See IdentityModel7x for the updates on this much anticipated release.

7.0.0-preview5

Bug fixes:

• Improve log messages. See PR #2289 for details.
• In AadIssuerValidator return a ValueTask<string> instead of a Task<string>. See Issue #2286 and PR [https://redirect.github.com/Change Task to ValueTask. AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet#2287] for details.
• Deprecate int? JwtPayload.Exp, .Iat, and .Nbf. See issue #2266 for details, #92, and #1525.

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.
• Fix a regression where claims with multiple values are incorrectly serialized. See #2244 for details.

Performance improvements:

• Remove sync-over-async pattern with JsonWebTokens.ValidateToken, which when in the hot path can lead to threadpool starvation. See issue #2253 for details.
• Perf testing using brenchmark dotnet and crank, similar to aspnetcore, to better gauge requests per second perf impacts. See issue #2232 for details.
• 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.

Fundamentals:

• Improvements to the build script to accommodate .NET's source-build requirements. See PR for details.

7.0.0-preview3
