5.1.0

• Add support for primitive type 'bytes'
• Add of_<driver>_exn for deserializing of Driver.t
• Dont depend on ppxlib for the runtime

• Support result type
• Require ppx >= 0.9.0 => support ocaml 4.10 (Thanks kit-ty-kate)

Major rewrite

This release features a major rewrite, and complete compatibility with Ppx_deriving_yojson, to allow Ppx_protocol_conv_json be a drop in replacement.

The deserialization functions now returns a result type. The previous exception style behavior is still available in function suffixed with _exn.

This release is not backward compatible with previous releases.

A short list of changes since version 4.0.0:

• Add option make make lazy type indeed lazy
• Add option to mangle variant names
• Refactor tuple, variant and record code to be more efficient
• Reduce amount of closures in generated code
• Support nativeint
• Remove superfluous rec flag from generated code
• Cache partial results for recursive types
• Fix signatures for parameterized types
• Create helper module for tuple, record and variant.
• Add strict option
• create t_to_driver and t_to_driver_exn
• Move some documentation to wiki pages
• Add a TLDR to the README, including dune build instructions
• Allow core < v.013
• Switch to use alcotest
• Expose constructor to driver error type for custom parsers. (@paurkedal)
