pgRouting 2.1 why not available on PostgreSQL 9.5?

Is there any reason you guys decided to package pgRouting 2.0.1 instead of
the newer pgRouting 2.1.0 with PostgreSQL 9.5.
If not would it be a bother to replace (or add pgRouting 2.1).

After running:

yum install pgrouting_95


I get this when I run

SELECT * FROM pgr_version();


version |       tag       | build |  hash   | branch | boost
---------+-----------------+-------+---------+--------+--------
 2.0.0   | pgrouting-2.0.1 | 5     | 40ad51f | master | 1.41.0


My selfish reasons for wanting pgRouting 2.1 is two fold

1) A lot of work has gone into 2.1.0 to clean up and fix issues present in
2.0 and a lot of that work I contributed to and my good friend Vicky Vergara
put her heart and soul into.

2) The book that Leo and I are writing - http://locatepress.com/pgrouting
is focusing on pgRouting 2.1 and above.
There is enough of an API change between 2.0 and 2.1, that sadly this book
is not going to be of much use to people running pgRouting 2.0.
This is quite depressing.
