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

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`
to not log that attributes are dropped when they are actually not
dropped. (#7662)
- `WithHostID` detector in `go.opentelemetry.io/otel/sdk/resource` to
use full path for `ioreg` command on Darwin (macOS). (#7818)
- Fix missing `request.GetBody` in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` to
correctly handle HTTP2 GOAWAY frame. (#7794)

### Deprecated

- Deprecate `go.opentelemetry.io/otel/exporters/zipkin`. For more
information, see the [OTel blog post deprecating the Zipkin
exporter](https://opentelemetry.io/blog/2025/deprecating-zipkin-exporters/).

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)

**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

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

  - `RPCGRPCRequestMetadata`
  - `RPCGRPCResponseMetadata`
- 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)

### Deprecated

- Deprecate `WithoutUnits` and `WithoutCounterSuffixes` options,
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)

Damien Mathieu a85ae98dce Release v1.36.0/v0.58.0/v0.12.0 (#6793)
# Overview

Closes https://github.com/open-telemetry/opentelemetry-go/issues/6786

### Added

- Add exponential histogram support in
`go.opentelemetry.io/otel/exporters/prometheus`. (#6421)
- The `go.opentelemetry.io/otel/semconv/v1.31.0` package.
The package contains semantic conventions from the `v1.31.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.31.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.30.0`. (#6479)
- Add `Recording`, `Scope`, and `Record` types in
`go.opentelemetry.io/otel/log/logtest`. (#6507)
- Add `WithHTTPClient` option to configure the `http.Client` used by
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#6751)
- Add `WithHTTPClient` option to configure the `http.Client` used by
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#6752)
- Add `WithHTTPClient` option to configure the `http.Client` used by
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6688)
- Add `ValuesGetter` in `go.opentelemetry.io/otel/propagation`, a
`TextMapCarrier` that supports retrieving multiple values for a single
key. (#5973)
- Add `Values` method to `HeaderCarrier` to implement the new
`ValuesGetter` interface in `go.opentelemetry.io/otel/propagation`.
(#5973)
- Update `Baggage` in `go.opentelemetry.io/otel/propagation` to retrieve
multiple values for a key when the carrier implements `ValuesGetter`.
(#5973)
- Add `AssertEqual` function in `go.opentelemetry.io/otel/log/logtest`.
(#6662)
- The `go.opentelemetry.io/otel/semconv/v1.32.0` package.
The package contains semantic conventions from the `v1.32.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.32.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.31.0`(#6782)
- Add `Transform` option in `go.opentelemetry.io/otel/log/logtest`.
(#6794)
- Add `Desc` option in `go.opentelemetry.io/otel/log/logtest`. (#6796)

### Removed

- Drop support for [Go 1.22]. (#6381, #6418)
- Remove `Resource` field from `EnabledParameters` in
`go.opentelemetry.io/otel/sdk/log`. (#6494)
- Remove `RecordFactory` type from
`go.opentelemetry.io/otel/log/logtest`. (#6492)
- Remove `ScopeRecords`, `EmittedRecord`, and `RecordFactory` types from
`go.opentelemetry.io/otel/log/logtest`. (#6507)
- Remove `AssertRecordEqual` function in
`go.opentelemetry.io/otel/log/logtest`, use `AssertEqual` instead.
(#6662)

### Changed

- ⚠️ Update `github.com/prometheus/client_golang` to `v1.21.1`, which
changes the `NameValidationScheme` to `UTF8Validation`.
This allows metrics names to keep original delimiters (e.g. `.`), rather
than replacing with underscores.
This can be reverted by setting
`github.com/prometheus/common/model.NameValidationScheme` to
`LegacyValidation` in `github.com/prometheus/common/model`. (#6433)
- Initialize map with `len(keys)` in `NewAllowKeysFilter` and
`NewDenyKeysFilter` to avoid unnecessary allocations in
`go.opentelemetry.io/otel/attribute`. (#6455)
- `go.opentelemetry.io/otel/log/logtest` is now a separate Go module.
(#6465)
- `go.opentelemetry.io/otel/sdk/log/logtest` is now a separate Go
module. (#6466)
- `Recorder` in `go.opentelemetry.io/otel/log/logtest` no longer
separately stores records emitted by loggers with the same
instrumentation scope. (#6507)
- Improve performance of `BatchProcessor` in
`go.opentelemetry.io/otel/sdk/log` by not exporting when exporter cannot
accept more. (#6569, #6641)

### Deprecated

- Deprecate support for `model.LegacyValidation` for
`go.opentelemetry.io/otel/exporters/prometheus`. (#6449)

### Fixes

- Stop percent encoding header environment variables in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6392)
- Ensure the `noopSpan.tracerProvider` method is not inlined in
`go.opentelemetry.io/otel/trace` so the `go.opentelemetry.io/auto`
instrumentation can instrument non-recording spans. (#6456)
- Use a `sync.Pool` instead of allocating `metricdata.ResourceMetrics`
in `go.opentelemetry.io/otel/exporters/prometheus`. (#6472)

Sam Xie 09ff8b107a Drop support for Go 1.22 (#6381) 2025-03-05 22:23:10 -08:00
Sam Xie 5ba5e7a449 Release v1.35.0/v0.57.0/v0.11.0 (#6407)
## Overview

This release is the last to support [Go 1.22].
The next release will require at least [Go 1.23].

### Added

- Add `ValueFromAttribute` and `KeyValueFromAttribute` in
`go.opentelemetry.io/otel/log`. (#6180)
- Add `EventName` and `SetEventName` to `Record` in
`go.opentelemetry.io/otel/log`. (#6187)
- Add `EventName` to `RecordFactory` in
`go.opentelemetry.io/otel/log/logtest`. (#6187)
- `AssertRecordEqual` in `go.opentelemetry.io/otel/log/logtest` checks
`Record.EventName`. (#6187)
- Add `EventName` and `SetEventName` to `Record` in
`go.opentelemetry.io/otel/sdk/log`. (#6193)
- Add `EventName` to `RecordFactory` in
`go.opentelemetry.io/otel/sdk/log/logtest`. (#6193)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#6211)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6211)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/stdout/stdoutlog` (#6210)
- The `go.opentelemetry.io/otel/semconv/v1.28.0` package.
The package contains semantic conventions from the `v1.28.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.28.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.27.0`(#6236)
- The `go.opentelemetry.io/otel/semconv/v1.30.0` package.
The package contains semantic conventions from the `v1.30.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.30.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.28.0`(#6240)
- Document the pitfalls of using `Resource` as a comparable type.
`Resource.Equal` and `Resource.Equivalent` should be used instead.
(#6272)
- Support [Go 1.24]. (#6304)
- Add `FilterProcessor` and `EnabledParameters` in
`go.opentelemetry.io/otel/sdk/log`.
It replaces
`go.opentelemetry.io/otel/sdk/log/internal/x.FilterProcessor`.
Compared to previous version it additionally gives the possibility to
filter by resource and instrumentation scope. (#6317)

### Changed

- Update `github.com/prometheus/common` to v0.62.0., which changes the
`NameValidationScheme` to `NoEscaping`. This allows metrics names to
keep original delimiters (e.g. `.`), rather than replacing with
underscores. This is controlled by the `Content-Type` header, or can be
reverted by setting `NameValidationScheme` to `LegacyValidation` in
`github.com/prometheus/common/model`. (#6198)

### Fixes

- Eliminate goroutine leak for the processor returned by
`NewSimpleSpanProcessor` when `Shutdown` is called and the passed `ctx`
is canceled and `SpanExporter.Shutdown` has not returned. (#6368)
- Eliminate goroutine leak for the processor returned by
`NewBatchSpanProcessor` when `ForceFlush` is called and the passed `ctx`
is canceled and `SpanExporter.Export` has not returned. (#6369)
