As many of you certainly are aware by now, I have been officially hired by ReactOS Deutschland e.V. to develop the graphical version of the 1st-stage ReactOS installer (“1st-stage GUI setup”). During this first month (September 2023), my goal was to partly sync the code of the setupapi.dll module with Wine’s.

Hello ReactOS followers and enthusiasts! It has been quite a long time since we published the 101th newsletter and so far no further updates have been posted since then. While the ReactOS Twitter account does provide announcements, posts about working applications and such from time to time, much of what is happening with the project as a whole isn’t mentioned. Most of what we are going to talk about is the current situation with releases and overall ReactOS development.
