-All methods (`then`, `catch`, `cancelled` and `finally`) are optional. If specified, the closure related to the `finally` method will always be called regardless whether the task was cancelled or not, whether there was an error or not.

 ## Non failable tasks
 If you read the framework's code you will find the `NonFailableTask<Value>` class. This kind of task cannot fail (sort of). In fact it may fail, but it should not.
 
-The main difference from the failable task class is that you do not have to use the `try` keyword when awaiting for non failable task results. A non failable task cannot be cancelled either.

-## Observers and conditions
-The previous version had observers and conditions based on Session 226 of WWDC 2015 (“Advanced NSOperations”). This turned the framework unnecessarily complex.

-Observers and conditions may be reimplemented in a future release or as a separated framework. No guarantees, though.
+In version 4.0 the framework has the notion of "dependencies" and a new kind of "conditions" was implemented. Observers may reappear in a future release. No guarantees, though.
