204
205## 0.17.0 / 2019-05-02
206
207This release includes changes to amtool which are not fully backwards
208compatible with the previous amtool version (#1798) related to backup and
209import of silences. If a backup of silences is created using a previous
210version of amtool (v0.16.1 or earlier), it is possible that not all silences
211can be correctly imported using a later version of amtool.
212
213Additionally, the groups endpoint that was dropped from api v1 has been added
214to api v2. The default for viewing alerts in the UI now consumes from this
215endpoint and displays alerts grouped according to the groups defined in the
216running configuration. Custom grouping is still supported.
217
218This release has added two new flags that may need to be tweaked. For people
219running with a lot of concurrent requests, consider increasing the value of
220`--web.get-concurrency`. An increase in 503 errors indicates that the request
221rate is exceeding the number of currently available workers. The other new
222flag, --web.timeout, limits the time a request is allowed to run. The default
223behavior is to not use a timeout.
224

245## 0.16.2 / 2019-04-03
246
247Updating to v0.16.2 is recommended for all users using the Slack, Pagerduty,
248Hipchat, Wechat, VictorOps and Pushover notifier, as connection errors could
249leak secrets embedded in the notifier's URL to stdout.
