2.0.0

• Drop support for Node 4
• New behavior for expirationPoll option on MemoryStore. The expiration poll feature is now opt-in. By default there will be no memory scan to proactively remove key values. Passing a number or null for expirationPoll will behave as before. Passing a value of true will use a default of 15000ms.
• The DefaultRequestExecutor is now used by default, if no request executor is provided.

1.2.0

• Adds a default request executor that will retry requests when rate limit exceptions have occurred. Please see the README for full documentation. This executor is opt-in for now, but will be used by default in the 2.0 release.
