DragonFly BSD 5.6.2 released: significant HAMMER2 improvements

2 min read

DragonFly is an operating system and application environment designed as a continuation of the FreeBSD-4.x family. These operating systems and Linux can be classified as the same category, because they are based on UNIX concepts and application programming interface. DragonFly is a branch of this road of development, it can be said, is a BSD to a different from the FreeBSD-5 series of new directions and the development of the opportunity.

DragonFly version 5.4.1 has significant HAMMER2 improvements (meta-consistency protection for snapshots and crashes, better on-media topology), better WLAN interface handling, and improved WLAN connection with dhcpcd(8).
