Dear users,

I have received a report in Alertmanager that the changes in the
matchers we have introduced in Alertmanager 0.22 might not work properly
with the API v1.

The API v1 might invert the silence and silent everything but what you
try to silent.

Therefore, it is recommended to use amtool 0.22 with alertmanager 0.22
and use the API v2 to create silences with alertmanager.

We are still investigating the situation, you can see the report here:
We hope to release a 0.22.1 soon to address this issue.
