Dear @BraTS2026Participants, In response to numerous requests from participating teams, we have _extended the deadline_ for Docker and short paper submissions with one week. You now have **until July 30th** to continue developing your model, uploading your validation results, and submitting your manuscript (the previous deadline was July 23rd). Please note that this is a **strict, hard deadline**, and there will be no further extensions. We would like to remind you that a valid submission includes the following components: - A submitted containerized version of your algorithm as a Docker image - A paper describing the methods and results submitted on the [OpenReview platform](https://openreview.net/group?id=MICCAI.org/2026/Challenge) - A signed Copyright form, which will be provided to you by the challenge organizers All other dates in the BraTS timeline will remain the same. Cordially, BraTS Organization Team
