== Fixes

* Fixed TreeMap.split (#4, #79)
* Fixed Option.fromNull javadoc (#73)
* Fixed Try javadoc (#91)
* Fixed stack overflow in TreeMap.update (#97)
* Fixed concurrency issue with P1.memo (#105)

== Breaking Changes

* #93 added the F0 interface which P1 implements.  This could break code where the _1 method for a new P1 called the method 'f' outside P1's scope.  Making P1 implement F0 means that P1 now has an 'f' method which hides the visibility of the previously visible outer 'f'.  You can fix this by using P.lazy, as per the example below.

[source,java]
----
// old code
return fromString(s.some()).append(new P1<Stream<Character>>() {
    public Stream<Character> _1() {
        return f(reader); // call outer f, 4.3 code change breaks this
    }
});

// new code
return fromString(s.some()).append(P.lazy(u -> f(reader))); // outer f now visible
