7.0.0-preview4

Bug fixes:

• Add nullables to the properties in WsFederationMessage. See issue #2240 for details.
• Fix regression where JsonWebToken.TryGetPayloadValue() was not compatible with dictionary types. See issue #2246 for details.
• Fix regression where dictionary claims added to SecurityTokenDescriptor.Claims are no longer correctly serialized. See issue #2245 for details.
• Fix regression with a Y2038 bug. See issue #2261 for details.

Performance improvements:

• Use optimistic synchronization in JsonWebToken.Audiences. See PR for details.
• Reduce allocations when enumerating over collections. See PR for details.

Documentation:

• Fix description for JWT X5tS256 field.

@kevinchalet A lot of the issues you opened were addressed in preview4. We are thinking the next release could be the GA version 7.0.0 by end of next week (week of Sept 4). Any feedback or testing you want to do before then would be much appreciated.

Thank you.

I gave it a try and I can confirm most of the issues are indeed fixed.

I opened #2281 to track a potential last issue.

I don't see it mentioned, but I guess #2244 is fixed, right?

I'll give it a try and let you know how it goes.

[jennyf19]

Yes, that's fixed. Missed that one. I'll update the release notes.
