Description:
Hibernate uses one instance of query cache for all cached queries. In some cases user may want to store query results in the different caches instead of using "main" one.

Here is a description of the major changes 
1. There were 2 caches in QueryCache.java - query cache itself and timestamp cache. The last one was moved to the separate class, because we didn't divide that cache. 
2. cacheRegion property was added to the Query and QueryParameter classes 
3. There is a new method, getQueryCache(String cacheRegion) in SessionFactoryImpl. It returns query cache, stored in the internal map or creates new one and puts it there. It also destroys all these caches in the close() method. 
4. There are some minor changes, too. For example, default query cache's region name was changed to net.sf.hibernate.cache.QueryCache. This was done as object cache's region name equals to classname and there may be conflict in naming if someone has QueryCache class (without package) in his code.
