By now, all of you have probably received the results of this year's Google Summer of Code. I want to congratulate you all for the work that you have done this year, students and mentors alike.

We have had 4 projects this year:
1. EXCEPT ALL  and INTERSECT ALL operations - Ruihang Xia

2. INSERT ... RETURNING - Rucha Deodar

3. UPDATE ... RETURNING - Miroslav Koberskii

4. Support for indexes on expressions - Alexey Mogilyovkin

Implementing these projects certainly took a lot of effort. The first one is already merged within MariaDB and the rest will probably follow, after a bit more polishing. The MariaDB community would be grateful if you stuck around to watch over your projects, extend them and improve them over time.

I am sure there was a lot to learn from this experience. Now that you have gotten a feel to what it means to contribute significant features to MariaDB you are in a great position to help others! In this sense, I encourage you to keep being active in the community and share what you have learned. :)

Thank you for a great summer!
