I have just uploaded a new version of my engine Surprise. I expect a small improvement compared to 4.3-beta1, especially because I implemented SEE for QS move ordering. But as always, there was not enough time for testing so I fully rely on the customers

For any tournaments, I would recommend to switch to this new version if it is still possible. For WBEC I hope that round 4 has not yet started so the upgrade is still allowed.
If there were someone out there who wants to support me with an even faster windows build (e.g. one of BH, DC, JA) I would not say "no"
