4.8.0

New

• Dummy failure exception should include reasons for failure (#1397)

Fixed

• Misleading exception message when failing to create a Dummy (#1367)
• Parameterless constructor is always tried when creating fake classes, even if there isn't one (#1395)
• Custom attributes, additional interfaces, and constructor parameters silently dropped when creating a Fake delegate (#1353)
  The fix is to fail fast when these options are used to create Fake delegate. This may cause some tests to fail on Fake creation, rather than letting the erroneous usage go unnoticed.

Additional Items

• Stop mentioning removed-in-4.0.0 record/playback feature in the docs (#1402)
• Show actions after all call specifications in docs (#1342)
• Set new NuGet API key (#1400)
