6.1.0
---------------------
- 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
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)
- Add .NetStandard 2.0 tfm
- Provide .NET4.5 support via .NetStandard 1.1 tfm
- Discontinue .NET4.0 support

5.9.0
---------------------
- 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.
5.8.0
---------------------
- 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
5.7.0
---------------------
- Minor cache fixes
- Add ability to calculate cache Ttl based on item to cache
- Allow user-created custom policies
5.6.1
---------------------
- Extend PolicyWrap syntax with interfaces
5.6.0
---------------------
- 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

- Add CachePolicy: cache-aside pattern, with interfaces for pluggable cache providers and serializers.
- Bug fix: Sync TimeoutPolicy in pessimistic mode no longer interposes AggregateException.
- Provide public factory methods for PolicyResult, to support testing.
- Fallback delegates can now take handled fault as input parameter.

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

- 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
