v0.9.1

• Bugfix: LruCache::contains_key should take &self and not move the entry as
  though it is accessed.
• Add basic CursorMut API to HashMap (thanks @olebedev!)
• Bump hashbrown dependency to depend on a version of hashbrown past a
  downstream zerocopy dependency.
• Don't depend on default features of hashbrown, removes allocator-api2
  dependency.

v0.9.0

API incompatible change: Don't panic in reserve and try_reserve in cases where a rehash is needed. Previously would panic, adds the proper bounds on reserve methods to do a rehash (previously bounds were missing, and reserve would result in panics). (Thank you @cuviper)

v0.8.4

Now builds with #![no_std].
