Sage 2.10.4 was released on ?????. For the official, comprehensive release notes, see the HISTORY.txt file that comes with the release. For the latest changes see[http://sagemath.org/announce/sage-2.10.4.txt sage-2.10.4.txt]. Among many other things that were done, we have increased documentation substantially, and fixed many bugs. Of course, this list is incomplete; see the release notes for more details.

Memory leaks exposed by modular symbols

Michael Abshoff, Martin Albrecht, Burcin Erocal, Willem Jan Palenstijn, Clement Pernet, William Stein:

• memory leaks exposed by modular symbols functionality [this ticket is a composite of numerous other memleak fixes merged over a *7 month* period. Modular forms are an excellent way to expose memory leaks in pretty much every algebraic component of Sage and all known issues there are now finally fixed]

Graph theory: chromatic polynomial

An algorithm originally written in C by Gordon Royle has been adapted to replace the old slow method. This algorithm uses a cut and merge algorithm to recursively compute the chromatic polynomial, and is written in Cython.
