Robert Pająk dcfc16cebd exporters: support MAP attributes (#8453) 
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/8163

Add end-to-end exporter handling for `attribute.SLICE` in the remaining
paths that still treated it as invalid or relied on fallback formatting.

Changes:

- encode `attribute.MAP` as OTLP `AnyValue_AnyValue_KvlistValue` for
trace, log, and metric transforms
- serialize Zipkin `MAP` attributes using the non-OTLP AnyValue string
representation

Robert Pająk 3a1412d2b3 sdk/trace: avoid logging exporter endpoint configuration (#8438) 
Prevent internal trace exporter logging from including endpoint
configuration.

`MarshalLog` now keeps the existing log shape where practical, but logs
exporter/client type strings instead of recursively serializing exporter
and client internals. OTLP trace HTTP/gRPC and Zipkin exporter log
payloads no longer include endpoint URLs, embedded credentials, query
tokens, internal hostnames, or insecure transport configuration.

## Changes

- Stop recursive logging of trace exporter/client config from
`sdk/trace` span processors and `otlptrace.Exporter`.
- Remove endpoint/URL fields from OTLP trace HTTP/gRPC and Zipkin
`MarshalLog` output.
- Add regression coverage for credential-bearing endpoints not appearing
in internal log output.

### 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

- 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)

AnyValue representation for non-OTLP
protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue).
(#8170)

`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`,

- 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 -

- Narrow the newlines on assignments rule to ignore complex cases -
[#&#8203;354](https://redirect.github.com/mvdan/gofumpt/issues/354)
- Fix three bugs which caused a second gofumpt run to make changes -

Robert Pająk fa9276b15e exporters: support SLICE attributes (#8216) 
Fixes #8162

Follow-up to #8153 for `attribute.SLICE`.

Add end-to-end exporter handling for `attribute.SLICE` in the remaining
paths that still treated it as invalid or relied on fallback formatting.

Changes:

- encode `attribute.SLICE` as OTLP `AnyValue_ArrayValue` for trace, log,
and metric transforms
- serialize Zipkin `SLICE` attributes using the non-OTLP AnyValue string
representation
- add trace-side coverage for recursive `convAttrValue` slice conversion

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

Tyler Yahn b1284dbfaa Support BYTESLICE attributes across trace and exporter paths (#8153) 
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/8164

Supersedes #8042 which does not address the `trace` or `zipkin`
packages, and has unrelated support changes.

Add end-to-end handling for `attribute.BYTESLICE` in the remaining trace
and exporter paths that still dropped, invalidated, or stringified byte
slice attributes.

This change:

- preserves byte slice attributes in `trace/auto`
- encodes byte slice attributes as OTLP `AnyValue_BytesValue` in trace,
log, and metric transforms
- serializes Zipkin byte slice attributes as JSON arrays of byte values
- adds regression tests for each updated path

## Problem

`attribute.BYTESLICE` is public, but several downstream conversions
still did not handle it correctly:

- `trace/auto` dropped byte slice attributes during conversion
- OTLP trace, log, and metric transforms fell through to their invalid
default handling
- Zipkin fell back to `Value.Emit()`, which produced a base64 string
rather than an explicit byte-array representation

That made `BYTESLICE` unusable or inconsistent depending on the export
path.

## Changes

### Trace

- Handle `attribute.BYTESLICE` in `trace/auto` by converting it to an
internal telemetry bytes value.
- Add a regression test covering byte slice conversion.

### OTLP

- Handle `attribute.BYTESLICE` in:
  - trace attribute transform
  - log gRPC attribute transform
  - log HTTP attribute transform
  - metric HTTP attribute transform
  - metric gRPC attribute transform
- Update the shared log and metric transform templates so generated
outputs stay aligned.
- Add regression tests for the trace transform, both log transform
outputs, and both metric transform outputs.

### Zipkin

- Handle `attribute.BYTESLICE` explicitly in Zipkin tag serialization.
- Serialize byte slices as JSON arrays of byte values instead of base64
text.
- Add a regression test for Zipkin byte slice serialization.

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)

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)
 2026-03-06 20:13:23 +01:00

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.

 2026-02-09 09:16:59 +01:00
Tyler Yahn a3a5317c5c Release v1.40.0 (#7859) 
### Added

- Add `Enabled` method to all synchronous instrument interfaces
(`Float64Counter`, `Float64UpDownCounter`, `Float64Histogram`,
`Float64Gauge`, `Int64Counter`, `Int64UpDownCounter`, `Int64Histogram`,
`Int64Gauge`,) in `go.opentelemetry.io/otel/metric`. This stabilizes the
synchronous instrument enabled feature, allowing users to check if an
instrument will process measurements before performing computationally
expensive operations. (#7763)
- Add `AlwaysRecord` sampler in `go.opentelemetry.io/otel/sdk/trace`.
(#7724)
- Add `go.opentelemetry.io/otel/semconv/v1.39.0` package. The package
contains semantic conventions from the `v1.39.0` version of the
OpenTelemetry Semantic Conventions. See the [migration
documentation](https://github.com/open-telemetry/opentelemetry-go/blob/298cbedf256b7a9ab3c21e41fc5e3e6d6e4e94aa/semconv/v1.39.0/MIGRATION.md)
for information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.38.0.` (#7783, #7789)

### Changed

- `Exporter` in `go.opentelemetry.io/otel/exporter/prometheus` ignores
metrics with the scope `go.opentelemetry.io/contrib/bridges/prometheus`.
This prevents scrape failures when the Prometheus exporter is
misconfigured to get data from the Prometheus bridge. (#7688)
- Improve performance of concurrent histogram measurements in
`go.opentelemetry.io/otel/sdk/metric`. (#7474)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/stdout/stdoutmetric`. (#7492)
- Improve the concurrent performance of `HistogramReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar` by 4x. (#7443)
- Improve performance of concurrent synchronous gauge measurements in
`go.opentelemetry.io/otel/sdk/metric`. (#7478)
- Improve performance of concurrent exponential histogram measurements
in `go.opentelemetry.io/otel/sdk/metric`. (#7702)
- Improve the concurrent performance of `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar`. (#7447)
- The `rpc.grpc.status_code` attribute in the experimental metrics
emitted from
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` is
replaced with the `rpc.response.status_code` attribute to align with the
semantic conventions. (#7854)
- The `rpc.grpc.status_code` attribute in the experimental metrics
emitted from
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` is
replaced with the `rpc.response.status_code` attribute to align with the
semantic conventions. (#7854)

### Fixed

- Fix bad log message when key-value pairs are dropped because of key
duplication in `go.opentelemetry.io/otel/sdk/log`. (#7662)
- Fix `DroppedAttributes` on `Record` in
`go.opentelemetry.io/otel/sdk/log` to not count the non-attribute
key-value pairs dropped because of key duplication. (#7662)
- Fix `SetAttributes` on `Record` in `go.opentelemetry.io/otel/sdk/log`

Tyler Yahn 6ce14298b9 Release v1.39.0 (#7676) 
## Overview

### Added

- Greatly reduce the cost of recording metrics in
`go.opentelemetry.io/otel/sdk/metric` using hashing for map keys.
(#7175)
- Add `WithInstrumentationAttributeSet` option to
`go.opentelemetry.io/otel/log`, `go.opentelemetry.io/otel/metric`, and
`go.opentelemetry.io/otel/trace` packages. This provides a
concurrent-safe and performant alternative to
`WithInstrumentationAttributes` by accepting a pre-constructed
`attribute.Set`. (#7287)
- Add experimental observability for the Prometheus exporter in
`go.opentelemetry.io/otel/exporters/prometheus`. Check the
`go.opentelemetry.io/otel/exporters/prometheus/internal/x` package
documentation for more information. (#7345)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7353)
- Add temporality selector functions `DeltaTemporalitySelector`,
`CumulativeTemporalitySelector`, `LowMemoryTemporalitySelector` to
`go.opentelemetry.io/otel/sdk/metric`. (#7434)
- Add experimental observability metrics for simple log processor in
`go.opentelemetry.io/otel/sdk/log`. (#7548)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#7459)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#7486)
- Add experimental observability metrics for simple span processor in
`go.opentelemetry.io/otel/sdk/trace`. (#7374)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7512)
- Add experimental observability metrics for manual reader in
`go.opentelemetry.io/otel/sdk/metric`. (#7524)
- Add experimental observability metrics for periodic reader in
`go.opentelemetry.io/otel/sdk/metric`. (#7571)
- Support `OTEL_EXPORTER_OTLP_LOGS_INSECURE` and
`OTEL_EXPORTER_OTLP_INSECURE` environmental variables in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7608)
- Add `Enabled` method to the `Processor` interface in
`go.opentelemetry.io/otel/sdk/log`. All `Processor` implementations now
include an `Enabled` method. (#7639)
- The `go.opentelemetry.io/otel/semconv/v1.38.0` package. The package
contains semantic conventions from the `v1.38.0` version of the
OpenTelemetry Semantic Conventions. See the [migration
documentation](./semconv/v1.38.0/MIGRATION.md) for information on how to
upgrade from `go.opentelemetry.io/otel/semconv/v1.37.0.`(#7648)

### Changed

- `Distinct` in `go.opentelemetry.io/otel/attribute` is no longer
guaranteed to uniquely identify an attribute set. Collisions between
`Distinct` values for different Sets are possible with extremely high
cardinality (billions of series per instrument), but are highly
unlikely. (#7175)
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/trace`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `TracerOption`. (#7266)
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/meter`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `MeterOption`. (#7266)
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/log`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `LoggerOption`. (#7266)
- Rename the `OTEL_GO_X_SELF_OBSERVABILITY` environment variable to
`OTEL_GO_X_OBSERVABILITY` in `go.opentelemetry.io/otel/sdk/trace`,
`go.opentelemetry.io/otel/sdk/log`, and
`go.opentelemetry.io/otel/exporters/stdout/stdouttrace`. (#7302)
- Improve performance of histogram `Record` in
`go.opentelemetry.io/otel/sdk/metric` when min and max are disabled
using `NoMinMax`. (#7306)
- Improve error handling for dropped data during translation by using
`prometheus.NewInvalidMetric` in
`go.opentelemetry.io/otel/exporters/prometheus`. ⚠️ **Breaking Change:**
Previously, these cases were only logged and scrapes succeeded. Now,
when translation would drop data (e.g., invalid label/value), the
exporter emits a `NewInvalidMetric`, and Prometheus scrapes **fail with
HTTP 500** by default. To preserve the prior behavior (scrapes succeed
while errors are logged), configure your Prometheus HTTP handler with:
`promhttp.HandlerOpts{ ErrorHandling: promhttp.ContinueOnError }`.
(#7363)
- Replace fnv hash with xxhash in `go.opentelemetry.io/otel/attribute`
for better performance. (#7371)
- The default `TranslationStrategy` in
`go.opentelemetry.io/exporters/prometheus` is changed from
`otlptranslator.NoUTF8EscapingWithSuffixes` to
`otlptranslator.UnderscoreEscapingWithSuffixes`. (#7421)
- Improve performance of concurrent measurements in
`go.opentelemetry.io/otel/sdk/metric`. (#7427)
- Include W3C TraceFlags (bits 0–7) in the OTLP `Span.Flags` field in
`go.opentelemetry.io/exporters/otlp/otlptrace/otlptracehttp` and
`go.opentelemetry.io/exporters/otlp/otlptrace/otlptracegrpc`. (#7438)
- The `ErrorType` function in `go.opentelemetry.io/otel/semconv/v1.37.0`
now handles custom error types.
If an error implements an `ErrorType() string` method, the return value
of that method will be used as the error type. (#7442)

### Fixed

- Fix `WithInstrumentationAttributes` options in
`go.opentelemetry.io/otel/trace`, `go.opentelemetry.io/otel/metric`, and
`go.opentelemetry.io/otel/log` to properly merge attributes when passed
multiple times instead of replacing them. Attributes with duplicate keys
will use the last value passed. (#7300)
- The equality of `attribute.Set` when using the `Equal` method is not
affected by the user overriding the empty set pointed to by
`attribute.EmptySet` in `go.opentelemetry.io/otel/attribute`. (#7357)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.
(#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#7372)
- Fix `AddAttributes`, `SetAttributes`, `SetBody` on `Record` in
`go.opentelemetry.io/otel/sdk/log` to not mutate input. (#7403)
- Do not double record measurements of `RecordSet` methods in
`go.opentelemetry.io/otel/semconv/v1.37.0`. (#7655)
- Do not double record measurements of `RecordSet` methods in
`go.opentelemetry.io/otel/semconv/v1.36.0`. (#7656)

### Removed

- Drop support for [Go 1.23]. (#7274)
- Remove the `FilterProcessor` interface in
`go.opentelemetry.io/otel/sdk/log`. The `Enabled` method has been added
to the `Processor` interface instead. All `Processor` implementations
must now implement the `Enabled` method. Custom processors that do not
filter records can implement `Enabled` to return `true`. (#7639)

**Objective**:
- Performance comparison between fnv and xxhash in terms of ops/sec,
allocations and collisions
- Implement xxhash according to first objective

**Changes**:
- fnv is replaced by xxhash. 
  Perform stats:
  - **Collision**: No collision upto 100M
  - **Allocations**: Same in both cases
- **Ops/sec**: xxhash performed better in cases with medium to large
strings
 
 **Benchmarks**:

Flc゛ 80cb909774 refactor: replace context.Background() with t.Context()/b.Context() in tests (#7352) 
Based on the Go version we currently use, the dependency already
supports 1.24+, which allows using `t.Context()` and `b.Context()` in
unit tests and benchmarks respectively.

- Enable `context-background` and `context-todo` in
[`usetesting`](https://golangci-lint.run/docs/linters/configuration/#usetesting)
- Adjust the code to support linter detection

- Add `ErrorType` attribute helper function to the
`go.opentelmetry.io/otel/semconv/v1.34.0` package. (#6962)
- Add `WithAllowKeyDuplication` in `go.opentelemetry.io/otel/sdk/log`
which can be used to disable deduplication for log records. (#6968)
- Add `WithCardinalityLimit` option to configure the cardinality limit
in `go.opentelemetry.io/otel/sdk/metric`. (#6996, #7065, #7081, #7164,
#7165, #7179)
- Add `Clone` method to `Record` in `go.opentelemetry.io/otel/log` that
returns a copy of the record with no shared state. (#7001)
- Add experimental self-observability span and batch span processor
metrics in `go.opentelemetry.io/otel/sdk/trace`. Check the
`go.opentelemetry.io/otel/sdk/trace/internal/x` package documentation
for more information. (#7027, #6393, #7209)
- The `go.opentelemetry.io/otel/semconv/v1.36.0` package. The package
contains semantic conventions from the `v1.36.0` version of the
OpenTelemetry Semantic Conventions. See the [migration
documentation](./semconv/v1.36.0/MIGRATION.md) for information on how to
upgrade from `go.opentelemetry.io/otel/semconv/v1.34.0.`(#7032, #7041)
- Add support for configuring Prometheus name translation using
`WithTranslationStrategy` option in
`go.opentelemetry.io/otel/exporters/prometheus`. The current default
translation strategy when UTF-8 mode is enabled is
`NoUTF8EscapingWithSuffixes`, but a future release will change the
default strategy to `UnderscoreEscapingWithSuffixes` for compliance with
the specification. (#7111)
- Add experimental self-observability log metrics in
`go.opentelemetry.io/otel/sdk/log`. Check the
`go.opentelemetry.io/otel/sdk/log/internal/x` package documentation for
more information. (#7121)
- Add experimental self-observability trace exporter metrics in
`go.opentelemetry.io/otel/exporters/stdout/stdouttrace`. Check the

package documentation for more information. (#7133)
- Support testing of [Go 1.25]. (#7187)
- The `go.opentelemetry.io/otel/semconv/v1.37.0` package. The package
contains semantic conventions from the `v1.37.0` version of the
OpenTelemetry Semantic Conventions. See the [migration
documentation](./semconv/v1.37.0/MIGRATION.md) for information on how to
upgrade from `go.opentelemetry.io/otel/semconv/v1.36.0.`(#7254)

### Changed

- Optimize `TraceIDFromHex` and `SpanIDFromHex` in
`go.opentelemetry.io/otel/sdk/trace`. (#6791)
- Change `AssertEqual` in `go.opentelemetry.io/otel/log/logtest` to
accept `TestingT` in order to support benchmarks and fuzz tests. (#6908)
- Change `DefaultExemplarReservoirProviderSelector` in
`go.opentelemetry.io/otel/sdk/metric` to use `runtime.GOMAXPROCS(0)`
instead of `runtime.NumCPU()` for the `FixedSizeReservoirProvider`
default size. (#7094)

### Fixed

- `SetBody` method of `Record` in `go.opentelemetry.io/otel/sdk/log` now
deduplicates key-value collections (`log.Value` of `log.KindMap` from
`go.opentelemetry.io/otel/log`). (#7002)
- Fix `go.opentelemetry.io/otel/exporters/prometheus` to not append a
suffix if it's already present in metric name. (#7088)
- Fix the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace`
self-observability component type and name. (#7195)
- Fix partial export count metric in
`go.opentelemetry.io/otel/exporters/stdout/stdouttrace`. (#7199)

preferring `WithTranslationStrategy` instead. (#7111)
- Deprecate support for `OTEL_GO_X_CARDINALITY_LIMIT` environment
variable in `go.opentelemetry.io/otel/sdk/metric`. Use
`WithCardinalityLimit` option instead. (#7166)

[`v1.11.1`](https://redirect.github.com/stretchr/testify/releases/tag/v1.11.1)

[Compare
Source](https://redirect.github.com/stretchr/testify/compare/v1.11.0...v1.11.1)

This release fixes
[#&#8203;1785](https://redirect.github.com/stretchr/testify/issues/1785)
introduced in v1.11.0 where expected argument values implementing the
stringer interface (`String() string`) with a method which mutates their
value, when passed to mock.Mock.On (`m.On("Method",
<expected>).Return()`) or actual argument values passed to
mock.Mock.Called may no longer match one another where they previously
did match. The behaviour prior to v1.11.0 where the stringer is always
called is restored. Future testify releases may not call the stringer
method at all in this case.

#### What's Changed

- Backport
[#&#8203;1786](https://redirect.github.com/stretchr/testify/issues/1786)
to release/1.11: mock: revert to pre-v1.11.0 argument matching behavior
