Another cycle, another release, more final comment periods! The libs team discussed this past triage meeting what APIs should be stabilized for the 1.9 release on May 26, 2016. This is a pretty exciting list of APIs with lots of goodies! Each issue has entered a cycle-long **final comment period** for discussion about the API being stabilized. If you’ve got reservations or want to show support, please feel free to do so by commenting on the issues!

- [`std::raw`](https://github.com/rust-lang/rust/issues/27751) - deprecate the slice-related bits
- [the `str_char` feature](https://github.com/rust-lang/rust/issues/27754) - mixture of stabilization/deprecation

Any chance we could see stabilisation of [`HashSet`](https://doc.rust-lang.org/std/collections/struct.HashSet.html)'s `get`, `replace` and `take` methods? I’ve been using them in [hashindexed](https://crates.io/crates/hashindexed) for a while.

Yup, that’s up for FCP this round under “set recovery methods”: [https://github.com/rust-lang/rust/issues/28050](https://github.com/rust-lang/rust/issues/28050)
