**v1.93.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes.
The v1.93.x line will be supported for at least 12 months since [v1.93.0](https://docs.victoriametrics.com/CHANGELOG.html#v1930) release**
* BUGFIX: [storage](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html): properly set next retention time for indexDB. Previously it may enter into endless retention loop. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4873) for details.
* BUGFIX: prevent from possible data loss during `indexdb` rotation. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4873) for details.
* BUGFIX: do not allow starting VictoriaMetrics components with improperly set boolean command-line flags in the form `-boolFlagName value`, since this leads to silent incomplete flags' parsing. This form should be replaced with `-boolFlagName=value`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4845).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly set labels from `-remoteWrite.label` command-line flag just before sending samples to the configured `-remoteWrite.url` according to [these docs](https://docs.victoriametrics.com/vmagent.html#adding-labels-to-metrics). Previously these labels were incorrectly set before [the relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling) configured via `-remoteWrite.urlRelabelConfigs` and [the stream aggregation](https://docs.victoriametrics.com/stream-aggregation.html) configured via `-remoteWrite.streamAggr.config`, so these labels could be lost or incorrectly transformed before sending the samples to remote storage. The fix allows using `-remoteWrite.label` for identifying `vmagent` instances in [cluster mode](https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4247) and [these docs](https://docs.victoriametrics.com/stream-aggregation.html#cluster-mode) for more details.
* BUGFIX: remove `DEBUG` logging when parsing `if` filters inside [relabeling rules](https://docs.victoriametrics.com/vmagent.html#relabeling-enhancements) and when parsing `match` filters inside [stream aggregation rules](https://docs.victoriametrics.com/stream-aggregation.html).
