What is the default limit on Datastore?

[Joshua Fox]

If I use withDefaults(), what is the limit on a Datastore query? I don't see it in the JavaDocs

This StackOverflow answer  seems to say that it used to be 1000 , but was changed. What is it now?

'withDefaults()' is just a new FetchOptions(), and FetchOptions() has no default 'limit' as seen in the code. 

Even in the JavaDocs it explains that 'getLimit()' returns null if nothing has been set. The only default that is set is the chunk size. In the code it shows it being set to '20', but I think this has been since increased to ~300 (or ~1000).
