@ -15,6 +15,7 @@ The following `tip` changes can be tested by building VictoriaMetrics components
* BUGFIX: [vmalert](https://docs.victoriametrics.com/vmalert.html): strip sensitive information such as auth headers or passwords from datasource, remote-read, remote-write or notifier URLs in log messages or UI. This behavior is by default and is controlled via `-datasource.showURL`, `-remoteRead.showURL`, `remoteWrite.showURL` or `-notifier.showURL` cmd-line flags. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5044).
* BUGFIX: [vmselect](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): improve performance and memory usage during query processing on machines with big number of CPU cores. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5087) for details.
* BUGFIX: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): bump hard-coded limit for search query size at `vmstorage` from 1MB to 5MB. The change should be more suitable for real-world scenarios and protect vmstorage from excessive memory usage. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5154) for details
* BUGFIX: [vmbackup](https://docs.victoriametrics.com/vmbackup.html): properly copy `appliedRetention.txt` files inside `<-storageDataPath>/{data}` folders during [incremental backups](https://docs.victoriametrics.com/vmbackup.html#incremental-backups). Previously the new `appliedRetention.txt` could be skipped during incremental backups, which could lead to increased load on storage after restoring from backup. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5005).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): suppress `context canceled` error messages in logs when `vmagent` is reloading service discovery config. This error could appear starting from [v1.93.5](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.93.5). See [this PR](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5048).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): allow passing [median_over_time](https://docs.victoriametrics.com/MetricsQL.html#median_over_time) to [aggr_over_time](https://docs.victoriametrics.com/MetricsQL.html#aggr_over_time). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5034).
