version 1.1.2

Changes since 1.1.1:
- Document the pre-existing panic in `wait_timeout` if
  `Instant::now() + timeout` overflows.

version 1.1.1

Changes since 1.1.0:
- Duct now uses a global `Mutex` to prevent pipe inheritance bugs caused
  by the lack of `pipe2` on macOS. (The Python version of Duct relies on
  `close_fds=True` instead, but the Rust standard library has no
  equivalent.)

version 1.1.0

Changes since 1.0.0:
- Added the `Handle::wait_timeout` and `Handle::wait_deadline` methods.
  These are gated by the `timeout` feature, which is enabled by default.
  Windows supports these timeouts natively, but on Unix this requires
  handling `SIGCHLD`.
- Fixed a bug with setting or removing non-uppercase env var names on
  Windows. Duct previously uppercased all env var names passed to its
  API, but not names coming from the system environment, which caused
  mismatches. See #119.

version 1.0.0

Changes since 0.13.7:
- The API is stabilized as-is, and most callers won't need to make any
  changes.
- Fixed a bug where `Handle::try_wait` could block indefinitely if a
  child process had exited but a longer-lived grandchild process was
  keeping its IO pipes open and its IO threads running (i.e.
  `stdin_bytes`, `stdout_capture`, or `stderr_capture`). Commit 04c2c8c.
- `Handle` now does lazy cleanup of leaked zombie children. If a child
  has not exited by the time its `Handle` is dropped, that child gets
  added to a global list. Whenever any Duct function is about to spawn a
  new child, it polls each child in the leaked list and cleans up any
  that have exited. This strategy is copied from Python's `subprocess`
  module. `ReaderHandle` contains a `Handle` internally and does the
  same cleanup.
- With that new cleanup mechanism in place, `Handle::kill` and
  `ReaderHandle::kill` no longer wait on child processes to exit. This
  avoids obscure edge cases (FUSE filesystems, debugger pauses) where
  waiting after `SIGKILL` could still block indefinitely.
- Duct no longer kills your child processes in any circumstance other
  than when you call `.kill()`. Previously Duct would kill child
  processes when dropping a `ReaderHandle`, or in rare pipe spawning
  error cases.

version 0.13.7

Changes since 0.13.6:
- Avoid unnecessarily dup'ing standard file descriptors. This unbreaks
  some use cases where those descriptors might not exist at all, like
  Windows services. See #99.

version 0.13.6

Changes since 0.13.5:
- Dependency updates only.

version 0.13.5

version 0.13.2

Changes since 0.13.1:

- Debug output for `Expression` is more concise.
