This patch release brings a fix for Receive, for a bug that allowed the head series limiter to be run without explicitly setting it. It also brings a fix for Store GW, for a bug that caused /api/v1/labels to not filter external labels.

Alongside this, we also build with Go 1.21.3 and golang.org/x/net v0.17 in this release to address Go CVE.
Please try it out and let us know if you spot any problems! Enjoy! 🎉
