Hello everyone and welcome to another Unrayed Monthly Digest for the month of September. And I'm your host, Stefano Partida. No, you're not. Yeah, yeah, this is my show. Let's get started.

Headline Features Overview

SPEAKER_00 0:20

In the previous digest, I had already announced to you that Unraid 7.2 beta 3 was available. However, on October 1st, release candidate 1 became available. So instead, we're gonna talk about that. With this latest release, of course, they have added the responsive web UI, which you would have seen in the betas, but if you wanted to wait till the release candidates, that is now available. There's also the built-in Unraid API where the community drives their feature requests. And there's also a bounty program where you, yes, yourself, can actually develop code for this API and get a monetary award and or community recognition.

Storage Upgrades and Filesystem Support

SPEAKER_00 0:59

RAID Z expansion has also been added so you can grow the size of your Z pool one at a time without taking your array offline. There's expanded file system port for ext and TFS and XFAT. This is great. So if you have a Windows system that uses NFTS, you can now take that drive and put it in your Unraid array and it will also be parity

Security and UI Enhancements

SPEAKER_00 1:20

protected. SSO and OIDC login has been enabled in the Web UI, so you can use your Unray.net account or any third-party OIDC provider. There have been dashboard and web UI enhancements like the CPU usage stats now come from the API. New notifications and management. There's a bell icon that will display those. Numerous fixes to alignment and pop-ups and dark mode.

VM and Networking Improvements

SPEAKER_00 1:52

For the VM and networking improvements, we have virtual sound card support now, better multi-monitor support, VM manager, now warns if PCI hardware assignments change and darker IPv6 custom networks now support ULAs.

Hardware Support and Deprecations

SPEAKER_00 2:04

A couple of other cool features that have been added, one of which is EMMC support. That's really cool. So that means you could have really fast storage for a cash pool, probably. And then we also have the uh or unready has the ability now to auto-authorize Thunderbolt 4 devices. So that's pretty nice to have. Also don't forget Riser FS is deprecated now and that will no longer be supported. You should see a notification in the web UI if you are running that. And hopefully none

Safe Update Guidance

of you are. And of course, before updating from the betas to the release candidates or really at all, always update your Unraid plugins, especially the Unraid Connect plugin and any NVIDIA driver plugins that you might be using, because there could be some conflicts there when upgrading versions. So be sure to upgrade your plugins

New USB Creator for Linux

SPEAKER_00 2:51

first. A new USB creator tool has been released, so that will make deployments much easier now. But wait a minute, you're saying we've always had one. Well, not on Linux, you haven't, and now it's totally available. So anyone that is using Linux can now use a tool to make deploying Unraid that much easier to your USB
