I've just pressed the submit button on the GSoC 2024 application form. All we can do now is keep our fingers crossed that we're accepted this year.
In the meantime, we can continue to update and refine the project ideas list:
https://github.com/dlang/project-ideas
So any submissions to the issues list there are welcome. I expect either Razvan or I will be updating the projects in the root directory after our monthly meeting this week.
