    - Clarify separation of sync and async policies (breaking change)
    - Enable extensibility by custom policies hosted external to Polly
    - Enable collection initialization syntax for PolicyRegistry
    - Enable cache policies to cache default(TResult) (breaking change)
    - Restore Exception binary serialization for .Net Standard 2.0

    - Bug Fix: Context.PolicyKey behaviour in PolicyWrap (issue 510)

    - Bug Fix: Context.PolicyKey behaviour in PolicyWrap
    - Bug Fix: CachePolicy behaviour with non-nullable types
    - Enhancement: WaitAnd/RetryForever overloads where onRetry takes the retry number as a parameter
    - Enhancement: Overloads where onTimeout takes thrown exception as a parameter

    - Version 6 RTM, for integration to ASPNET Core 2.1 IHttpClientFactory

    - Publish as strong-named package only (discontinue non-strong-named versions)
    - Add .NetStandard 2.0 tfm
    - Provide .NET4.5 support via .NetStandard 1.1 tfm
    - Discontinue .NET4.0 support
    - Remove methods marked as deprecated in v5.9.0

    - Allow Timeout.InfiniteTimeSpan (no timeout) for TimeoutPolicy.
    - Add .AsPolicy<TResult> and .AsAsyncPolicy<TResult> methods for converting non-generic policies to generic policies.
    - Per Semver, indicates deprecation of overloads and properties intended to be removed or renamed in Polly v6.

    - Add a new onBreak overload that provides the prior state on a transition to an open state
    - Bug fix: RelativeTtl in CachePolicy now always returns a ttl relative to time item is cached
    - Minor cache fixes
    - Add ability to calculate cache Ttl based on item to cache
    - Allow user-created custom policies

    - Extend PolicyWrap syntax with interfaces

    - Add ability to handle inner exceptions natively: .HandleInner<TEx>()
    - Allow WaitAndRetry policies to calculate wait based on the handled fault
    - Add the ability to access the policies within an IPolicyWrap
    - Allow PolicyWrap to take interfaces as parameters
    - Bug fix: set context keys for generic execute method with PolicyWrap

    - Fallback delegates can now take handled fault as input parameter.

    - Make ISyncPolicy<TResult> public
    - (Upgrade solution to msbuild15)

    - Fix ExecuteAndCapture() usage with PolicyWrap   
    - Allow Fallback delegates to take execution Context
    - Provide IReadOnlyPolicyRegistry interface

    - Add PolicyRegistry for storing and retrieving policies.
    - Add interfaces by policy type and execution type.
    - Change .NetStandard minimum support to NetStandard1.1.

    - Allow different parts of a policy execution to exchange data via a mutable Context travelling with each execution.

    - Update NETStandard.Library dependency to latest 1.6.1 for .NetStandard1.0 target.  Resolves compatibility for some Xamarin targets.

    - Bug fix: Prevent request stampede during half-open state of CircuitBreaker and AdvancedCircuitBreaker.  Enforce only one new trial call per break duration, during half-open state.
    - Bug fix: Prevent duplicate raising of the onBreak delegate, if executions started when a circuit was closed, return faults when a circuit has already opened.
    - Optimisation: Optimise hotpaths for Circuit-Breaker, Retry and Fallback policies.
    - Add NoOpPolicy: NoOpPolicy executes delegates without intervention; for eg stubbing out Polly in unit testing.

    5.0.4 pre
    - (.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
