+- Redox: Add `dirfd`, `VDISABLE`, and resource consts ([#4660](https://github.com/rust-lang/libc/pull/4660))
+- Redox: Add more `resource.h`, `fcntl.h` constants ([#4666](https://github.com/rust-lang/libc/pull/4666))
+- Redox: Enable `strftime` and `mkostemp[s]` ([#4629](https://github.com/rust-lang/libc/pull/4629))
+- Unix, Windows: Add `qsort_r` (Unix), and `qsort(_s)` (Windows) ([#4677](https://github.com/rust-lang/libc/pull/4677))

+- Linux: Correct the config for whether or not `epoll_event` is packed ([#4639](https://github.com/rust-lang/libc/pull/4639))
+- Tests: Replace the old `ctest` with the much more reliable new implementation ([#4655](https://github.com/rust-lang/libc/pull/4655) and many related PRs)
