withr 2.3.0

Deprecations

• local_tempfile() argument new is deprecated, in favor of returning the path to the new tempfile.
  calls like local_tempfile("xyz") should be replaced with xyx <- local_tempfile() in your code (#141).

New features

• New local_seed() function and local_preserve_seed() functions to correspond to with_seed() and with_preserve_seed() (#139).

• New local_tempdir() function added to create a temp directory (#140)

• local_*() functions now take dots (...), which can simplify calls in some cases, e.g. you can now use local_options(foo = "bar") rather than local_options(c(foo = "bar")).

Minor improvements and fixes

• defer() now throws an error if an error occurs in the deferred expression (#148)

• with_file() and local_file() can now work if the file is actually a directory (#144).
