    ---------------------
    - (.NET40Async package changes only)

    5.0.3 RTM
    ---------------------
    - Refine implementation of cancellable synchronous WaitAndRetry

    - .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

    4.3.0
    ---------------------
    - Added ability for policies to handle return results.  Optimised circuit-breaker hot path.  Fixed circuit-breaker threshold bug.
