processx 3.8.4

• No changes.

processx 3.8.3

• *printf() format strings are now safer (#379).

processx 3.8.2

• The client library, used by callr, now ignores SIGPIPE when writing
  to a file descriptor, on unix. This avoid possible freezes when a
  callr::r_session subprocess is trying to report its result after the
  main process was terminated. In particular, this happened with parallel
  testthat: r-lib/testthat#1819

processx 3.8.1

• On Unixes, R processes created by callr now feature a SIGTERM
  cleanup handler that cleans up the temporary directory before
  shutting down. To enable it, set the PROCESSX_R_SIGTERM_CLEANUP
  envvar to a non-empty value.

processx 3.8.0

• processx error stacks are better now. They have ANSI hyperlinks for
  function calls to their manual pages, and they also print operators
  better.

• processx now does not mark standard streams as close-on-exec on Unix,
  as this causes problems when calling system() from an R subprocess
  (r-lib/callr#236).

v3.7.0

• New functions for creating portable FIFOs and Unix socket connections.
  See conn_create_fifo(), conn_create_unix_socket() and
  vignettes/internals.Rmd for documentation. These functions are currently
  experimental.

v3.6.1

• processx now closes file unneeded file descriptors when redirecting
  the standard output and error, in the client file.

• processx errors now do not have rlang_error and rlang_trace classes,
  because they are actually not compatible with rlang errors and traces.

v3.6.0

• processx now gives better error messages, and better stack traces.

v3.5.3

• run() now sets stderr to NULL in the result (instead of an empty
  string), if the standard error was redirected to the standard output.
  This also fixes an error when interrupting a run() with a redirected
  standard error.

• processx now does not fail if the current working directory contains
  a non-ASCII character on Windows, and getwd() returns a short path
  for it (#313).

v3.5.2

• run() now does not truncate stdout and stderr when the output
  contains multibyte characters (#298, @infotroph).

• processx now compiles with custom compilers that enable OpenMP (#297).

• processx now avoids a race condition when the working directory is
  changed right after starting a process, potentially before the
  sub-process is initialized (#300).

• processx now works with non-ASCII path names on non-UTF-8 Unix platforms
  (#293).
