Revision 180/181

_{September 2, 2024}

Dear community,

Canonical’s newest Charmed MySQL K8s operator has been published in the 8.0/stable channel.

Due to the newly added support for arm64 architecture, the MySQL K8s charm now releases two revisions simultaneously:

• Revision 180 is built for amd64
• Revision 181 is built for arm64

TO make sure you deploy for the right architecture, we recommend setting an architecture constraint for your entire Juju model.

Otherwise, you can specify the architecture at deploy time with the --constraints flag as follows:

juju deploy mysql-k8s --constraints arch=<arch> --trust

where <arch> can be amd64 or arm64.
