------------------------
PyDM 1.7 is intended to be the final minor version in the 1.0 series. The next non-bugfix release will almost definitely be 2.0, which will be centered around big changes to the flow of data between PyDM plugins and widgets. This will allow us to support sources of _structured data_, where multiple pieces of data are all sent as a single structure. This will allow us to support a whole new set of control system protocols, like [EPICS7's PVAccess](https://epics-controls.org/resources-and-support/base/epics-7/).
This will be a big overhaul, and there will be some breaking changes to the way things work - mostly in the data plugin department, but a few other places too. We'll publish migration guides to help you get any custom data plugins and widgets you have up in running in 2.0. Another change to be aware of is that we will be ending support for Python2.7 - all v2.0-and-up releases will only support Python 3.6 and higher.
Our plan is to have a separate '2.0' branch of the PyDM repository available (probably with pre-release tagged versions) for a few months, and let the user community try it out before finally merging it in and releasing 2.0 proper. Stay tuned!
