0.17.0 / 2019-05-02

This release includes changes to amtool which are not fully backwards compatible with the previous amtool version (#1798) related to backup and import of silences. If a backup of silences is created using a previous version of amtool (v0.16.1 or earlier), it is possible that not all silences can be correctly imported using a later version of amtool.

Additionally, the groups endpoint that was dropped from api v1 has been added to api v2. The default for viewing alerts in the UI now consumes from this endpoint and displays alerts grouped according to the groups defined in the running configuration. Custom grouping is still supported.

This release has added two new flags that may need to be tweaked. For people running with a lot of concurrent requests, consider increasing the value of --web.get-concurrency. An increase in 503 errors indicates that the request rate is exceeding the number of currently available workers. The other new flag, --web.timeout, limits the time a request is allowed to run. The default behavior is to not use a timeout.

0.16.2 / 2019-04-03

Updating to v0.16.2 is recommended for all users using the Slack, Pagerduty, Hipchat, Wechat, VictorOps and Pushover notifier, as connection errors could leak secrets embedded in the notifier's URL to stdout.

[BUGFIX] Redact notifier URL from logs to not leak secrets embedded in the URL (#1822, #1825)
[BUGFIX] Allow sending of unauthenticated SMTP requests when smtp_auth_username is not supplied (#1739)
