Customers are encouraged to use the latest available version of an SDK to take advantage of new features, enhancements, performance improvements and bug fixes. Updating your applications about every six months is advised but each project/company has different release cycles. 


Part of the regular release cycle should consider including new minor releases of the PubNub SDKs. Major version releases should be considered as part of a larger release plan. Please review our SDK EOL (end of life) policy for full details on support for older SDK versions.


You can follow the github repo of the SDK(s) you are using to get regular updates about bug fixes and upcoming feature releases.
