  * added `CacheInterface`, which provides stampede protection via probabilistic early expiration and should become the preferred way to use a cache
  * added sub-second expiry accuracy for backends that support it
+ * added support for phpredis 4 `compression` and `tcp_keepalive` options
  * throw `LogicException` when `CacheItem::tag()` is called on an item coming from a non tag-aware pool
  * deprecated `CacheItem::getPreviousTags()`, use `CacheItem::getMetadata()` instead
  * deprecated the `AbstractAdapter::createSystemCache()` method
