0.6.7:
[bug] Fixed issue in the CacheRegion.get_or_create_multi() method which was erroneously considering the cached value as the timestamp field if the CacheRegion.invalidate() method had ben used, usually causing a TypeError to occur, or in less frequent cases an invalid result for whether or not the cached value was invalid, leading to excessive caching or regeneration. The issue was a regression caused by an implementation issue in the pluggable invalidation feature added in 38.
0.6.6:
[feature] Added method CacheRegion.actual_backend which calculates and caches the actual backend for the region, which may be abstracted by the use of one or more ProxyBackend subclasses.
[bug] Fixed a condition in the Lock where the “get” function could be called a second time unnecessarily, when returning an existing, expired value from the cache.
0.6.5:
[bug] Fixed import issue for Python 3.7 where several variables named “async” were, leading to syntax errors. Pull request courtesy Brian Sheldon.
