8.0.0-rc.2

Fixes

• Fix incoming defer sampling decision sentry-trace header (#3942)
  • A sentry-trace header that only contains trace ID and span ID but no sampled flag (-1, -0 suffix) means the receiving system can make its own sampling decision
  • When generating sentry-trace header from PropagationContext we now copy the sampled flag.
  • In TransactionContext.fromPropagationContext when there is no parent sampling decision, keep the decision null so a new sampling decision is made instead of defaulting to false
• Defer sampling decision by setting sampled to null in PropagationContext when using OpenTelemetry in case of an incoming defer sampling sentry-trace header. (#3945)
• Build PropagationContext from SamplingDecision made by SentrySampler instead of parsing headers and potentially ignoring a sampling decision in case a sentry-trace header comes in with deferred sampling decision. (#3947)
• Let OpenTelemetry handle extracting and injecting tracing information (#3953)
  • Our integrations no longer call .continueTrace and also do not inject tracing headers if the integration has been added to ignoredSpanOrigins
• Changes up to 7.18.1 have been merged and are now included as well
