The FreeNAS development team is delighted to announce the general release of FreeNAS 9.1.0. This release offers massive improvements to the usability, extensibility, stability, and performance of FreeNAS. Everything from the web user interface, plugin management system, base operating system, ZFS file system, and even the source control used to manage the project have been substantially improved. With FreeNAS 9.1.0, iXsystems sets a new level of excellence and power in open source storage solutions. FreeNAS 9.1.0-RELEASE can be downloaded from http://www.freenas.org/download.html Major parts of the Web User Interface have been overhauled to add functionality and improve usability. The volume creation interface has been completely replaced with a new wizard that assists the user in creating the most ideal storage pool and optimal setup for the number of disks available, also helping those unfamiliar with ZFS to make correct early configuration decisions and avoid painful rebuilds later. The encryption interface has also been modified to emphasize the correct steps for safely and securely encrypting a newly created pool. The FreeNAS plugin system has been completely revamped to cover a wider variety of use cases, from the needs of the beginner to the expert user. Plugins can be installed from a user-configurable central plugin repository as well as uploaded manually through the easy web interface. Multiple jails and jail types, including jails for FreeNAS plugins, PC-BSD ports, and conventional FreeBSD packages, are now supported. FreeNAS also uses the Warden system from PC-BSD and features a completely redesigned user interface. With more choices to extend FreeNAS than ever before, end-users and developers alike will find this to be the most powerful and extensible version ever released! FreeNAS now includes ZFS feature flags, bringing it in line with the future of ZFS development. This upgrade lets FreeNAS benefit from the most up-to-date open source work on ZFS such as LZ4 compression, which allows compressed datasets to operate at near real-time speed. With ZFS feature flags, every project can pick and choose which features to add to ZFS and implement new ones to be shared with the community. Other improvements to ZFS in FreeNAS 9.1.0 include TRIM support to get better performance from solid-state drives, enhanced drive failure notification, improved memory use, and reliability enhancements. The underlying operating system in FreeNAS 9.1.0 has been updated to FreeBSD 9-STABLE, a conservative development branch that offers updates in advance of the next FreeBSD RELEASE version. This allows FreeNAS to benefit from the very latest updates and features. iXsystems engineers have also brought in additional performance and stability enhancements from the even more advanced FreeBSD 10-CURRENT branch, where improvements from outside FreeBSD are often introduced. By working with the latest stable code available, enhancements and bug fixes developed for FreeNAS can more easily be passed back to upstream projects where they will benefit users across the open source community. Behind the scenes, FreeNAS is now using git as its primary source control system. This switch is intended to make it easier for outside developers to make substantive contributions to FreeNAS. Along with the release of FreeNAS 9.1, we are also proud to announce that the FreeNAS source code is now hosted on Github.com as well as Sourceforge.net, introducing it to an even wider developer community. Github users can now see, follow, and fork the repository at github.com/freenas/freenas. We look forward to your pull requests!
