This seems to be a minor update that brings small bug fixes

Nokia Lumia owners will be pleased to know that Microsoft has just started the rollout of a new Windows Phone 8 GDR3 Developer Preview update for their devices.

Esphoneblog reports that this is a two-step update that brings the smartphone’s software to version 8.0.10521.155. The first update to be pushed OTA (over the air) features build number 8.0.10517.150, but after applying it, a new one will be available for download (8.0.10521.155).

We have confirmation that the Windows Phone 8 GDR3 update arrives on Nokia Lumia Developer edition devices with Preview for Developers running on it.

Keep in mind that the update is pushed OTA (over the air) in stages, so it may take a while until it reaches all compatible Windows Phone devices.

Microsoft has yet to issue an official changelog for this update, but given the small size, we suspect that it only brings some minor bug fixes and improvements.
