4.0.2 release notes

release packages

3.5 packages

Mark for 3.3

3.1.3 Rel

Remove 3.1.1; push 3.1.2 add missing files.

* Correct documentation

* Update docs
* Add example in tests for enhanced use

Reduce target frameworks from `netstandard2.0;netstandard1.6;netstand…

…ard1.3;net20;net35;net40;net45;net451;net452;net462;net47;net472` to `netstandard2.0;netstandard1.6;net20;net35;net40;net452;net462;net472`

This drops netstandard1.3 only, nothing else should be affected, but netstandard1.3 is pulling in 1.6 framework code. Both packages are signed now. Yey me

Enhanced Verification Changes

* Adds HashType to EnhancedVerify and Verify.
* Reorganises main signature of ValidateAndReplacePassword to oldkey params / new key params and a simplified overload for basic replace (non enhanced).
* Adds tests.
* Stop EnhancedHashPassword being used with HashType.None
