Moved the caching stores from ActionController::Caching::Fragments::* to ActiveSupport::Cache::*. If you're explicitly referring to a store, like ActionController::Caching::Fragments::MemoryStore, you need to update that reference with ActiveSupport::Cache::MemoryStore [DHH] Deprecated ActionController::Base.fragment_cache_store for ActionController::Base.cache_store [DHH] All fragment cache keys are now by default prefixed with the 'views/' namespace [DHH] Added ActiveRecord::Base.cache_key to make it easier to cache Active Records in combination with the new ActiveSupport::Cache::* libraries [DHH] Added ActiveSupport::Gzip.decompress/compress(source) as an easy wrapper for Zlib [Tobias Luetke] Included MemCache-Client to make the improved ActiveSupport::Cache::MemCacheStore work out of the box [Bob Cottrell, Eric Hodel] Added config.cache_store to environment options to control the default cache store (default is FileStore if tmp/cache is present, otherwise MemoryStore is used) [DHH]
