Full Changelog: prometheus/client_golang@v1.24.0...v1.24.1

v1.24.0 - 2026-07-20

Changes

• [CHANGE] Minimum required Go version is now 1.25, only the two latest Go versions (1.25 and 1.26) are supported from now on. #1862
• [CHANGE] prometheus: Name validation now always uses the UTF-8 scheme instead of the deprecated model.NameValidationScheme global. Default behavior is unchanged; code that set NameValidationScheme = LegacyValidation no longer gets legacy enforcement at metric, label, and push-grouping construction. #2051
• [CHANGE] api/prometheus/v1: Support matchers (matches[] parameter) in Rules method (Rules(ctx context.Context, matches []string) (RulesResult, error)). #1843
• [CHANGE] api/prometheus/v1: Refactor LabelNames method to return model.LabelNames instead of []string for consistency across the API. #1850
• [CHANGE] exp/api/remote: Simplify Store interface, rename Handler to WriteHandler, and encapsulate write response handling. #1855
• [FEATURE] prometheus: Add new Go 1.26 runtime metrics (/sched/goroutines-created:goroutines, /sched/goroutines/not-in-go:goroutines, /sched/goroutines/runnable:goroutines, /sched/goroutines/running:goroutines, /sched/goroutines/waiting:goroutines, /sched/threads/total:threads). #1942
• [FEATURE] prometheus: Add WithUnit(unit string) option and explicit OpenMetrics unit support in CounterOpts, GaugeOpts, SummaryOpts, and HistogramOpts. #1392
• [FEATURE] prometheus: Expose descriptor construction error through public Err() method on Desc. #1902
• [FEATURE] promhttp: Add opt-in HandlerOpts.CoalesceGather to deduplicate concurrent Gather calls so overlapping scrapes share one collection cycle, preventing goroutine pile-up when the scrape rate outpaces collection time. #1969
• [FEATURE] promhttp: HTTP handlers created by promhttp package now support metrics filtering by providing one or more name[] query parameters. The default behavior when none are provided remains the same, returning all metrics. #1925
• [FEATURE] api/prometheus/v1: Add query formatting endpoint support (/format_query) and FormatQuery(ctx context.Context, query string) (string, error) method. #1846, #1856
• [FEATURE] api/prometheus/v1: Add support for /status/tsdb/blocks endpoint via TSDBBlocks(ctx context.Context) ([]TSDBBlock, error) method. #1896
• [FEATURE] exp/api/remote: Export BackoffConfig to allow customization when using WithAPIBackoff. #1895
• [FEATURE] exp/api/remote: Add RetryCallBack to allow custom logging or handling on retry attempts in the remote write client. #1888, #1890
• [ENHANCEMENT] prometheus/collectors/version: Allow specifying custom labels when registering the version collector. #1860
• [ENHANCEMENT] api: Use cloned http.DefaultTransport when constructing default HTTP clients to prevent accidental mutations of shared global transport state. #1885
• [BUGFIX] prometheus: Recover from collector panics during Gather() and return an error instead of crashing the process. #1961
• [BUGFIX] prometheus: Fix cpu-seconds unit suffix handling for metric go_cpu_classes_gc_mark_assist_cpu_seconds. #1991
• [BUGFIX] promhttp: InstrumentHandlerDuration and InstrumentHandlerCounter no longer panic when given an observer/counter that does not implement ExemplarObserver/ExemplarAdder (e.g. a SummaryVec). The exemplar is dropped and the value is recorded via the plain Observe/Add path, matching the safe-cast already used by Timer.ObserveDurationWithExemplar. #2005
• [BUGFIX] api/prometheus/v1: Fall back to GET requests when POST requests return 403 Forbidden or method not allowed. #2030
• [BUGFIX] api: Respect context cancellation inside httpClient.Do. #1971
• [BUGFIX] exp/api/remote: Fix compression buffer pooling where compressed buffers were released prematurely, causing corrupted remote-write payloads. #1889
• [BUGFIX] exp/api/remote: Reject malformed snappy payloads declaring huge decoded sizes. Enforce a 32MB decoded-size limit to prevent OOM from oversized remote-write requests. #1917
• [BUGFIX] exp/api/remote: Ensure remote write v2 headers cannot be returned on v1 requests. #1927

Updates google.golang.org/grpc from 1.81.1 to 1.83.0

Release notes

Sourced from google.golang.org/grpc's releases.

Release 1.83.0

Security

• server: Stop reading from connections when flooded by HTTP/2 frames to mitigate resource exhaustion. The default value for this limit is 100 frames, excluding DATA and HEADERS, and may be changed by setting environment variable GRPC_GO_EXPERIMENTAL_CONTROL_BUFFER_THROTTLE_LIMIT.
• xds/rbac: Support Metadata and RequestedServerName permissions matcher fields. If present in a DENY rule, previously these would be ignored and fail-open.
• xds/rbac: Fix panic when parsing unsupported fields in NotRule/NotId permissions.
• xds/rbac: Support the deprecated source_ip principal identifier by treating it as equivalent to direct_remote_ip.
• xds: Fix panic when parsing route header matchers configured with empty exact_match, prefix_match, or suffix_match strings. (#9223)

New Features

• xds/googlec2p: Enable DirectPath over Interconnect support for on-premises clients via the force-xds target URI query parameter. (#9133)
• xds: Enable xDS configuration to control which fields get propagated from ORCA backend metric reports to LRS load reports. (#9145)
• authz: Add OnPolicyUpdate callback to FileWatcherOptions to notify when an authz policy is loaded or updated. (#9142)
  • Special Thanks: @​hnefatl
• xds: Add support for the GCP Authentication HTTP Filter, which automatically fetches and attaches GCP Service Account Identity JWT tokens to outgoing RPCs.
  • This feature can be enabled by setting environment variable GRPC_EXPERIMENTAL_XDS_GCP_AUTHENTICATION_FILTER=true. (#9119)
• xds: Add support for xDS-based HTTP CONNECT proxies.
  • This feature can be enabled by setting environment variable GRPC_EXPERIMENTAL_XDS_HTTP_CONNECT=true. (#9151)
• xds: Add support for contains_match in route header matchers. (#9223)

Bug Fixes

• credentials/alts: Fix panic when processing malformed frames by validating that the message frame length exceeds the message type field size. (#9197)
• grpc: Fix compilation on Plan 9 targets (GOOS=plan9), broken since v1.81.0. (#9255)
  • Special Thanks: @​Yusufihsangorgel

Release 1.82.1

Security

• server: Stop reading from the connection when flooded by HTTP/2 frames. The default value for this limit is 100 frames, excluding DATA and HEADERS, and may be changed by setting environment variable GRPC_GO_EXPERIMENTAL_CONTROL_BUFFER_THROTTLE_LIMIT.
• xds/rbac: Support Metadata and RequestedServerName permissions matcher fields. If present in a DENY rule, previously these would be ignored and fail-open.
• xds/rbac: Fix panic when parsing unsupported fields in NotRule/NotId permissions.
• xds/rbac: Support the deprecated source_ip principal identifier by treating it as equivalent to direct_remote_ip.

Release 1.82.0

Behavior Changes

• server: Remove support for GRPC_GO_EXPERIMENTAL_DISABLE_STRICT_PATH_CHECKING environment varibale. Strict incoming RPC path validation (which has been the default since v1.79.3) can no longer be disabled. (#9112)
• transport: Add environment variable to change the default max header list size from 16MB to 8KB. This may be enabled by setting GRPC_GO_EXPERIMENTAL_ENABLE_8KB_DEFAULT_HEADER_LIST_SIZE=true. This will be enabled by default in a subsequent release. (#9019)
• balancer: Load Balancing policy registry is now case-sensitive. Set GRPC_GO_EXPERIMENTAL_CASE_SENSITIVE_BALANCER_REGISTRIES=false (and file an issue) to revert to case-insensitive behavior. (#9017)

New Features

• experimental/stats: Expose a new API, NewContextWithLabelCallback, to register a callback that is invoked when telemetry labels are added. (#8877)
  • Special Thanks: @​seth-epps
• client: Return a portion of the response body in the error message, when the client receives an unexpected non-gRPC HTTP response, to make debugging easier. (#8929)
  • Special Thanks: @​chengxilo
• server: Add environment variable GRPC_GO_SERVER_GOROUTINE_LABELS that controls setting runtime/pprof.Labels on goroutines spawned by the server. Set GRPC_GO_SERVER_GOROUTINE_LABELS=grpc.method=true to add the grpc.method label on goroutines spawned to handle incoming requests. (#9082)

v0.29.3

Minimum supported Tailscale client version: v1.80.0

Changes

• Fix tagged node stuck expired after tailscale logout, unable to re-authenticate #3394
• Re-registering a tagged node with a different pre-auth key now applies the new key's tags instead of silently keeping the old ones #3394
• Fix re-authenticating an already-tagged node with --advertise-tags being rejected when the authenticating user owns the tags #3394
• Fix ephemeral nodes lingering as disconnected after reconnect churn #3383
• Fix node registration falsely returning 401 registration timed out when auth completes as the request context expires #3392
• Check the machine key on the followup registration poll so a leaked auth ID cannot return the registering user's identity #3393
• Reject /key requests below the supported capability version floor, matching /ts2021 #3391

Upgrade

Please follow the steps outlined in the upgrade guide to update your existing Headscale installation.

Minimum supported Tailscale client version: v1.80.0

Changes

• Fix nodes with tags='null' losing their assigned user on upgrade #3325

0.29.0 (2026-06-17)

Minimum supported Tailscale client version: v1.80.0

Tailscale ACL compatibility improvements

Extensive test cases were systematically generated using Tailscale clients and the official SaaS to understand how the packet filter should be generated. We discovered a few differences, but overall our implementation was very close. #3036

SSH check action

SSH rules with "action": "check" are now supported. When a client initiates a SSH connection to a node with a check action policy, the user is prompted to authenticate via OIDC or CLI approval before access is granted. OIDC approval requires the authenticated user to own the source node; tagged source nodes cannot use SSH check-mode.
