### Changed

- ⚠️ **Breaking Change:** `go.opentelemetry.io/otel/sdk/metric` now
applies a default cardinality limit of 2000 to comply with the Metrics
SDK specification recommendation.
New attribute sets are dropped when the cardinality limit is reached.
The measurement of these sets are aggregated into a special attribute
set containing `attribute.Bool("otel.metric.overflow", true)`.
  This can break users who relied on the previous unlimited default.
Set `WithCardinalityLimit(0)` or the deprecated
`OTEL_GO_X_CARDINALITY_LIMIT=0` environment variable to preserve
unlimited cardinality.
Note that support for `OTEL_GO_X_CARDINALITY_LIMIT` may be removed in a
future release. (#8247)
- `ErrorType` in `go.opentelemetry.io/otel/semconv` now unwraps errors
created with `fmt.Errorf` when deriving the `error.type` attribute.
(#8133)
- `go.opentelemetry.io/otel/sdk/log` now unwraps error chains created
with `fmt.Errorf` when deriving the `error.type` attribute from errors
on log records. (#8133)
- `Set.MarshalLog` method in `go.opentelemetry.io/otel/attribute` now
uses `Value.String` formatting following the [OpenTelemetry AnyValue
representation for non-OTLP
protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue).
(#8169)
- Optimize `go.opentelemetry.io/otel/sdk/metric` to return a drop
reservoir and short-circuit `Offer` calls to the exemplar reservoir when
`exemplar.AlwaysOffFilter` is configured. (#8211) (#8267)
- Optimize `go.opentelemetry.io/otel/sdk/metric` to return a drop
reservoir for asynchronous instruments when `exemplar.TraceBasedFilter`
is configured. (#8286)

### Deprecated

- Deprecate `Value.Emit` method in `go.opentelemetry.io/otel/attribute`.
  Use `Value.String` instead. (#8176)

### Fixed

- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Fix gzipped request body replay on redirect in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#8135)
- Fix gzipped request body replay on redirect in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8152)
- `go.opentelemetry.io/otel/exporters/prometheus` now uses
`Value.String` formatting for label values following the [OpenTelemetry
AnyValue representation for non-OTLP
protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue).
(#8170)
- Propagate errors from the exporter when calling `Shutdown` on
`BatchSpanProcessor` in `go.opentelemetry.io/otel/sdk/trace`. (#8197)
- Fix stale status code reporting on self-observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8226)
- Fix a concurrent `Collect` data race and potential panic in
`go.opentelemetry.io/otel/exporters/prometheus` when
`WithResourceAsConstantLabels` option is used. (#8227)
- Fix race condition in `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar` by reverting #7447.
(#8249)
- Fix `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar` to safely handle zero
size.
A capacity check in the constructor initializes the reservoir safely and
skips initialization for zero-cap; early returns in `Offer()` and
`Collect()` ensure no-op behavior. (#8295)
- Fix counting of spans and logs in self-observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`,
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`,
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`, and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8254)
- Drop conflicting scope attributes named `name`, `version`, or
`schema_url` from metric labels in
`go.opentelemetry.io/otel/exporters/prometheus`, preserving the
dedicated `otel_scope_name`, `otel_scope_version`, and
`otel_scope_schema_url` labels. (#8264)
- Close schema files opened by `ParseFile` in
`go.opentelemetry.io/otel/schema/v1.0` and
`go.opentelemetry.io/otel/schema/v1.1`.
([GHSA-995v-fvrw-c78m](https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-995v-fvrw-c78m))
- Enforce the 8192-byte baggage size limit during extraction/parsing,
changing behavior when the limit is exceeded in
`go.opentelemetry.io/otel/baggage` and
`go.opentelemetry.io/otel/propagation`. (#8222)
- Fix `go.opentelemetry.io/otel/semconv/v1.41.0` to include `Attr*`
helper methods for required attributes on observable instruments.
(#8361)
- Limit baggage extraction error reporting in
`go.opentelemetry.io/otel/propagation` to prevent malformed or oversized
baggage headers from flooding logs.

### Release Notes

<details>
<summary>mvdan/gofumpt (mvdan.cc/gofumpt)</summary>

###
[`v0.10.0`](https://redirect.github.com/mvdan/gofumpt/blob/HEAD/CHANGELOG.md#v0100---2026-05-04)

[Compare
Source](https://redirect.github.com/mvdan/gofumpt/compare/v0.9.2...v0.10.0)

This release is based on Go 1.26's gofmt, and requires Go 1.25 or later.

A new rule is introduced to drop unnecessary parentheses around
expressions
where the inner expression is unambiguous on its own, such as `f((3))`.
Parentheses are kept where they are useful, such as on binary
expressions. See
[#&#8203;44](https://redirect.github.com/mvdan/gofumpt/issues/44).

A new rule is introduced to require multi-line function calls to match
the opening and closing parenthesis in terms of the use of newlines. See
[#&#8203;74](https://redirect.github.com/mvdan/gofumpt/issues/74).

The `-extra` flag now accepts a comma-separated list of rule names to
enable
individual extra rules, rather than enabling all of them at once. See
[#&#8203;339](https://redirect.github.com/mvdan/gofumpt/issues/339).

The following changes are included as well:

- Avoid crashing on `go.mod` files without a `module` directive -
[#&#8203;350](https://redirect.github.com/mvdan/gofumpt/issues/350)
- Avoid failing when an ignored directory cannot be read -

### Release Notes

<details>
<summary>grpc/grpc-go (google.golang.org/grpc)</summary>

###
[`v1.81.0`](https://redirect.github.com/grpc/grpc-go/releases/tag/v1.81.0):
Release 1.81.0

[Compare
Source](https://redirect.github.com/grpc/grpc-go/compare/v1.80.0...v1.81.0)

### Behavior Changes

- balancer/rls: Switch gauge metrics to asynchronous emission (once per
collection cycle) to reduce telemetry noise and align with other gRPC
language implementations.
([#&#8203;8808](https://redirect.github.com/grpc/grpc-go/issues/8808))

### Dependencies

- Minimum supported Go version is now 1.25.
([#&#8203;8969](https://redirect.github.com/grpc/grpc-go/issues/8969))

### Bug Fixes

- xds: Use the leaf cluster's security config for the TLS handshake
instead of the aggregate cluster's config.
([#&#8203;8956](https://redirect.github.com/grpc/grpc-go/issues/8956))
- transport: Send a `RST_STREAM` when receiving an `END_STREAM` when the
stream is not already half-closed.
([#&#8203;8832](https://redirect.github.com/grpc/grpc-go/issues/8832))
- xds: Fix ADS resource name validation to prevent a panic.
([#&#8203;8970](https://redirect.github.com/grpc/grpc-go/issues/8970))

### New Features

- grpc/stats: Add support for custom labels in per-call metrics ([gRFC
A108](https://redirect.github.com/grpc/proposal/blob/master/A108-otel-custom-per-call-label.md)).
([#&#8203;9008](https://redirect.github.com/grpc/grpc-go/issues/9008))
- xds: Add support for Server Name Indication (SNI) and SAN validation
([gRFC
A101](https://redirect.github.com/grpc/proposal/blob/master/A101-SNI-setting-and-SNI-SAN-validation.md)).
Disabled by default. To enable, set `GRPC_EXPERIMENTAL_XDS_SNI=true`
environment variable.
([#&#8203;9016](https://redirect.github.com/grpc/grpc-go/issues/9016))
- xds: Add support to control which fields get propagated from ORCA
backend metric reports to LRS load reports ([gRFC
A85](https://redirect.github.com/grpc/proposal/blob/master/A85-lrs-custom-metrics-changes.md)).
Disabled by default. To enable, set
`GRPC_EXPERIMENTAL_XDS_ORCA_LRS_PROPAGATION=true`.
([#&#8203;9005](https://redirect.github.com/grpc/grpc-go/issues/9005))
- xds: Add metrics to track xDS client connectivity and cached resource
state ([gRFC
A78](https://redirect.github.com/grpc/proposal/blob/master/A78-grpc-metrics-wrr-pf-xds.md)).
([#&#8203;8807](https://redirect.github.com/grpc/grpc-go/issues/8807))
- stats/otel: Enhance `grpc.subchannel.disconnections` metric by adding
disconnection reason to the `grpc.disconnect_error` label ([gRFC
A94](https://redirect.github.com/grpc/proposal/blob/master/A94-subchannel-otel-metrics.md)).
This provides granular insights into why subchannels are closing.
([#&#8203;8973](https://redirect.github.com/grpc/grpc-go/issues/8973))
- mem: Add `mem.Buffer.Slice()` API to slice the buffer like a slice.
([#&#8203;8977](https://redirect.github.com/grpc/grpc-go/issues/8977))
  - Special Thanks: [@&#8203;ash2k](https://redirect.github.com/ash2k)

### Performance Improvements

- alts: Pool read buffers to lower memory utilization when sockets are
unreadable.
([#&#8203;8964](https://redirect.github.com/grpc/grpc-go/issues/8964))
- transport: Pool HTTP/2 framer read buffers to reduce idle memory
consumption. Currently limited to Linux for ALTS and non-encrypted
transports (TCP, Unix). To disable, set
`GRPC_GO_EXPERIMENTAL_HTTP_FRAMER_READ_BUFFER_POOLING=false` and report
any issues.

David Ashpole d96b420138 Add support for the development attributes advisory parameter (#8135) 
From [the
spec](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/api.md#instrument-advisory-parameter-attributes):

> ##### Instrument advisory parameter: `Attributes`

> **Status**: [Development](../document-status.md)

> Applies to all instrument types.

> `Attributes` (a list of [attribute
keys](../common/README.md#attribute)) is
the recommended set of attribute keys to be used for the resulting
metrics.

We already have `WithAttributes` options, so i've opted to name this
`WithDefaultAttributes` to avoid naming collisions. We could also
consider `WithAttributeKeys`, or `WithDefaultAttributeKeys`

Follows the pattern for experimental options introduced in
https://github.com/open-telemetry/opentelemetry-go/pull/8111

Damien Mathieu 9276201a64 Release v1.43.0 / v0.65.0 / v0.19.0 (#8128) 
Release issue:
https://github.com/open-telemetry/opentelemetry-go/issues/8127

## Added

- Add `IsRandom` and `WithRandom` on `TraceFlags`, and `IsRandom` on
`SpanContext` in `go.opentelemetry.io/otel/trace`
for [W3C Trace Context Level 2 Random Trace ID
Flag](https://www.w3.org/TR/trace-context-2/#random-trace-id-flag)
support. (#8012)
- Add service detection with `WithService` in
`go.opentelemetry.io/otel/sdk/resource`. (#7642)
- Add `DefaultWithContext` and `EnvironmentWithContext` in
`go.opentelemetry.io/otel/sdk/resource` to support plumbing
`context.Context` through default and environment detectors. (#8051)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.
(#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8038)
- Support attributes with empty value (`attribute.EMPTY`) in
`go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest`. (#8038)
- Add support for per-series start time tracking for cumulative metrics
in `go.opentelemetry.io/otel/sdk/metric`.
  Set `OTEL_GO_X_PER_SERIES_START_TIMESTAMPS=true` to enable. (#8060)
- Add `WithCardinalityLimitSelector` for metric reader for configuring
cardinality limits specific to the instrument kind. (#7855)

## Changed

- Introduce the `EMPTY` Type in `go.opentelemetry.io/otel/attribute` to
reflect that an empty value is now a valid value, with `INVALID`
remaining as a deprecated alias of `EMPTY`. (#8038)
- Refactor slice handling in `go.opentelemetry.io/otel/attribute` to
optimize short slice values with fixed-size fast paths. (#8039)
- Improve performance of span metric recording in
`go.opentelemetry.io/otel/sdk/trace` by returning early if
self-observability is not enabled. (#8067)
- Improve formatting of metric data diffs in
`go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest`. (#8073)

## Deprecated

- Deprecate `INVALID` in `go.opentelemetry.io/otel/attribute`. Use
`EMPTY` instead. (#8038)

## Fixed

- Return spec-compliant `TraceIdRatioBased` description. This is a
breaking behavioral change, but it is necessary to
make the implementation
[spec-compliant](https://opentelemetry.io/docs/specs/otel/trace/sdk/#traceidratiobased).
(#8027)
- Fix a race condition in `go.opentelemetry.io/otel/sdk/metric` where
the lastvalue aggregation could collect the value 0 even when no
zero-value measurements were recorded. (#8056)
- Limit HTTP response body to 4 MiB in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` to
mitigate excessive memory usage caused by a misconfigured or malicious
server.
Responses exceeding the limit are treated as non-retryable errors.
(#8108)
- Limit HTTP response body to 4 MiB in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` to
mitigate excessive memory usage caused by a misconfigured or malicious
server.
Responses exceeding the limit are treated as non-retryable errors.
(#8108)
- Limit HTTP response body to 4 MiB in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` to
mitigate excessive memory usage caused by a misconfigured or malicious
server.
Responses exceeding the limit are treated as non-retryable errors.
(#8108)
- `WithHostID` detector in `go.opentelemetry.io/otel/sdk/resource` to
use full path for `kenv` command on BSD. (#8113)
- Fix missing `request.GetBody` in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` to
correctly handle HTTP2 GOAWAY frame. (#8096)

### Release Notes

<details>
<summary>grpc/grpc-go (google.golang.org/grpc)</summary>

###
[`v1.80.0`](https://redirect.github.com/grpc/grpc-go/releases/tag/v1.80.0):
Release 1.80.0

[Compare
Source](https://redirect.github.com/grpc/grpc-go/compare/v1.79.3...v1.80.0)

### Behavior Changes

- balancer: log a warning if a balancer is registered with uppercase
letters, as balancer names should be lowercase. In a future release,
balancer names will be treated as case-insensitive; see
[#&#8203;5288](https://redirect.github.com/grpc/grpc-go/issues/5288) for
details.
([#&#8203;8837](https://redirect.github.com/grpc/grpc-go/issues/8837))
- xds: update resource error handling and re-resolution logic
([#&#8203;8907](https://redirect.github.com/grpc/grpc-go/issues/8907))
- Re-resolve all `LOGICAL_DNS` clusters simultaneously when
re-resolution is requested.
- Fail all in-flight RPCs immediately upon receipt of listener or route
resource errors, instead of allowing them to complete.

### Bug Fixes

- xds: support the LB policy configured in `LOGICAL_DNS` cluster
resources instead of defaulting to `pick_first`.
([#&#8203;8733](https://redirect.github.com/grpc/grpc-go/issues/8733))
- credentials/tls: perform per-RPC authority validation against the leaf
certificate instead of the entire peer certificate chain.
([#&#8203;8831](https://redirect.github.com/grpc/grpc-go/issues/8831))
- xds: enabling A76 ring hash endpoint keys no longer causes EDS
resources with invalid proxy metadata to be NACKed when HTTP CONNECT
(gRFC A86) is disabled.
([#&#8203;8875](https://redirect.github.com/grpc/grpc-go/issues/8875))
- xds: validate that the sum of endpoint weights in a locality does not
exceed the maximum `uint32` value.
([#&#8203;8899](https://redirect.github.com/grpc/grpc-go/issues/8899))
- Special Thanks: [@&#8203;RAVEYUS](https://redirect.github.com/RAVEYUS)
- xds: fix incorrect proto field access in the weighted round robin
(WRR) configuration where `blackout_period` was used instead of
`weight_expiration_period`.
([#&#8203;8915](https://redirect.github.com/grpc/grpc-go/issues/8915))
- Special Thanks:
[@&#8203;gregbarasch](https://redirect.github.com/gregbarasch)
- xds/rbac: handle addresses with ports in IP matchers.
([#&#8203;8990](https://redirect.github.com/grpc/grpc-go/issues/8990))

### New Features

- ringhash: enable gRFC A76 (endpoint hash keys and request hash
headers) by default.
([#&#8203;8922](https://redirect.github.com/grpc/grpc-go/issues/8922))

### Performance Improvements

- credentials/alts: pool write buffers to reduce memory allocations and
usage.
([#&#8203;8919](https://redirect.github.com/grpc/grpc-go/issues/8919))
- grpc: enable the use of pooled write buffers for buffering HTTP/2
frame writes by default. This reduces memory usage when connections are
idle. Use the
[WithSharedWriteBuffer](https://pkg.go.dev/google.golang.org/grpc#WithSharedWriteBuffer)
dial option or the
[SharedWriteBuffer](https://pkg.go.dev/google.golang.org/grpc#SharedWriteBuffer)
server option to disable this feature.
([#&#8203;8957](https://redirect.github.com/grpc/grpc-go/issues/8957))
- xds/priority: stop caching child LB policies removed from the
configuration. This will help reduce memory and cpu usage when
localities are constantly switching between priorities.
([#&#8203;8997](https://redirect.github.com/grpc/grpc-go/issues/8997))
- mem: add a faster tiered buffer pool; use the experimental
[mem.NewBinaryTieredBufferPool](https://pkg.go.dev/google.golang.org/grpc/mem@master#NewBinaryTieredBufferPool)
function to create such pools.
([#&#8203;8775](https://redirect.github.com/grpc/grpc-go/issues/8775))

Robert Pająk a3941ff595 Release v1.42.0/v0.64.0/v0.18.0/v0.0.16 (#8006) 
### Added

- Add `go.opentelemetry.io/otel/semconv/v1.40.0` package.
The package contains semantic conventions from the `v1.40.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.40.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.39.0`. (#7985)
- Add `Err` and `SetErr` on `Record` in `go.opentelemetry.io/otel/log`
to attach an error and set record exception attributes in
`go.opentelemetry.io/otel/log/sdk`. (#7924)

### Changed

- `TracerProvider.ForceFlush` in `go.opentelemetry.io/otel/sdk/trace`
joins errors together and continues iteration through SpanProcessors as
opposed to returning the first encountered error without attempting
exports on subsequent SpanProcessors. (#7856)

### Fixed

- Fix missing `request.GetBody` in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` to
correctly handle HTTP2 GOAWAY frame. (#7931)
- Fix semconv v1.39.0 generated metric helpers skipping required
attributes when extra attributes were empty. (#7964)
- Preserve W3C TraceFlags bitmask (including the random Trace ID flag)
during trace context extraction and injection in
`go.opentelemetry.io/otel/propagation`. (#7834)

### Removed

- Drop support for [Go 1.24]. (#7984)

Tyler Yahn d5febb955e Drop support for Go 1.24 (#7984) 2026-03-02 22:25:05 +01:00
Robert Pająk 4575a9774d Release 1.41.0/0.63.0/0.17.0/0.0.15 (#7977) 
This release is the last to support [Go 1.24].
The next release will require at least [Go 1.25].

### Added

- Support testing of [Go 1.26]. (#7902)

### Fixed

- Update `Baggage` in `go.opentelemetry.io/otel/propagation` and `Parse`
and `New` in `go.opentelemetry.io/otel/baggage` to comply with W3C
Baggage specification limits.
`New` and `Parse` now return partial baggage along with an error when
limits are exceeded.
Errors from baggage extraction are reported to the global error handler.
(#7880)
