We will consider bug fixes from the community or support requests from existing customers up until this date.

Please make appropriate plans if you are using this library in production, e.g.:

* Dedicate personnel to maintaining your own internal copy of the library.
* Consider a commercial library such as the one offered by [Step Function I/O](https://stepfunc.io/products/libraries/dnp3/).

You can read about this decision in these blog posts:

Overview
========

Opendnp3 is a portable, scalable, and rigorously tested implementation 
of the [DNP3](https//www.dnp.org) protocol stack written in C++11. The library 
is designed for high-performance applications like many concurrent TCP
sessions or huge device simulations. It also embeds with a small footprint on Linux.
