Released at 2024-11-08
* FEATURE: [`join` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#join-pipe): add an ability to add prefix to all the log field names from the joined query, by using `| join by (<by_fields>) (<query>) prefix "some_prefix"` syntax. * FEATURE: [`join` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#join-pipe): add an ability to add prefix to all the log field names from the joined query, by using `| join by (<by_fields>) (<query>) prefix "some_prefix"` syntax.
* FEATURE: [`_time` filter](https://docs.victoriametrics.com/victorialogs/logsql/#time-filter): allow specifying offset without time range. For example, `_time:offset 1d` matches all the logs until `now-1d` in the [`_time` field](https://docs.victoriametrics.com/victorialogs/keyconcepts/#time-field). This is useful when building graphs for time ranges with some offset in the past. * FEATURE: [`_time` filter](https://docs.victoriametrics.com/victorialogs/logsql/#time-filter): allow specifying offset without time range.

* FEATURE: [`/select/logsql/tail` HTTP endpoint](): support for `offset` query arg, which can be used for delayed emission of matching logs during live tailing.
