Subscription example fails to compile

[nicolaiunrein]

I tried to update my code and had an issue with subscriptions. I then tried to run the example and it seems to give me the same error:

I forgot to update the parser version. 😂

There is no easy-to-use tool to batch update the version number.

I updated the version number, and after cargo update it was compiled. 😁
