Breaking change from version 3.6.* to 3.9.*

[NinjaCross]

I'm using version 3.6.3, and I implemented my own inheritor of IEntityFrameworkSecondLevelCacheProvider
Inside that implementation, I'm using IReaderWriterLockProvider.
I've tried to upgrade to 3.9.*, but the code doesn't compile anymore, because IReaderWriterLockProvider has been removed.

Breaking changes are normal/expected for major version bumps, but are very unusual for minor versions bumps.

My suggestion is to comply with Semantic Versioning 2.0.0 and:

1. Reintroduce IReaderWriterLockProvider interface and it's implementor in 3.* versions, in order to keep uniform compatibility
2. Bump up the current release to major version to 4.*, so that user knows that there are breaking changes

I don't want to do that, and you have no right to tell me what to do.
