On June 28, 2006, [[Theodore Ts'o]], the principal developer of ext3,<ref>[https://lkml.org/lkml/2006/6/28/454 "Theodore Ts'o": Proposal and plan for ext2/3 future development work]. LKML. Retrieved on 2013-06-22.</ref> announced an enhanced version, called ext4. On October 11, 2008, the patches that mark ext4 as stable code were merged in the Linux 2.6.28 source code repositories, marking the end of the development phase and recommending its adoption.
In 2008, Ts'o stated that although ext4 has improved features such as being much faster than ext3, it is not a major advancement, it uses old technology, and is a stop-gap; Ts'o believes that [[Btrfs]] is the better direction, because "it offers improvements in scalability, reliability, and ease of management".<ref>{{cite web
