CHANGES (p.zmq-async.5.2.1.doc.CHANGES)

Remove dependency on StdInt (#121, @andersfugmann)
Silence warnings about const char* when writing to the inside of an allocated string value (#116, @Leonidas-from-XIV)

Use unix sockets in tests to avoid permission problems when running in a sandbox environment.
Make monitor test more reliable by explictly waiting for each event to arrive.

Fix EINVAL when attempting to get the curve encryption keys (#85, #86, #91)
Do not depend on configurator anymore (#96)
Depend on v0.11 versions of Jane Street packages to not fail on makedev issue. This requires us to drop support for OCaml 4.03 (#93)

Implement Msg.gets (#87, #90)
Improve support for OCaml 4.08+ (#83, #89)
Properly allocate right size of caml block (#88)
Update build config to use new dune syntax
Remove configurator in favor of dune.configurator. This removes the build time dependency on the configurator and base packages.

Change build system to use jbuilder instead of oasis. This also adds proper support for pkg-config installed zmq.
Import zmq-async and zmq-lwt. The old bindings async-zmq and lwt-zmq are now deprecated.
Refactor zmq-async and zmq-lwt to be supported out of a single code base. This regularizes the interface, and dramatically improves and stability.
Add support for and reading & writing bigarrays. This interfaces allows the user to reduce needless copying of packets sent by the bindings.
Rename module ZMQ to Zmq.

Add threading example by Stavros Polymenis
Minor addition to API documentation
Remove OCaml version requirement in opam package (strictly not part of this release, but still)

Fixes a generic problem with deallocating resources though finalisers. As a result no resources are automatically released though finalisers. However a warning will be printed to stdout if resources are leaked
Include oasis autogenerated files, removing the dependency on oasis when installing
