Future of Tapestry

Hi all,

I discover recently Tapestry and it's for me a great Framework but my boss tells me that his end is near ...

and the github https://git1-us-west.apache.org/repos/asf?p=tapestry-5.git;a=summary has less and less activities

Could you tell me if this Framework will continue to be maintained ? When the next version 5.5 will be delivered ?

If not, what framework could remplace it with same fonctionnalities ? and responsive interface 

Vaadin ? Spring boot ? Grails ? ZK ? Others ?

Thanks in advance
