Hello @Ali_Imam 

Thank you for reaching out to us and welcome to the TP-Link community.

I honestly do not have an answer for that. Can I know why you require an update? Is there an issue with the current firmware? Or is there any specific requirement for new firmware?

Please note that Typically FW updates are only provided If there is a need for it, such as patching a security flaw that is found, repairing a bug, or adding a feature. If an FW is solid and there are no needs for an update it could be some time between updates. This doesn't mean that the product is not being supported or anything like that, rather it is just that the router is solid and we do not know of any specific concerns at that particular time.
