3.0.0

⚠️ Breaking change!!!

Cache 3 features multiple public API changes and brand new features implemented as a feedback to the input we got. We also did some internal framework refactoring that will make it easier to read the code, test and contribute 🎉

• Cache is renamed to SpecializedCache in order to resolve conflicts with the name of the framework.
• SyncCache and SyncHybridCache wrappers were removed because SpecializedCache and HybridCache are now sync by default. But it's also possible to perform async cache operation using the new Async API: https://github.com/hyperoslo/Cache#hybrid-cache
• As a part of the new Sync API you can use subscript to easily set/get/remove objects: https://github.com/hyperoslo/Cache#specialized-cache
• Now it's possible to update cache directory attributes with setDiskCacheDirectoryAttributes method and use setFileProtection method to enable data protection: https://github.com/hyperoslo/Cache#enabling-data-protection
• There is new Coding protocol which works in the same way as NSCoding, but can be used for
  Swift structs and enums: https://github.com/hyperoslo/Cache#coding
• totalDiskSize() method is added to get total cache size on the disk #94
• CryptoSwift is replaced with more lightweight SwiftHash framework: #88
