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 golang.org/x/sync from 0.20.0 to 0.21.0

Commits

Updates google.golang.org/grpc from 1.81.0 to 1.82.1

Release notes

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

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)
  • 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)
  • 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)

Bug Fixes

  • xds/server: Fix a memory leak of HTTP filter instances occurring when route configurations are updated in-place during a Route Discovery Service (RDS) update. (#9138)
  • grpc: In the deprecated gzip Compressor (used via the deprecated WithCompressor dial option), enforce the MaxRecvMsgSize limit on the decompressed message buffer, preventing excessive memory allocation from highly compressed payloads. (#9114)
  • stats/opentelemetry: Record retry attempts, grpc.previous-rpc-attempts, at the call level and not the attempt level. (#8923)
  • encoding: Ensure Close() is always called on readers returned from Compressor.Decompress if possible. (#9135)
  • channelz: Fix the LastMessageSentTimestamp and LastMessageReceivedTimestamp fields in SocketMetrics to ensure they contain correct timestamp values. (#9109)

Release 1.81.1

Security

  • xds/rbac: Fix a potential authorization bypass caused by incorrectly falling through URI/DNS SANs to Subject Distinguished Name (DN) when matching the authenticated principal name. With this fix, only the first non-empty identity source will be used, as per gRFC A41. (#9111)

Bug Fixes

  • otel: Segregate client and server RPC information used for metrics and traces, to avoid one overwriting the other. (#9081)

Updates github.com/redis/go-redis/v9 from 9.19.0 to 9.21.0

Release notes

Sourced from github.com/redis/go-redis/v9's releases.

9.21.0

This is a minor release adding new features and bug fixes. There are no breaking changes; upgrading from 9.20.x is a drop-in replacement.

🚀 Highlights

Zero-copy GetToBuffer / SetFromBuffer

Two new StringCmdable methods let callers read and write Redis string values directly into and from pre-allocated byte buffers, eliminating the per-call payload allocation that Get/Set incur:

GetToBuffer(ctx, key, buf) *ZeroCopyStringCmd   // reads into buf; ZeroCopyStringCmd { Val() int; Bytes() []byte; Result() (int, error) }
SetFromBuffer(ctx, key, buf) *StatusCmd

GetToBuffer decodes the bulk reply straight into the caller-owned buf (no intermediate allocation); a buffer that is too small returns an error after draining the payload, so the connection stays aligned for the next reply. SetFromBuffer is provided for API symmetry — it dispatches to the same []byte writer path as Set(ctx, key, buf, 0) and produces byte-identical output on the wire. Available on *Client, *ClusterClient, *Ring, *Conn and Pipeliner.

(#3834) by @​ndyakov

Explicit LIMIT 0 for stream trimming

Redis treats XTRIM/XADD approximate-trim (~) LIMIT 0 as "disable the trimming effort cap entirely", which differs from omitting LIMIT (the implicit 100 * stream-node-max-entries default). The command builders previously only emitted LIMIT when limit > 0, so callers could never send an explicit LIMIT 0. Following the KeepTTL = -1 precedent, the new XTrimLimitDisabled = -1 sentinel now emits an explicit LIMIT 0; limit == 0 keeps the historical no-LIMIT behavior, so existing callers produce byte-identical commands.

(#3848) by @​TheRealMal

✨ New Features

  • Zero-copy buffer string commands: new GetToBuffer / SetFromBuffer on StringCmdable and the ZeroCopyStringCmd result type, reading/writing string values into caller-owned buffers without per-call payload allocation (#3834) by @​ndyakov
  • XTrimLimitDisabled sentinel: XTRIM/XADD approximate trimming can now send an explicit LIMIT 0 to disable the trim effort cap, via the new XTrimLimitDisabled = -1 sentinel (#3848) by @​TheRealMal
  • PubSub health-check timeouts: channel.initHealthCheck now bounds the Ping it issues with a fresh per-check timeout context (the exported pingTimeout / reconnectTimeout) instead of context.TODO(), so a stuck health-check Ping can no longer block indefinitely (#3819) by @​abdellani
  • Skip redundant UNWATCH in Tx.Close: a transaction now tracks whether a WATCH is still active (watchArmed) and only issues UNWATCH on Close when it is, removing an extra round trip on the common WATCH/.../EXEC and no-key Watch paths while never returning a connection to the pool with an active watch (#3854) by @​fcostaoliveira

🐛 Bug Fixes

  • maintnotifications ModeAuto fail-open: ModeAuto now stays fail-open when the server does not support maintenance notifications — connections are retired and tracking is guarded during downgrade so the client keeps working instead of erroring (#3853) by @​terrorobe

9.20.1

This is a patch release containing bug fixes only. There are no new features or breaking changes; upgrading from 9.20.0 is a drop-in replacement.

🚀 Highlights

RESP3 pub/sub message loss fixed

PeekPushNotificationName previously inspected only the bytes already buffered by bufio, so when a push frame header straddled a buffer fill boundary it could return a truncated notification name (e.g. "messa" instead of "message"). The push processor then mis-routed the frame and ReadReply silently dropped it, causing intermittent RESP3 pub/sub message loss. The peek now grows its window (36 bytes → up to 4 KiB) and reads more from the connection until the header is complete, cleanly separating incomplete prefixes from corrupt frames (including overflow-safe bulk-length handling). Fixes #3839.
