  Close 3555

* New check: ``consider-using-generator``

  This check warns when a comprehension is used inside an `any` or `all` function,
  since it is unnecessary and should be replaced by a generator instead.
  Using a generator would be less code and way faster.

  Close 3165

* Add Github Actions to replace Travis and AppVeyor in the future
   ```
   
  
  
   ### 2.6.1
   ```
