Revision 228/229

_{Aug 13, 2024}

Dear community,

Canonical’s newest Charmed PgBouncer K8s operator has been published in the 1/stable channel

Due to its mult-architecture support, PgBouncer charm releases two revisions simultaneously:

• Revision 229 is built for amd64
• Revision 228 is built for for arm64

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

Otherwise, it can be done at deploy time with the --constraints flag:

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

where <arch> can be amd64 or arm64.

If you are jumping over several stable revisions, make sure to check previous release notes before upgrading to this revision.
