3.6.0 - 2016-10-31
This release reverts Hypothesis to its old pretty printing of lambda
functions based on attempting to extract the source code rather
than decompile the bytecode. This is unfortunately slightly inferior
in some cases and may result in you occasionally seeing things like
lambda x: <unknown> in statistics reports and strategy reprs.
This removes the dependencies on uncompyle6, xdis and spark-parser.
The reason for this is that the new functionality was based on
uncompyle6, which turns out to introduce a hidden GPLed dependency
- it in turn depended on xdis, and although the library was licensed
under the MIT license, it contained some GPL licensed source code
and thus should have been released under the GPL.
My interpretation is that Hypothesis itself was never in violation
of the GPL (because the license it is under, the Mozilla Public
License v2, is fully compatible with being included in a GPL licensed
work), but I have not consulted a lawyer on the subject. Regardless
of the answer to this question, adding a GPLed dependency will
likely cause a lot of users of Hypothesis to inadvertently be in
violation of the GPL.
As a result, if you are running Hypothesis 3.5.x you really should
upgrade to this release immediately.
