v1.7.2: rename notices "select" to "users", avoid acquiring state lock in /v1/health
This patch release adds the following changes since v1.7.1:
- #368: replace "select=all" with "users=all". Strictly speaking this is a breaking change, however, it was a design mistake and we want to fix it as soon as possible. It's almost certainly that no one is using this feature yet.
- #369: avoid acquiring state lock in health check endpoint. This fixes (or is one aspect of the fix for) the issue described in https://bugs.launchpad.net/juju/+bug/2052517, so that the
GET /v1/health
endpoint returns much quicker even when under load.
