* FEATURE: [syslog data ingestion](https://docs.victoriametrics.com/victorialogs/data-ingestion/syslog/): allow adding arbitrary [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) via `[label1=value1 ... labelN=valueN]` syntax inside Syslog messages. For example, `<165>1 2024-06-03T17:42:00.000Z example.com appname 12345 ID47 [field1=value1 field2=value2] some message`.
* FEATURE: [syslog data ingestion](https://docs.victoriametrics.com/victorialogs/data-ingestion/syslog/): allow dropping the specified [log fields](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) during data ingestion.

* BUGFIX: [HTTP querying APIs](https://docs.victoriametrics.com/victorialogs/querying/#http-api): properly take into account the `end` query arg when calculating time range for [`_time:duration` filter](https://docs.victoriametrics.com/victorialogs/logsql/#time-filter). Previously the `_time:duration` filter was treated as `_time:[now-duration, now)`, while it should be treated as `_time:[end-duration, end)`.
