5.01
- Doc fixes

5.00
- This version adds Elasticsearch 5.x compatibility, and makes it
  the default.
- It also adds deprecation logging which logs to STDERR by default.

- The Hijk backend will not work with Elasticsearch 5.x until this bug
  is fixed: https://rt.cpan.org/Ticket/Display.html?id=118425

BREAKING CHANGES:
- The 0.90, 1.x, and 2.x compatible clients no longer ship by default.
  You should install one of the following:
      * Search::Elasticsearch::Client::2_0
      * Search::Elasticsearch::Client::2_0::Async
      * Search::Elasticsearch::Client::1_0
      * Search::Elasticsearch::Client::1_0::Async
      * Search::Elasticsearch::Client::0_90
      * Search::Elasticsearch::Client::0_90::Async
- The code has been reorganised so that all client-related modules
  are under the S::E::API_VERSION::Client namespace.
  This includes S::E::Bulk and S::E::Scroll.
- Plugin authors note: the format for the API in ...Role::API has changed.
- S::E::Cxn::HTTP has been rolled into S::E::Cxn as Elasticsearch
  no longer supports other protocols.
