Summary

This release has several exciting features:

• Adds support for Go 1.19. Please note that this means Go 1.17 has maintenance support, and Go 1.16 has legacy support. See our version support policy for more details.
• Introduces support for propagation of trace context via SQL commenting. This experimental feature injects trace context information via sql comments in the sqlcommenter format. It is disabled by default and can be configured via the DD_TRACE_SQL_COMMENT_INJECTION_MODE environment variable or via the WithSQLCommentInjection() option.
• Introduces a WithHostname option for the profiler, which allows overriding the value used for the "host" tag
