Incubating

• Implement environment variable context propagation carriers (#8074)
• Deprecate ExtendedAttributes, ExtendedAttributeKey, ExtendedAttributeType, ExtendedAttributesBuilder (#8060)

SDK

Traces

• Disable warning when using TraceIdRatioBasedSampler as root sampler (#8065)
• User-supplied attributes take precedence over exception-derived attributes (#7993)

Metrics

• Split out cumulative vs. delta storage (#8015)
• Add metrics for PeriodicMetricReader (#8038)
• Allow configuring min/max in histograms (#8095)
• Remove deprecated otel.experimental.metrics.cardinality.limit property (#8124)

If a glob char (* or ?) was present, it was evaluated with case sensitivity. If no glob chars were present, it was evaluated with case insensitivity. Now, all are consistently evaluated with case sensitivity. (#8152)
