Hi, on the final stages of testing/releasing a regression was found, thus 5.10.8will not be declared as stable, it is available in our nightly image container registry docker pull crate/crate:5.10.8 but please note that we do not recommend that you use it, this is for testing only.
I’m not too sure, maybe, one way to quickly test it is using the PG wire protocol (in port 5432), since the linked issue is from the (HTTP protocol, in port 4200.)
I would recommend that you open a new post with more information and context of your issue so we can better help you debug it.
