Hello everyone,

I planned on upgrading EPICS from 7.0.7 to 7.0.8 in our build system,
but had some errors in our PV access tests.

Apparently, in 7.0.8, the 'pvget my:pv -M json' now returns JSON5:

    my:pv:name
{value:42.0,alarm:{severity:0,status:0,message:""},display:{description
:"My PV description"}}

Where before in 7.0.7, it returnd standard JSON:

    my:pv:name
{"value":42.0,"alarm":{"severity":0,"status":0,"message":""},"display":
{"description":"My PV description"}}

Was this a conscious choice? I don't see the change in the release
notes. I think for interoperability, standard JSON would be better.

Thanks a lot, and have a great day!
