## [2.2.1] - 2021-01-13
### Changes
* Now uses the much faster fnv1
* Now md5 hashs the keys to help distribute hosts more evenly in some
cases.
## [2.2.0] - 2019-07-09
### Added
* Added `SetLogger()` to pass in a logrus entry for logging peer errors
* Added `DeregisterGroup()` to remove an existing group cache
### Changes
* Fixed race condition in `Remove()`
## [2.1.0] - 2019-06-10
### Changes
* `Get()` now returns immediately when context is done during a groupcache peer
conversation. Previously `Get()` would call the `Getter` with a done context.
## [2.0.0] - 2019-06-04
### Changes
* Now using golang standard `context.Context` instead of `groupcache.Context`.
* HTTP requests made by `httpGetter` now respect `context.Context` done.
* Moved `HTTPPool` config `Context` and `Transport` to `HTTPPoolOptions` for consist configuration.
* Now always populating the hotcache. A more complex algorithm is unnecessary
when the LRU cache will ensure the most used values remain in the cache. The
evict code ensures the hotcache does not overcrowd the maincache.
* Changed import paths to /v2 in accordance with go modules rules
* Fixed Issue where `DefaultTransport` was always used even if `Transport` was
specified by the user.
### Removed
* Reverted change to associate `Transport` to `httpGetter`, Which caused a data
race. Also discovered `DefaultTransport` has per address connection pooling
only when the request was a success, which is sufficient for most use cases.
## [1.3.0] - 2019-05-23
### Added
* Added `Remove()` method to `Group` to purge a key from the group.
## [1.1.0] - 2019-04-10
### Added
* Sinks can now accept an expire time
* Changed import path to mailgun/groupcache
## [hash 5b532d6fd5efaf7fa130d4e859a2fde0fc3a9e1b] - 2019-01-29
