Microsoft have released a new set of updates for the HoloLens. The update is “2019-05B for Windows 10 Version 1809 for x86-based Holographic Devices” and takes be build from 17763.438 to 17763.502.

Microsoft haven’t posted what the details of the update is yet but it’s probably the usual security updates. It is not the 1903 update which Microsoft are due out release for PCs later this month, I don’t expect we will see that on the HoloLens.
