7.0.0 (2022-08-10)

⚠ BREAKING CHANGES

• update library to use Node 12 (#1442)
• drop support for node.js 8.x (#1239)
• When initialized with clsMechanism: 'none', calling Tracer#createChildSpan will potentially result in a warning, as these spans are considered to be uncorrelated. To ensure that warnings do not occur, disable any plugins that patch modules that create outgoing RPCs (gRPC, HTTP client and database calls). (Use of the custom span API Tracer#createChildSpan is not recommended in this configuration -- use RootSpan#createChildSpan instead.)
• This change modifies/removes APIs that assume a particular format for trace context headers; in other words, any place where the user would deal with a stringified trace context, they would now deal with a TraceContext object instead. This affects three APIs: getResponseTraceContext (input/output has changed from string to TraceContext), createRootSpan (input RootSpanOptions now accepts a TraceContext instead of a string in the traceContext field), and Span#getTraceContext (output has changed from string to TraceContext).
• contextHeaderBehavior and ignoreContextHeader now act independently of one another. The former controls how a sampling decision is made based on incoming context header, and the latter controls whether trace context is propagated to the current request.
• upgrade engines field to >=8.10.0 (#1011)
• TraceAgent has been renamed to Tracer. In plugins, Patch has been renamed Monkeypatch, and Patch is now Monkeypatch|Intercept (this is a rename of Instrumentation). There are no user-visible JS changes.
• The change in distributed trace context propagation across gRPC is not backwards-compatible. In other words, distributed tracing will not work between two Node instances communicating using gRPC with v2 and v3 of the Trace Agent, respectively.
• This commit drops support for Node 4 and 9.
