Release v1.22.0/v0.45.0

[MadVikingGod]

Added

• The go.opentelemetry.io/otel/semconv/v1.22.0 package.
  The package contains semantic conventions from the v1.22.0 version of the OpenTelemetry Semantic Conventions. (Add semconv v1.22.0 #4735)
• The go.opentelemetry.io/otel/semconv/v1.23.0 package.
  The package contains semantic conventions from the v1.23.0 version of the OpenTelemetry Semantic Conventions. (Add semconv/v1.23.0 #4746)
• The go.opentelemetry.io/otel/semconv/v1.23.1 package.
  The package contains semantic conventions from the v1.23.1 version of the OpenTelemetry Semantic Conventions. (Add semconv/v1.23.1 #4749)
• The go.opentelemetry.io/otel/semconv/v1.24.0 package.
  The package contains semantic conventions from the v1.24.0 version of the OpenTelemetry Semantic Conventions. (Add semconv v1.24.0 #4770)
• Add WithResourceAsConstantLabels option to apply resource attributes for every metric emitted by the Prometheus exporter. (add option for resource attributes in metrics for prometheus exporter #4733)
• Experimental cardinality limiting is added to the metric SDK.
  See metric documentation for more information about this feature and how to enable it. (Add cardinality limiting to the metric SDK as an experimental feature #4457)
• Add NewMemberRaw and NewKeyValuePropertyRaw in go.opentelemetry.io/otel/baggage. (baggage: Add NewMemberRaw and NewKeyValuePropertyRaw #4804)

Changed

• Upgrade all use of go.opentelemetry.io/otel/semconv to use v1.24.0. (Upgrade use of semconv to v1.24.0 #4754)
• Update transformations in go.opentelemetry.io/otel/exporters/zipkin to follow v1.19.0 version of the OpenTelemetry specification. (Upgrade use of semconv to v1.24.0 #4754)
• Record synchronous measurements when the passed context is canceled instead of dropping in go.opentelemetry.io/otel/sdk/metric.
  If you do not want to make a measurement when the context is cancelled, you need to handle it yourself (e.g if ctx.Err() != nil). (sdk/metric: Record measurements when context is done #4671)
• Improve go.opentelemetry.io/otel/trace.TraceState's performance. (improve tracestate performance #4722)
• Improve go.opentelemetry.io/otel/propagation.TraceContext's performance. (improve trace_context performance #4721)
• Improve go.opentelemetry.io/otel/baggage performance. (baggage: Improve performance #4743)
• Improve performance of the (*Set).Filter method in go.opentelemetry.io/otel/attribute when the passed filter does not filter out any attributes from the set. (Optimize (attribute.Set).Filter for no filtered case #4774)
• Member.String in go.opentelemetry.io/otel/baggage percent-encodes only when necessary. (baggage: Member.String encodes only when necessary #4775)
• Property.Value in go.opentelemetry.io/otel/baggage now returns a raw string instead of a percent-encoded value. (baggage: Add NewMemberRaw and NewKeyValuePropertyRaw #4804)

Fixed

• Fix Parse in go.opentelemetry.io/otel/baggage to validate member value before percent-decoding. (baggage: Fix Parse to validate member value before percent-decoding #4755)
• Fix whitespace encoding of Member.String in go.opentelemetry.io/otel/baggage. (baggage: Fix escaping in Member.String #4756)
• Fix baggage item key so that it is not canonicalized in go.opentelemetry.io/otel/bridge/opentracing. (bridge/opentracing: fix baggage item key is canonicalized #4776)
• Fix go.opentelemetry.io/otel/bridge/opentracing to properly handle baggage values that requires escaping during propagation. (baggage: Add NewMemberRaw and NewKeyValuePropertyRaw #4804)
• Fix a bug where using multiple readers resulted in incorrect asynchronous counter values in go.opentelemetry.io/otel/sdk/metric. (Fix multi-reader observable counter double-counting bug #4742)
