What's Changed

• Corrected nullable markup on IIndex<K,V>.TryGetValue() since it may return null on failure.
• Composite services can now be keyed (#1458 - thanks @syko9000!)
• Packages for core Autofac are no longer published to MyGet. Instead, builds are now available from GitHub Packages This also means the actual packages themselves won't be manually attached to the release - you can get them from the package source now.
