# callr 3.7.0
* Reporting errors is much faster now (#185).
* The `user_profile` option of `r_vanilla()` defaults to `FALSE` now (#194).
* It is now possible to set R environment variables (`R_ENVIRON_USER`,
`R_PROFILE_USER`, etc.) via the `env` argument (#193).
# callr 3.6.0
* callr now supports starting an R process with a different architecture,
so on Windows 64-bit R can start a 32-bit R background process, and
vice-versa (#95).
* callr now handles symbolic arguments properly, and does not evaluate them.
E.g. `callr::r(function(x) x, list(quote(foobar)))` works now (#175).
* `callr::r_session` does not leak file descriptors now in the sub-process
(#184).
