v0.5.0

- Packrat now supports both of BiocManager and BiocInstaller (as used for
  discovering the Bioconductor repositories active for the current project).
  BiocManager will be used for R >= 3.6.0; BiocInstaller will be used otherwise.

- The R option `packrat.dependency.discovery.disabled` can be set to TRUE to
  disable dependency discovery in projects. This can be useful if you find
  Packrat's dependency discovery is slow (as it can be in projects containing
  a large number of R Markdown files). (rstudio#513, @ras44)

- The scheme used for hashing packages that enter the Packrat cache has
  changed -- now, a defined ordering of fields is used when hashing a
  package's DESCRIPTION file. Note that this implies a package may need to be
  re-cached on restore, in the case that its hash has changed. This change
  should not affect any existing packages in the cache. (rstudio#505, @aronatkins)

- `packrat::with_extlib()` now works with no `packages` provided;
  both with and without this option, the new behavior is that `expr`
  is executed in an environment where the original (not packrat)
  library search path is in place.

- A project is now only considered 'packified' if it has both a Packrat
  lockfile as well as the associated autoloader in the project `.Rprofile`.

- Calling `packrat::init()` on a project that already contains a Packrat
  lockfile no longer attempts to re-snapshot and restore the project.

- Packrat now supports R packages available on BitBucket, courtesy of a PR from
  @mariamedp. (rstudio#481)

- Added the project option `symlink.system.packages`: users can now configure
  whether base R packages from the system library are symlinked into a private
  library `packrat/lib-R`. Disabling this can be useful if you intentionally
  want Packrat to use packages that have been installed into the system library.

- Fixed an issue where attempts to snapshot could fail when
  the R libraries live on a network drive.
