Dear Mehmet, We are an Open Source project. This means that all of our source code is always publically available - no matter the stage of a release. There is no need to ask for early access. Just go to https://github.com/qgis/QGIS and use the master branch to create your own builds. If you want to use a ready to use installer from download.qgis.org just use the OSGeo4W installer and select QGIS 3.99 (qgis-qt6-dev-full). I believe there are also other methods to get hold of a current stage through Github artefacts.
Hope this helps, Andreas On Wed, 22 Oct 2025 at 10:21, Mehmet DUMAN (UZAY) via QGIS-Developer < [email protected]> wrote: > I hope this message finds you well. > > > My name is Mehmet Duman, and I am currently working at TÜBİTAK UZAY (The > Space Technologies Research Institute of TÜBİTAK) in Turkey.
