- `defer()` can set deferred events on `.GlobalEnv` to facilitate the
interactive development of code inside a function or test. Helpers
`deferred_run()` (and `deferred_clear()`) provide a way to explicity
run and clear (or just clear) deferred events (#76, @jennybc).
- `with_connection()` now works when existing objects or connections
exist with the same names (#120)
- `with_makevars()` now uses `tools::makevars_user()` to determine the
default user makevars file (#77, @siddharthab).
- `with_options()` no longer uses `do.call()`, so optiosn are not
evaluated on exit (#73, @mtmorgan).
- `with_package()` no longer has the `help` argument (#94, @wendtke).
- `with_package()` now does not try to detach the package if it is
already attached before calling `with_package()` (#107)
- `with_preserve_seed()` now restores `.Random.seed` if it is not set
originally (#124).
- Add `with_rng_version()` and `local_rng_version()` functions to
change the version of the RNG (#90, @gaborcsardi).
- `with_svg()` documentation now is consistent across R versions (#129)
- Add `with_timezone()` and `local_timezone()` functions to change the
time zone (#92, @gaborcsardi).
- `with_tempfile()` and `local_tempfile()` now delete recursively
directories on exit (#84, @meta00).
