That’s why several tracks are reopening for a bonus CFP! If you missed the original submission period, this is your final chance to share your open source project and experiences at COSCUP 2026. ⚠️ Please note: Not all tracks are reopening, and this bonus CFP follows a “may close early at any time” policy. Once certain tracks receive enough proposals or complete their review process, submissions may close before the deadline. If you have a topic in mind, don’t wait until the last day 👀
