## Deprecations
### Simpler resolvers
All the resolvers in graphene have been simplified.
Prior to Graphene `2.0`, all resolvers required four arguments: `(root, args, context, info)`.
Now, resolver `args` are passed as keyword arguments to the function, and `context` argument dissapeared in favor of `info.context`.
Before:
```python
my_field = graphene.String(my_arg=graphene.String())
def resolve_my_field(self, args, context, info):
my_arg = args.get('my_arg')
return ...
```
With 2.0:
```python
my_field = graphene.String(my_arg=graphene.String())
def resolve_my_field(self, info, my_arg):
return ...
```
And, if you need the context in the resolver, you can use `info.context`:
```python
my_field = graphene.String(my_arg=graphene.String())
def resolve_my_field(self, info, my_arg):
context = info.context
return ...
```
### AbstractType deprecated
AbstractType is deprecated in graphene 2.0, you can now use normal inheritance instead.

and `context` and `info` will only be passed if the function is annotated with it.
