[4.12.1] - 2020-03-20
Changed:
- Improved the performance of the in-memory flag data store by using an immutable map that is atomically replaced on updates, so reads do not need a lock.
- Improved the performance of flag evaluations when there is a very long user target list in a feature flag or user segment, by representing the user key collection as a Set rather than a List.
- Updated OkHttp version to 3.12.10 (the latest version that still supports Java 7).
