tip #

BUGFIX: Single-node VictoriaTraces and vtinsert in VictoriaTraces cluster : fix OTLP/gRPC failure with TLS enabled during HTTP/2 ALPN negotiation. See #108 for details. Thank @hklhai for the pull request #136 .

Released at 2026-04-14

SECURITY: upgrade Go builder from Go1.26.0 to Go1.26.2. See the list of issues addressed in Go1.26.1 and Go1.26.2 .
FEATURE: Single-node VictoriaTraces and vtstorage in VictoriaTraces cluster : allow generating service graph relation by database client span. The client span contains db.system.name attribute will generate a service.name:db.system.name (example: account_service:mysql) relation. It can be disabled by setting -servicegraph.databaseTaskLimit=0. Thank @wsx864321 for the pull request #117 .
FEATURE: dashboards/single-node , dashboards/cluster : add clickable source code links to the Logging rate panel in Overview. Users can use it to navigate directly to the source code location that generated those logs, making debugging and code exploration easier. See #106 .
FEATURE: Single-node VictoriaTraces and vtselect in VictoriaTraces cluster : support positive regex matching in the Jaeger query API when filtering traces by tags. See the pull request #116 for examples. Thank @emamihe for the pull request.

SECURITY: upgrade Go builder from Go1.25.5 to Go1.26.0. See the list of issues addressed in Go1.26.0 .
SECURITY: upgrade base docker image (Alpine) from 3.22.2 to 3.23.3. See Alpine 3.23.3 release notes .
BUGFIX: fix VictoriaTraces Docker OCI labels org.opencontainers.image.source and org.opencontainers.image.documentation: point them to VictoriaTraces repo/docs instead of VictoriaMetrics.
BUGFIX: All VictoriaTraces components: Fix unsupported metric type display in exposed metric metadata for summaries and quantiles. This unsupported type exists when a summary is not updated within a certain time window. See #120 for details.
FEATURE: Single-node VictoriaTraces and vtselect, vtstorage in VictoriaTraces cluster : (experimental) add support for Tempo datasource APIs . This starts with support for the basic auto-completion /tags, search /search, and /v2/traces/* APIs. TraceQL metrics and pipelines are not yet available in this release.
FEATURE: logstorage : upgrade VictoriaLogs dependency from v1.43.1 to v1.47.0 .

Released at 2026-01-24

FEATURE: Single-node VictoriaTraces and vtstorage in VictoriaTraces cluster : adjust -insert.indexFlushInterval from 30s to 20s to ensure a proper time gap with -search.latencyOffset. This is useful when ingest data is not real-time, as it helps reduce the probability that data can be searched by condition but is not present in the traceID index, resulting in failure to query by traceID.
BUGFIX: Single-node VictoriaTraces and vtselect in VictoriaTraces cluster : fix backward compatibility for the old index format. Previously, the old index format was not parsed correctly into the start and end timestamps.

Released at 2026-01-21

FEATURE: Single-node VictoriaTraces and VictoriaTraces cluster : add duration and error metrics for service graph background tasks. Thank @chenlujjj for the pull request #100 .
FEATURE: Single-node VictoriaTraces and VictoriaTraces cluster : add accurate start time and end time to the trace ID index. This should help with the trace lookup by ID, and will free user from configuring -search.traceMaxDurationWindow to avoid missing the spans. See the pull request #81 .

Released at 2026-01-07

SECURITY: upgrade Go builder from Go1.25.4 to Go1.25.5. See the list of issues addressed in Go1.25.5 .
FEATURE: logstorage : upgrade VictoriaLogs dependency from v1.38.0 to v1.43.1 .
FEATURE: Single-node VictoriaTraces and vtinsert in VictoriaTraces cluster : reduce CPU usage of the OpenTelemetry protobuf data ingestion in both OTLP/HTTP and OTLP/gRPC APIs. Thanks to @vadimalekseev for the initial idea .
