Twitter announced recently new API paid version, can you tell us how we migrate from here

Hi,

I am in this space. Currently from code base i see that we are using this library and thinking whether we might be impacted with Twitter recent API changes.

We are happy to take paid version if required for our application internally talking to procurement team, but can guide me how do I migrate it using same library .

I think current library is using 1.1 version which is deprecated?
