## [5.4.3] - 2021-08-13
### Fixed
- Fixed an issue where `304 NOT_MODIFIED` responses to SDK polling mode requests would be considered error responses. This could cause the completion on a `identify` request to not complete, and gave erroneous connection information data and logging output. 
- Fixed a crash when attempting to cache flag data containing variation JSON values containing a JSON `null` value nested within a JSON array.
