Important changes:
-
[API] Add InstrumentationScope attributes in TracerProvider::GetTracer() #2371
- TracerProvider::GetTracer() now accepts InstrumentationScope attributes.
- Because this is an
ABI
breaking change, the fix is only available with theCMake
optionWITH_ABI_VERSION_2=ON
. - When building with
CMake
optionWITH_ABI_VERSION_1=ON
(by default) theABI
is unchanged, and the fix is not available.
-
[API] Add a new AddLink() operation to Span #2380
- New
API
Span::AddLink() adds a single link to a span. - New
API
Span::AddLinks() adds multiple links to a span. - Because this is an
ABI
breaking change, the fix is only available with theCMake
optionWITH_ABI_VERSION_2=ON
. - When building with
CMake
optionWITH_ABI_VERSION_1=ON
(by default) theABI
is unchanged, and the fix is not available.
- New
-
[BUILD] Make WITH_OTLP_HTTP_SSL_PREVIEW mainstream #2378
- The experimental
CMake
optionWITH_OTLP_HTTP_SSL_PREVIEW
is now promoted to stable. The default is changed toON
. - The experimental
CMake
optionWITH_OTLP_HTTP_SSL_TLS_PREVIEW
is now promoted to stable. The default is changed toON
. - These build options are scheduled to be removed by the next release, building without SSL/TLS will no longer be possible.

-
[EXPORTER] Rework OTLP/HTTP and OTLP/GRPC exporter options #2388
OtlpGrpcMetricExporterOptions
used to honor_TRACES_
environment variables, instead of_METRICS_
environment variables.- The implementation of
OtlpGrpcMetricExporterOptions
is now fixed. - Please check configuration variables,
to make sure
_METRICS_
variables are set as expected.
Breaking changes:
-
[BUILD] Remove WITH_REMOVE_METER_PREVIEW, use WITH_ABI_VERSION_2 instead #2370
- The experimental
CMake
optionWITH_REMOVE_METER_PREVIEW
is removed, use optionWITH_ABI_VERSION_2
instead.
- The experimental
-
[BUILD] enum CanonicalCode names too generic... conflict with old C defines #2385
- Header file
opentelemetry/trace/canonical_code.h
is unused, and is now removed. - This header should not be included directly in an application. If this is the case, please remove any remaining include directives.
- Header file
-
[BUILD] Fix exported definitions when building DLL with STL #2387
- The MeterSelector, MeterSelectorFactory, InstrumentSelector, and InstrumentSelectorFactory APIs now use const std::string& instead of nostd::string_view for name, version and schema to maintain a single export definition for DLL.
-
[EXPORTER] Rework OTLP/HTTP and OTLP/GRPC exporter options #2388
OtlpGrpcLogRecordExporter
incorrectly usedOtlpGrpcExporterOptions
, which are options for traces and not logs.- This created a bug: the
OtlpGrpcLogRecordExporter
honors_TRACES_
environment variables, instead of_LOGS_
environment variables. OtlpGrpcLogRecordExporter
is changed to useOtlpGrpcLogRecordExporterOptions
instead, fixing the bug.- User code that initializes the SDK with a GRPC Log exporter,
and uses exporter options, should adjust to replace
OtlpGrpcExporterOptions
withOtlpGrpcLogRecordExporterOptions
. - Please check configuration variables,
to make sure
_LOGS_
variables are set as expected.

CMAKE
, the boolean optionWITH_STL
as changed to an option that accepts the valuesOFF
,ON

WITH_STL=OFF
instead (this is the default). - Applications makefiles that did set WITH_STL need to use
WITH_STL=ON
instead, or may choose to pick a specific value. - In the
API
header files, the preprocessor symbolHAVE_CPP_STDLIB
is no longer used. - Applications that did set
HAVE_CPP_STDLIB
before, need to setOPENTELEMETRY_STL_VERSION=<version>
instead, to build with a specific STL version (2011, 2014, 2017, 2020, 2023). - The opentelemetry-cpp makefile no longer sets CMAKE_CXX_STANDARD by itself. Instead, the CMAKE_CXX_STANDARD and/or compiler options -stdc++ used by the caller are honored.
- Applications that set neither CMAKE_CXX_STANDARD nor -stdc++ options may need to provide a C++ standard in their makefiles.

Important changes:
- [EXPORTER] GRPC endpoint scheme should take precedence over OTEL_EXPORTER_OTLP_TRACES_INSECURE
#2060
- The logic to decide whether or not an OTLP GRPC exporter uses SSL has
changed to comply with the specification:
- Before this change, the following settings were evaluated, in order:
- OTEL_EXPORTER_OTLP_TRACES_INSECURE (starting with 1.8.3)
- OTEL_EXPORTER_OTLP_INSECURE (starting with 1.8.3)
- OTEL_EXPORTER_OTLP_TRACES_SSL_ENABLE
- OTEL_EXPORTER_OTLP_SSL_ENABLE
- With this change, the following settings are evaluated, in order:
- The GRPC endpoint scheme, if provided:
- "https" imply with SSL,
- "http" imply without ssl.
- OTEL_EXPORTER_OTLP_TRACES_INSECURE
- OTEL_EXPORTER_OTLP_INSECURE
- OTEL_EXPORTER_OTLP_TRACES_SSL_ENABLE
- OTEL_EXPORTER_OTLP_SSL_ENABLE
- The GRPC endpoint scheme, if provided:
- As a result, a behavior change for GRPC SSL is possible, because the endpoint scheme now takes precedence. Please verify configuration settings for the GRPC endpoint.
- Before this change, the following settings were evaluated, in order:
- The logic to decide whether or not an OTLP GRPC exporter uses SSL has
changed to comply with the specification:
- [SDK] Add
ForceFlush
for allLogRecordExporter
andSpanExporter
#2000LogRecordExporter
andSpanExporter
add a new virtual functionForceFlush
, and if users implement any customizedLogRecordExporter
andSpanExporter
, they should also implement this function. There should be no impact if users only use factory to create exporters.

Deprecations:
- [MAINTAINER DOC] Define and document a deprecation process,
#1923
- A new file, DEPRECATED list all the code currently deprecated.
- A new deprecation process details the plan to deprecate and later remove code.
- [DEPRECATION] Deprecate the Jaeger exporter
#1923
- The Jaeger Exporter is deprecated, see DEPRECATED for details.
Important changes:
- [BUILD] Cleanup CMake makefiles for CURL usage
#1916
- CMake option
WITH_OTLP_HTTP
- Before this change, the CMake option
WITH_OTLP_HTTP
was unpredictable, sometime set to ON and sometime set to OFF by default, depending on whether a CURL package was found or not. The optionWITH_OTLP_HTTP
was sometime not displayed in the ccmake UI, making it impossible to even discover there is an option of that name. - With this change, CMake option
WITH_OTLP_HTTP
is always OFF by default. WITH_OTLP_HTTP MUST be set to ON explicitly to build the OTLP HTTP exporter. The option is always visible in the ccmake UI.
- Before this change, the CMake option
- CMake option
BUILD_W3CTRACECONTEXT_TEST
- Before this change, the W3C trace context tests were built, or not, in an unpredictable way, depending on the presence, or not, of a CURL package. In particular, the build could ignore the W3C trace context tests even when BUILD_W3CTRACECONTEXT_TEST=ON.
- With this change, option BUILD_W3CTRACECONTEXT_TEST is honored.
- HTTP client/server examples
- Before this change, the HTTP client/server examples were built, or not, in an unpredictable way, depending on the presence, or not, of a CURL package.
- With this change, a new option
WITH_EXAMPLES_HTTP
is used to build the HTTP client/server examples.

Deprecation notes:
- [Deprecation] Deprecate experimental semantic conventions
#1744
-
The file
api/include/opentelemetry/trace/experimental_semantic_conventions.h
is deprecated, and will be removed in a future release. Use fileapi/include/opentelemetry/trace/semantic_conventions.h
instead. -
The file
sdk/include/opentelemetry/sdk/resource/experimental_semantic_conventions.h
is deprecated, and will be removed in a future release. Use filesdk/include/opentelemetry/sdk/resource/semantic_conventions.h
instead. -
The function, declared in the global namespace
uint32_t hashCode(const char *str, uint32_t h = 0)
is deprecated, and will be removed in a future release. No replacement will be provided. Note that functionopentelemetry::utils::hashCode
, declared in the ETW exporter, is not affected by this deprecation.
-
Breaking changes:
- [SEMANTIC CONVENTIONS] Upgrade to version 1.15.0
#1761
- Naming of semantic conventions has changed from uppercase constants,
like
SemanticConventions::SERVICE_NAME
, to camel case, likeSemanticConventions::kServiceName
. This is necessary to avoid collisions with macros in general, which breaks the build on some platforms. - Semantic conventions are flagged as experimental, which is why this change is done in this release.

opentelemetry-proto to 0.17.0, which includes some breaking change in the
protocol, like
this. This
makes name
parameter for our log API unnecessary. However, this parameter is
marked deprecated instead of being removed in this release, and it will be
removed in future release.
