13. Metrics usage tracker enabled by default, v1.122.0

14. Log new series toggle, v1.123.0
1.Call /internal/log_new_series?seconds=60 on vmstorage or vmsingle
2.Check the logs:
2025-10-02T08:40:38 info enabling logging of new series for the next 1m0s. This may increase resource usage during this period.
2025-10-02T08:40:39 info new series created:
vminsert_request_duration_seconds_bucket{job="victoria-metrics",instance="self",vmrange="1.136e-06...1.292e-06"}
2025-10-02T08:40:39 info new series created: vminsert_request_duration_seconds_sum{job="victoria-metrics",instance="self"}
2025-10-02T08:40:39 info new series created: vminsert_request_duration_seconds_count{job="victoria-metrics",instance="self"}
…
3. Logging disables automatically in `?seconds=<duration>`

15. Log new series toggle, v1.123.0

Thanks to @leiwingqueen!

16. Usability improvements
vmsingle and vmstorage in VictoriaMetrics cluster : The -snapshotsMaxAge flag default
have been changed to 3d.

This enables automatic deletion of snapshots older than 3 days.

If you want to keep the previous behavior (never automatically deleting snapshots), please set
-snapshotsMaxAge=0.

See #9344 for the details.

17. Usability improvements: share queries for debugging

18. Usability improvements: export raw data

19. Usability improvements: export raw data
●Export in Json or CSV format
●Raw data is essential for troubleshooting
●https://docs.victoriametrics.com/victoriametrics/troubl
eshooting/#unexpected-query-results
●Raw data can be easily imported into VM

20. Usability improvements: labels limit per target
vmagent and Single-node VictoriaMetrics : support label_limit scrape parameter.
It sets labels limit for each scraped sample from a target. If limit is exceeded, the scrape will be
rejected and target marked with corresponding scrape error.
The label_limit can be defined on global level, per job or during relabeling via
__label_limit__ label.
See #7660 and #3233 issues.

21. Performance optimizations
FEATURE: improve performance on systems with many CPU cores by removing the top sources of false sharing at global variables. See
#8682 . Thanks to @tIGO for raising this issue and for the initial attempt to fix it at the PR #8683 .
FEATURE: vmselect in VictoriaMetrics cluster : dynamically adjusts the concurrent dial limit between 8 and 64 based on
-search.maxConcurrentRequests . Additionally, goroutines now have the opportunity to access available connections while
awaiting the dial limit token. This enables faster connection establishment when sudden requests arrive and reduces the blocking time
during the availability check for connections. See #8922
FEATURE: vmsingle and vmstorage in VictoriaMetrics cluster : reduce CPU usage caused by garbage collection during indexDB
lookups on cache misses. See #9324 for details.
FEATURE: vmagent and vmsingle : improve Kubernetes service discovery performance with large amount of configured role selectors.
See this #9354 issue for details. Thanks to the @fxrlv
FEATURE: vmsingle and vmstorage in VictoriaMetrics cluster : optimize /api/v1/labels and /api/v1/label/TAG/values
requests with a single match or extra_filters filter containing time series metric name. See this PR #9489 for details.
