Errors with jsonschema 3.2.0 - not with 4.6.0

[SnarkBoojum]

While trying to upgrade the Debian package for atd in Debian from 2.4.1 to 2.9.1, I had issues:

(cd _build/default/atdcat/test && /usr/bin/python3 -m jsonschema schema.json -i data.json)
3.3: False schema does not allow 3.3
-77.22: False schema does not allow -77.22
['Thing', 99]: ['Thing', 99] is not valid under any of the given schemas
['!!!', ['a', 'b']]: ['!!!', ['a', 'b']] is not valid under any of the given schemas
1.1: False schema does not allow 1.1
1: False schema does not allow 1
2.2: False schema does not allow 2.2
2: False schema does not allow 2
['Some', 10]: ['Some', 10] is not valid under any of the given schemas
['Some', 88]: ['Some', 88] is not valid under any of the given schemas

and it turns out it was due to Debian currently using jsonschema 3.2.0 -- things worked with jsonschema 4.6.0 (not yet readily available in Debian).

So you should probably document which jsonschema version you actually depend on, to avoid bogus reports of errors in atd.
