Version 1.1.0 (2016-01-25)

Version 1.2.0 (2016-03-08)

Add two new default methods ord_subset_min_by_key and ord_subset_max_by_key for OrdSubsetIterExt to mimic std library.

Allow *_by_key() functions for iterators and slices when the items aren't OrdSubset. Only the keys need to be. This changes the extension traits' bounds, therefore technically a [breaking change] (cause for major version bump)
Add long overdue ord_subset_sort_by_key() and ord_subset_binary_search_by_key() for slices

OrdVar::new_unchecked() is no longer marked unsafe. Incorrectly constructed OrdVars can cause crashes and surprising behaviour but no memory unsafety
In slice sorting, uphold sort stability for values outside total order.

Add sort_unstable* variants, following the std library additions in 1.20. Technically a [breaking change].
Generalized traits so that .ord_subset_binary_search* works on immutable slices and anything else that implements AsRef<[T]>, but not AsMut<[T]>. Fixing this major oversight is also technically a [breaking change].
#![no_std] support with new opt-out feature std Stable sorts are unavailable in no_std mode. OrdSubset implementations for f32, f64 with no_std require the unstable feature of this crate (impls readded in 3.1 without unstable).
Stabilized _rev() variants

Add OrdSubset impls for all Ord intrinsics, including arrays and tuples up to an arity of 32 and 12 respectively as well as slices.
Add OrdSubset impls for f32, f64 in no_std mode without requiring unstable.
Add new feature ops for overloading operators for OrdVar<T> for anything that T is overloaded for. Checks whether result can be ordered. This can be deactivated with unchecked ops.

Code tarball doesn't unnecessarily contain files with executable bit set anymore.
