From time to time, we may make feature preview releases available. Driver and software preview releases differ from new GA releases and testcase packages in several ways. Consider testcase packages first:

• Packages uploaded to the testcase files area are made available to specific customers to evaluate the effectiveness of various changes to our GA versions, usually to address one or more issues reported in specific trouble tickets. Feedback from the affected customer(s) is requested when we provide these packages, and these links are limited to only the custmer(s) involved in the related ticket(s), not for general use, and as always, not for sharing with other users.
• Sometimes, we may go through several testcase revisions. Usually changes which have been vetted through this process will end up in the next GA of the package. Once the GA is released, all customers with related subscription access to the new package will be able to download and install it.
• Testcase packages are almost always time-limited, and the remaining time will be prominently displayed in the banner during bootup or for other software, at program start. If a new GA of the package is not available when nearing the expiration, simply follow-up in the ticket to request a refresh.

In contrast, preview releases serve a different purpose and are subject to different terms of use:

• Preview releases are made available to all customers with related subscription access.
• Preview releases generally are not updated (one preview is provided before GA).
• Preview releases may be time-limited. If a preview release is time-limited, that does not mean that another preview will be made available.
• If a time-limited preview release has expired and a GA version has not yet been released, it may be necessary to uninstall it.
• No trouble tickets are accepted for problems with preview releases. These are not beta tests. A preview may simply be feature-limited version of what would otherwise be considered finished software, or it may be a preview of as-yet-unfinished software that will be coming soon. Because these releases are previews – and may not be fully functional – reports of missing functionality, unexpected behavior, etc. are not relevant and will not be addressed. Please read the documentation that comes with the preview for a description of its particular limitations.
• Preview releases may be completely broken or disabled by a subsequent update of another related GA package. As an example, if installing a preview release of a network driver, and later updating the network stack package, that preview release driver may cease to function. This is not unexpected behavior, and not a software fault. To continue to use the preview, simply return the system to its previous state, wait for the GA release of the driver, and then update the driver and the rest of the stack.
• No feedback via email or tickets is requested for preview releases. They are for your benefit and use only, and intended to provide a sample of what is to come.

In the near future, we hope to bring preview releases for various works in later stages of development.

All previews will be available through the ArcaOS Support and Maintenance Subscription, However, some preview packages may not be available through the Arca Noae OS/2 & eCS Drivers and Software Subscription, so now may be a good time to consider moving up to ArcaOS.
