acme-v2.js
==========
A framework for building Let's Encrypt v2 (ACME draft 11) clients, successor to `le-acme-core.js`.
Built [by request](https://git.coolaj86.com/coolaj86/greenlock.js/issues/5#issuecomment-8).
This is intented for building ACME API clients in node.js.

otherwise known as Let's Encrypt v2 (or v02).
* ACME draft 11

* ACME draft 11
* Let's Encrypt v2
* Let's Encrypt v02
API
===
The predecessor (le-acme-core) supports Let's Encrypt v1 (or v01), which was a
[hodge-podge of various drafts](https://github.com/letsencrypt/boulder/blob/master/docs/acme-divergences.md)
of the ACME spec early on.
This API is an evolution of le-acme-core,
but tries to provide a better mapping to the new draft 11 APIs.
* ACME early draft
* Let's Encrypt v1
* Let's Encrypt v01
Status: Almost stable, but **not semver locked**.
This library maintains compatibility with le-acme-core so that it can be used as a **drop-in replacement**
and requires **no changes to existing code**,
but also provides an updated API more congruent with draft 11.
Patch versions will not introduce breaking changes,
but may introduce lower-level APIs.
Minor versions may change return values to include more information.

* v1.0.7 - improved error handling again, after user testing
* v1.0.6 - improved error handling
* v1.0.5 - cleanup logging
* v1.0.4 - v6- compat use `promisify` from node's util or bluebird
* v1.0.3 - documentation cleanup
