Full Changelog: v0.9.0-alpha...v0.10.0-alpha

Release v0.9.0-alpha

Added

• The CLI flag global-impl is added.
  This flag, when used, enables the instrumentation of the OpenTelemetry default global implementation (https://pkg.go.dev/go.opentelemetry.io/otel).
  This means that all trace telemetry from this implementation that would normally be dropped will instead be recorded with the auto-instrumentation pipeline. ([#523]#523)

• Support versions v0.18.0 and v0.19.0 of golang.org/x/net. (#524)

Changed

• The instrumentation scope name for the database/sql instrumentation is now go.opentelemtry.io/auto/database/sql. (#507)
• The instrumentation scope name for the gin instrumentation is now go.opentelemtry.io/auto/github.com/gin-gonic/gin. (#507)
• The instrumentation scope name for the google.golang.org/grpc/client instrumentation is now go.opentelemtry.io/auto/google.golang.org/grpc. (#507)
• The instrumentation scope name for the google.golang.org/grpc/server instrumentation is now go.opentelemtry.io/auto/google.golang.org/grpc. (#507)
• The instrumentation scope name for the net/http/client instrumentation is now go.opentelemtry.io/auto/net/http. (#507)

• The instrumentation for client.Do was changed to instrumentation for Transport.roundTrip. (#529)

Fixed

• Support commit hash version for dependencies.
  If a dependency falls within a known version range used by instrumentation, and its offset structure has not changed, instrumentation will default to the known offset value instead of failing to run. (#503)

Release v0.8.0-alpha

Added

• Add the WithEnv InstrumentationOption to configure Instrumentation to parse the environment. The Instrumentation will no longer by default parse the environment. This option needs to be used to enable environment parsing, and the order it is passed influences the environment precedence. All options passed before this one will be overridden if there are conflicts, and those passed after will override the environment. (#417)
• Add the WithTraceExporter InstrumentationOption to configure the trace SpanExporter used by an Instrumentation. (#426)
• Add HTTP status code attribute to net/http server instrumentation. (#428)
• The instrumentation scope now includes the version of the auto-instrumentation project. (#442)
• Add a new WithSampler method allowing end-users to provide their own implementation of OpenTelemetry sampler directly through the package API. (#468).
• Add uprobes to execDC in order to instrument SQL DML. (#475)

Changed

• Documentation no longer says that SYS_PTRACE capability is needed. (#388)
• The NewInstrumentation no longer parses environment variables by default. Use the new WithEnv option to enable environment parsing. (#417)
• NewInstrumentation now requires a context.Context as its first argument. This context is used in the instantiation of exporters. (#426)
• Instrumentation now uses an OTLP over HTTP/protobuf exporter (changed from gRPC/protobuf). (#426)

Fixed

• Parse Go versions that contain GOEXPERIMENT suffixes. (#389)
• Include the schema URL for the semantic convention used in the exported resource. (#426)
• Support Go module replace directives for the golang.org/x/net within the google.golang.org/grpc server instrumentation. (#450)

Removed

• The deprecated go.opentelemetry.io/auto/examples/rolldice module is removed. (#423)

Release v0.7.0-alpha

Added

• Add WithPID config option for instrumentation. (#355)

Changed
