| * [FEATURE] Query Frontend: Add dynamic interval size for query splitting. This is enabled by configuring experimental flags `querier.max-shards-per-query` and/or `querier.max-fetched-data-duration-per-query`. The split interval size is dynamically increased to maintain a number of shards and total duration fetched below the configured values. #6458 | ||
| * [FEATURE] Querier/Ruler: Add `query_partial_data` and `rules_partial_data` limits to allow queries/rules to be evaluated with data from a single zone, if other zones are not available. #6526 | ||
| * [FEATURE] Update prometheus alertmanager version to v0.28.0 and add new integration msteamsv2, jira, and rocketchat. #6590 | ||
| * [ENHANCEMENT] Alertmanager: Add new limits `-alertmanager.max-silences-count` and `-alertmanager.max-silences-size-bytes` for limiting silences per tenant. |

Is this the size for a single silence?
There was a problem hiding this comment.
The limit applies to each silence.
If one tenant has silences size of 100MB, 101MB, 102MB, and the limit is 200MB.
If a user adds a new silence with a size of 201MB, it fails.
