Hej Matt and all

> We've verified that the problem happens with Python 3.7.6, but not with Python 3.7.5.  It also appears that pyepics works with Python 3.8.0.

I couldn’t get that to work (on travis)

conda install -c conda-forge pyTest
[]
UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
  - pyepics -> python[version='2.7.*|3.6.*|>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']
Your python: python=3.8

(If you want, I can send you the whole travis log,
 or a link to it).

I didn’t manage to convince travis to use python3.7 and not 3.8
On the other hand, 3.8 seems to be the future.

Is there any chance to look at this, some day ?
Or should I open an issue on github ?
Or is there anything else I can help with ?

>  I don't think anyone has tested it with Python 3.8.1, I suspect that may fail too as it was released at the same time as 3.7.6.   As it happens, it looks like updating an Anaconda Python 3.7 environment will now upgrade to Python 3.7.6.
