`Ok(())` immediately without doing any calls to the underlying operating
system. [#104]
- Use the `kern.arandom` sysctl on NetBSD. [#115]

[#100]: https://github.com/rust-random/getrandom/pull/100

## [0.1.11] - 2019-08-25
### Fixed
- Implement `std`-dependent traits for selected targets even if `std`
feature is disabled. (backward compatibility with v0.1.8) [#96]

## [0.1.10] - 2019-08-18 [YANKED]

## [0.1.9] - 2019-08-14 [YANKED]
### Changed
- Remove `std` dependency for opening and reading files. [#58]
- Use `wasi` isntead of `libc` on WASI target. [#64]
- By default emit a compile-time error when built for an unsupported target.
This behaviour can be disabled by using the `dummy` feature. [#71]
