6.0.1
---------------------
- Version 6 RTM, for integration to ASPNET Core 2.1 IHttpClientFactory
6.0.0-v6alpha
---------------------
- Publish as strong-named package only (discontinue non-strong-named versions)

- Allow user-created custom policies
5.6.1

- (.NET40Async package changes only)
5.0.3 RTM
---------------------
- Refine implementation of cancellable synchronous WaitAndRetry
- Minor breaking change: Where a user delegate does not observe cancellation, Polly will now honour the delegate's outcome rather than throw for the unobserved cancellation (issue 188).
5.0.2 alpha
---------------------
- .NETStandard1.0 target: Correctly state dependencies.
- .NETStandard1.0 target: Fix SemVer stamping of Polly.dll.
- PCL259 project and target: Remove, in favour of .NETStandard1.0 target. PCL259 targets are still supported, via .NETStandard1.0 target.
- Mark Polly.dll as CLSCompliant.
5.0.1 alpha
---------------------
- Add a .NETStandard1.0 target.
5.0.0 alpha
---------------------
A major release, adding significant new resilience policies:
- Timeout policy: allows timing out any execution
- Bulkhead isolation policy: limits the resources consumable by governed actions, such that a faulting channel cannot cause cascading failures.
- Fallback policy: provides for a fallback execution or value, in case of overall failure
- PolicyWrap: allows flexibly combining Policy instances of any type, to form an overall resilience strategy.
Other changes include:
- Add PolicyKeys and context to all policy executions, for logging and to support later introduction of policy events and metrics.
- Add CancellationToken support to synchronous executions.
- Add some missing ExecuteAndCapture/Async overloads.
- Remove invalid ExecuteAsync overloads taking (but not making use of) a CancellationToken
- Provide .NET4.0 support uniquely through Polly.NET40Async package
- Retire ContextualPolicy (not part of documented API; support now in Policy base class)
- Discontinue .NET3.5 support
