Hi Is Power BI Report Server officialy released product or is this preview\beta only.Is there any one on this forum that is using this in their production environment? Jaco

It's a feature-driven release rather than a date-driven release, so we don't have a fixed date. We want to have support for large files (now that you can import data into your *.pbix files), scheduled data refresh and DirectQuery for various data sources, and thorough testing. As soon as we have that, we'll release. While we can't predict the precise date, we know we're more than a few days away, so it probably won't be October. At the same time, we don't intend to wait until the end of Q4 if we don't need to. As soon as it's ready, we'll release. Just trying to be as transparent as possible. Hope it helps at least a little!

The June/July release is an officially released product and we are indeed using it in production (pretty small scale at the moment but it's expanding rapidly)

As Anonymous said; the June 2017 release is the current generally-available (GA) release for production use, while the August 2017 Preview is a preview/beta of our work in progress toward our next GA release, targeting Q4 CY 2017.

Thanks for the information. What is the product version of the current GA product? I have installed what I thought to be the GA version (14.0.600.301). But this version won't let me upload any report.I get this error "We can't open this Power BI report because it contains an unsupported data source connection or embedded data. This version of Power BI Report Server supports Power BI reports that connect live to SQL Server Analysis Services Or Azure Analasis services"

That is indeed the June 2017 (GA) version. That version supports connections to Analysis Services only. Support for data imported from other data sources is a work in progress in our August 2017 Preview.
