Good question, I'm thinking about an update of Minera but there are too many factors that delay me.

For example, USB mining is almost gone forever, I don't think we will see new USB devices in future and that was the main feature of Minera (manage USB devices).

All the current profitable hardware are networked and many of them don't use anymore official Cgminer but closed forks that you can't do anything with it (example S9).

So networked miners should require manual hard work to be connected to Minera (if you are able to do it).

The main big feature everybody requests me almost every day is the Ethereum support, but again we lack a lot on possibility to monitor it. Claymore miner is closed source and if I understand it hasn't any API to get stats.

Using standard miner is complex and running it via PHP could be a pain, and you cannot run a GPU device on a RPI so you should run it on Linux but I don't see a "simple" way to get it on board.

And finally I don't like anymore PHP I abandoned coding with it since some years so I should rebuild Minera from scratch and I have no time to do that.

That said I'd like to do a 0.7.1 just to fix something and update the code to support for example PHP7.0 but nothing more and I really don't know when.
