* FEATURE: dashboards: use `version` instead of `short_version` in version change annotation for single/cluster dashboards. The update should reflect version changes even if different flavours of the same release were applied (custom builds). * FEATURE: dashboards: use `version` instead of `short_version` in version change annotation for single/cluster dashboards. The update should reflect version changes even if different flavours of the same release were applied (custom builds).
* FEATURE: lower limit for `import.maxLineLen` cmd-line flag from 100MB to 10MB in order to prevent excessive memory usage during data import. Please note, the line length of exported data can be limited with `max_rows_per_line` query arg passed to `/api/v1/export`. The change affects vminsert/vmagent/VictoriaMetrics single-node.
* BUGFIX: fix a bug, which could result in improper results and/or to `cannot merge series: duplicate series found` error during [range query](https://docs.victoriametrics.com/keyConcepts.html#range-query) execution. The issue has been introduced in [v1.95.0](https://docs.victoriametrics.com/CHANGELOG.html#v1950). See [this bugreport](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5332) for details. * BUGFIX: fix a bug, which could result in improper results and/or to `cannot merge series: duplicate series found` error during [range query](https://docs.victoriametrics.com/keyConcepts.html#range-query) execution.

* BUGFIX: improve deadline detection when using buffered connection for communication between cluster components. Before, due to nature of a buffered connection the deadline could have been exceeded while reading or writing buffered data to connection.
