> I am hoping to release ConcurrentLinkedHashMap v1.2 by the end of the week. This task
is optional, but gives you the opportunity to canary the library and provide any final feedback.
There are currently 285 tests (some threaded) plus a load test, so reliability-wise I'm fairly
confident.
> This release has numerous performance improvements. See the change log for details.
> It also includes a few useful features that may be of interest,
>  - Snapshot iteration in order of hotness (CASSANDRA-1966)
>  - Optionally defer LRU maintenance penalty to a background executor (instead of amortized
on caller threads)
