This is a BETA release. While we don't expect that some of the more mature technologies underlying it, like ZFS or FreeBSD 10.3, will corrupt your data or crash in mysterious ways, there have been a lot of changes to everything from replication to sharing, so at the very least you may encounter significant and confusing differences (with very few "seat belts" to help you) between 9.x and this release. We do not recommend using 10-BETA for production purposes! Use Google Chrome to talk to 10-BETA! It is the ONLY supported browser at this time, as the release notes clearly state. Any other browser is more or less guaranteed to fail (looking especially at you, Safari!). Cross-browser compatibility is harder than it should be and will be a goal for the BETA2 release. As it also says in the Release Notes, upgrades from 9.x are not supported at this time. They will be for RELEASE, but not for this BETA. Upgrades are tricky, and we just need more time to work through all the various scenarios before we can promise anything. ;) You should only do fresh installs of 10-BETA for evaluation purposes. Docker container support is especially rough right now, and will be one of our biggest areas of emphasis in the coming weeks, so please don't expect it to be equivalent to the existing 9.x "plugin" system. Docker will eventually offer access to a far greater ecosystem of canned applications, as well as interoperability with the enormous DevOps community using it, but what we can offer right now is basically only a "technology demonstrator", so please set your expectations accordingly! Update often (using the built-in updater)! We expect to get a lot of bug reports and to fix a lot of them in the next 24 hours, to say nothing in the days that follow!

Hi folks!Yes, after a rather exhausting BETA release cycle and over 3 months of work involving more than 830 tickets resolved we are very proud and excited to finally ship FreeNAS 10 BETA!Attached to this post are some fancier Release Notes rather than the usual wall of text we post into the forum. A short video walk-through has been posted on YouTube (see below) which covers some of the basics of what you should expect to see. We would also like to draw your attention to the following points, some of which are also in the "Important Notes" section at the end of the Release Notes which we hope everyone will read!All that said, we think the sheer quantity of enhancements and new technologies in 10-BETA have been worth the wait, and we hope you will dedicate at least some of your valuable time to evaluating it and sending us bug reports on the issues you find as we work our way towards the next public release. The FreeNAS team have also been very transparent in working out in the open with our bug tracker and our nightly builds , so those who wish to "follow along" and send us feedback will, we hope, find the process to be enlightening as well as rewarding!It usually takes a little while for http://freenas.org/download to get updated, so please check out the CDN site directly if you don't see it as an option on the main FreeNAS web page.We sincerely hope you enjoy playing with this release as much as we enjoyed creating it! :DThe FreeNAS Development Team
