The extended file system (ext), was released in April 1992 as the first file system using the VFS API and was included in Linux version 0.96c.
But it still had problems: there was no support of separate timestamps for file access, inode modification, and data modification. As a solution for these problems, two new filesystems were developed in January 1993 for Linux kernel 0.99: xiafs and the second extended file system (ext2), which was an overhaul of the extended file system incorporating many ideas from the Berkeley Fast File System.

Since 2009, the Linux kernel supports a journal-less mode of ext4 which provides benefits not found with ext2, such as larger file and volume sizes. ==History== The early development of the Linux kernel was made as a cross-development under the MINIX operating system.
The latest patch for Linux 3.0 was released in August 2011 and provides multicore and High memory support.
