Telegraf v1.39.1 released on 29-06-2026

Telegraf v1.39.1 is out now. It delivers a set of bugfixes across inputs and processors, adds configuration migrations to ease upgrades, and updates numerous dependencies for improved stability.
See the project’s GitHub release page for full details, downloads and SHA256 checksums for the published binaries and packages.
What’s in this release
- Bugfixes for multiple inputs and processors — examples include correct tarball creation, inputs.opcua session handling and client-cert behaviour, removal of deprecated openweathermap v2.5 group API calls, smartctl parsing of stdout only, tail panic prevention under load, non-blocking hwmon reads for temp, and restoration of the vSAN overall_health metric in inputs.vsphere; processors.parser now handles metrics without inner timestamps correctly.
- Configuration migrations added for several plugins to automate option/key transitions: inputs.aerospike, inputs.kafka_consumer (connection_strategy), inputs.openstack (server_diagnostics), inputs.openweathermap (query_style), inputs.tail (from_beginning) and outputs.amon.
- Dependency bumps across many libraries (examples include github.com/gopcua/opcua, Azure SDK packages, IBM sarama, aws-sdk-go-v2 group, OpenTelemetry pdata and various golang.org/x/* modules) and published binary packages for many platforms with SHA256 checksums.
Upgrade notes
- Run the included migrations when upgrading and back up your existing configuration first; the listed migrations will move options for the noted inputs/outputs to preserve behaviour where possible.
- If you pin transitive dependencies or run custom builds, test the upgrade in a staging environment and verify the downloaded package checksums before installation; if required, revert to your prior known-good installer and configuration.
Share your experience after upgrading or report any problems on the project’s GitHub so others can benefit from your findings.
