Now working on version 2.0.0
Resolve IProgress<T> issues by providing System.IProgress<T> for .NET 3.5 and using Microsoft.Bcl for .NET 4.0 (fixes #67)
Include CancellationTokenSourceExtensions in .NET 4.5 builds for binary compatibility across all .NET 4.x builds (fixes #70)
Implement CancellationTokenSourceExtensions for .NET 4.5 since the .NET implementation does not provide the same GC guarantees as this library
Include WebRequestExtensions in all builds (fixes #72)
Include StreamExtensions in all builds (fixes #73)
Added historical documentation for the 1.1 release
Set a timeout on a unit test method so an implementation that doesn't implement support for the WebRequest.Timeout property doesn't hang
Add a minimal set of StreamExtensions tests to ensure inclusion of StreamExtensions in all builds does not result in a StackOverflowException
