Dunai 0.12.3, dunai-test 0.12.3, and bearriver 0.14.8

[ivanperez-keera]

Hi everyone! I'm happy to announce release 0.12.3 of dunai. It is accompanied by a matching release of dunai-test and bearriver.

This is a maintenance release. The main changes are in bearriver, which now provides a matching FRP.BearRiver.Loop (akin to Yampa's).

As always, this release comes 2 months after the prior release. Feel free to try it, and open new discussions for any issues you see.

There is an ongoing discussion on an alternative implementation of ListT. Although the proposed changes were not merged as part of this release, there are plans to incorporate them as soon as possible.
