New Release

Cloudberry Database v1.5.3 was released with a few improvements, bug fixes, and doc updates. You can check the release notes for details.

Our Bootcamp program has supported Cloudberry Database v1.5.2 in #422, but we will not support v1.5.3 because extra dependencies are needed in this release. We will update the bootcamp until the next release v1.5.4 this June.


In the past weekends, Cloudberry Database was on the "GitHub trending/C" list for two days. And our stars grew a lot, thanks to all the stargazers:
