v1.25.0

Compare Source

⚠️ This release raises the minimum required Go version to 1.26 and includes breaking API changes in api/prometheus/v1 (see the [CHANGE] entries below). ⚠️

1.25.0 / 2026-10-07

• [CHANGE] Minimum required Go version is now 1.26, only the two latest Go versions (1.26 and 1.27) are supported from now on. #​2138
• [CHANGE] api/prometheus/v1: Query, QueryRange, Series, LabelNames, and LabelValues now return Infos annotations in addition to Warnings, matching the Prometheus server's info annotations. This changes the signatures of these methods and of api.Client's Do/DoGetFallback; custom API client implementations must be updated. #​1963
• [CHANGE] api/prometheus/v1: Rework TSDBBlocks result types to align with the Prometheus server's tsdb.BlockMeta: TSDBBlocksResult now contains Blocks []TSDBBlockMeta directly instead of mirroring the full API envelope, nested types are renamed (TSDBBlockMeta, TSDBBlockStats, TSDBBlockMetaCompaction), stat fields are uint64 with omitempty tags, and the optional compaction parents field is included. #​1928
• [FEATURE] testutil: Add GatherAndFormat to encode a subset of metrics from a Gatherer. #​2091
• [FEATURE] promhttp: Add HandlerOpts.AcceptedFormats to customize the formats negotiated from the incoming Accept header, enabling opt-in to experimental formats such as OpenMetrics 2.0 without changing default negotiation. #​2146
• [ENHANCEMENT] promhttp: Negotiated metrics responses now include a Vary header. #​2142
• [ENHANCEMENT] prometheus: Regenerate the default runtime collector metrics for Go 1.25 and Go 1.26. #​2090, #​2095
• [ENHANCEMENT] testutil: Finalize OpenMetrics output in GatherAndFormat and CollectAndFormat (terminating # EOF). #​2125
• [BUGFIX] api: Match complete URL path placeholders only; a :foo argument no longer substitutes inside :foobar. #​2136
• [BUGFIX] exp/api/remote: Reset the pooled buffer before generic proto marshaling, preventing corrupted remote-write payloads. #​2139
• [BUGFIX] testutil/promlint: Fix "mibi" unit prefix to "mebi". #​2135
