| 76 | +## Sponsors |
| 77 | +- Dataiku provided the space and some of the food, as well as all of the coffee. |
| 78 | +- The scikit-learn consortium organized the sprint, paid for the lunch, the travel and accommodation expenses. |
| 79 | + |
| 80 | +## Topics covered at the sprint |
| 81 | +- PR #13649: [Monotonic constraints for Tree-based models](https://github.com/scikit-learn/scikit-learn/pull/13649) |
| 82 | +- Discussed the vision/future directions for the project. What is important to keep the project relevant in the future. |
| 83 | +- Should we share some points beyond the vision statement? |
| 84 | +- Thomas F will try and create a vision statement |
| 85 | +- Discussed what people are keeping an eye on with a two year time scale in mind in terms of technology and developments that are relevant. |
| 86 | +- Tim: keep improving our documentation (not just expanding it but also “gardening” to keep it readable) |
| 87 | +- Tim: increase active outreach and communication about new features/improvements and other changes. A lot of cool things in scikit-learn are virtually unknown to the wider public (e.g. Hist grad boosting being on par with lightgbm in terms of performance, …) |

| 90 | +### What is next? |
| 91 | + |
| 92 | +We are discussing co-locating with OpenML in 2024 in Berlin to organize another developers' sprint. |
