@@ -28,8 +28,8 @@ Released at 2024-05-28
 * FEATURE: add [`field_values` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#field_values-pipe), which returns unique values for the given [log field](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model).
 * FEATURE: allow omitting `stats` prefix in [`stats` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#stats-pipe). For example, `_time:5m | count() rows` is a valid query now. It is equivalent to `_time:5m | stats count() as rows`.
 * FEATURE: allow omitting `filter` prefix in [`filter` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#filter-pipe) if the filter doesn't clash with [pipe names](#https://docs.victoriametrics.com/victorialogs/logsql/#pipes). For example, `_time:5m | stats by (host) count() rows | rows:>1000` is a valid query now. It is equivalent to `_time:5m | stats by (host) count() rows | filter rows:>1000`.
-* FEATURE: allow [`head` pipe](https://docs.victoriametrics.com/victorialogs/logsql/#limit-pipe) without number. For example, `error | head`. In this case 10 last values are returned as `head` Unix command does by default.

For example, `some_text_field:>="foo"` matches [log entries](https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model) with `some_text_field` field values bigger or equal to `foo`.
