UPDATE (2022-05-05, 9:00pm UTC): the patch is now available, please refer to this post for details
We usually release our monthly patch by the end of the month. By now, you would expect that our 5.5.2 patch (April 2022) should have been released. Unfortunately, a slight technical issue prevents us from releasing this on time.
Our engineers are working diligently to solve the issue. We'll expect to get more clarity by the end of our Wednesday (May 4, 2022). This blog post will be updated as soon as we have any update.
We sincerely apologize for the inconvenience.
