Cache

• Fixed reading an intermittent null weak/soft value during a concurrent write (#​568)

Cache

• Added triggering cache maintenance if an iterator observes an expired entry for more aggressive eviction (#​487)
• Improved eager eviction of an added or updated entry if it exceeds the cache's maximum weight
• Deprecated CacheWriter. Please use asMap computations or an eviction listener instead
