* FEATURE: add support of `lowercase` and `uppercase` relabeling actions in the same way as [Prometheus 2.36.0 does](https://github.com/prometheus/prometheus/releases/tag/v2.36.0). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2664).
* FEATURE: add ability to change the `indexdb` rotation timezone offset via `-retentionTimezoneOffset` command-line flag. Previously it was performed at 4am UTC time. This could lead to performance degradation in the middle of the day when VictoriaMetrics runs in time zones located too far from UTC. Thanks to @cnych for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2574).
* FEATURE: limit the number of background merge threads on systems with big number of CPU cores by default. This increases the max size of parts, which can be created during background merge when `-storageDataPath` directory has limited free disk space. This may improve on-disk data compression efficiency and query performance. The limits can be tuned if needed with `-smallMergeConcurrency` and `-bigMergeConcurrency` command-line flags. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2673).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): support `limit` param per-group for limiting number of produced samples per each rule. Thanks to @Howie59 for [implementation](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2676).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): remove dependency on Internet access at [web API pages](https://docs.victoriametrics.com/vmalert.html#web). Previously the functionality and the layout of these pages was broken without Internet access. See [shis issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2594).
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): implement the `http://vmagent:8429/service-discovery` page in the same way as Prometheus does. This page shows the original labels for all the discovered targets alongside the resulting labels after the relabeling. This simplifies service discovery debugging.
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): remove dependency on Internet access at `http://vmagent:8429/targets` page. Previously the page layout was broken without Internet access. See [shis issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2594).

* Graphite engine isn't supported yet;
* `query` template function is disabled for performance reasons (might be changed in future);
* `limit` group's param has no effect during replay (might be changed in future);
