PBIRS build 15.0.1122.101

The changelog says there are various bug fixes in the last build, what are these changes?

  • Version: 1.27.9794.1532 (build 15.0.1122.101), Released: October 26, 2026
    • Various bug fixes.

Since upgrading to PBIRS September 2026, ReportingServices no longer opens images through API using its execution account and I was hoping that updating to the newest build may correct the issues I'm facing. There must be a proper change log somewhere, various bug fixes is not really saying a lot.

    Hello MikBrePer​,

    I had a look at the official PBIRS changelog, and unfortunately, Microsoft hasn't published an itemized breakdown of the fixes. So there's currently no documented confirmation that the execution account or external image retrieval issue has been addressed.

    I'd recommend checking the RSPowerBI and ReportingServicesService logs for authentication or HTTP errors when retrieving images. Also, I suggest to verify that the execution account can still access the image URLs, particularly if they require Windows authentication.

    I'd suggest raising a Microsoft support case referencing both builds and requesting confirmation of whether this regression is included in the latest fixes, rather than upgrading Production without verification.
