 ### Changed
 
-- Updated Jaeger Environment Variable: `OTEL_EXPORTER_JAEGER_ENDPOINT` to have a default value of 
-  `http://localhost:14250` when not set, in compliance with OTel spec. Changed the function `WithCollectorEndpoint`
-  in the Jaeger exporter package to no longer accept an endpoint as an argument. 
-  The endpoint can be passed in as a `CollectorEndpointOption` using the `WithEndpoint` function or 
-  specified through the `OTEL_EXPORTER_JAEGER_ENDPOINT` environment variable. (#1824)
-- Modify Zipkin Exporter default service name, use default resouce's serviceName instead of empty. (#1777)
-- Updated Jaeger Environment Variables: `JAEGER_ENDPOINT`, `JAEGER_USER`, `JAEGER_PASSWORD`

-  in compliance with OTel spec (#1752)
 - Span `RecordError` now records an `exception` event to comply with the semantic convention specification. (#1492)
 - Jaeger exporter was updated to use thrift v0.14.1. (#1712)
 - Migrate from using internally built and maintained version of the OTLP to the one hosted at `go.opentelemetry.io/proto/otlp`. (#1713)

 - The storage of a local or remote Span in a `context.Context` using its SpanContext is unified to store just the current Span.
   The Span's SpanContext can now self-identify as being remote or not.
   This means that `"go.opentelemetry.io/otel/trace".ContextWithRemoteSpanContext` will now overwrite any existing current Span, not just existing remote Spans, and make it the current Span in a `context.Context`. (#1731)
+- Improve OTLP/gRPC exporter connection errors. (#1737)
 - Information about a parent span context in a `"go.opentelemetry.io/otel/export/trace".SpanSnapshot` is unified in a new `Parent` field.
   The existing `ParentSpanID` and `HasRemoteParent` fields are removed in favor of this. (#1748)
 - The `ParentContext` field of the `"go.opentelemetry.io/otel/sdk/trace".SamplingParameters` is updated to hold a `context.Context` containing the parent span.
   This changes it to make `SamplingParameters` conform with the OpenTelemetry specification. (#1749)
+- Updated Jaeger Environment Variables: `JAEGER_ENDPOINT`, `JAEGER_USER`, `JAEGER_PASSWORD`
+  to `OTEL_EXPORTER_JAEGER_ENDPOINT`, `OTEL_EXPORTER_JAEGER_USER`, `OTEL_EXPORTER_JAEGER_PASSWORD`

 - Modify `BatchSpanProcessor.ForceFlush` to abort after timeout/cancellation. (#1757)
-- Improve OTLP/gRPC exporter connection errors. (#1737)
 - The `DroppedAttributeCount` field of the `Span` in the `go.opentelemetry.io/otel` package now only represents the number of attributes dropped for the span itself.
   It no longer is a conglomerate of itself, events, and link attributes that have been dropped. (#1771)
 - Make `ExportSpans` in Jaeger Exporter honor context deadline. (#1773)
+- Modify Zipkin Exporter default service name, use default resouce's serviceName instead of empty. (#1777)
 - The `go.opentelemetry.io/otel/sdk/export/trace` package is merged into the `go.opentelemetry.io/otel/sdk/trace` package. (#1778)
 - The prometheus.InstallNewPipeline example is moved from comment to example test (#1796)
 - The convenience functions for the stdout exporter have been updated to return the `TracerProvider` implementation and enable the shutdown of the exporter. (#1800)
 - Replace the flush function returned from the Jaeger exporter's convenience creation functions (`InstallNewPipeline` and `NewExportPipeline`) with the `TracerProvider` implementation they create.
   This enables the caller to shutdown and flush using the related `TracerProvider` methods. (#1822)
+- Updated the Jaeger exporter to have a default enpoint, `http://localhost:14250`, for the collector. (#1824)
+- Changed the function `WithCollectorEndpoint` in the Jaeger exporter to no longer accept an endpoint as an argument.
+  The endpoint can be passed with the `CollectorEndpointOption` using the `WithEndpoint` function or by setting the `OTEL_EXPORTER_JAEGER_ENDPOINT` environment variable value appropriately. (#1824)
 - The Jaeger exporter no longer batches exported spans itself, instead it relies on the SDK's `BatchSpanProcessor` for this functionality. (#1830)
 - The Jaeger exporter creation functions (`NewRawExporter`, `NewExportPipeline`, and `InstallNewPipeline`) no longer accept the removed `Option` type as a variadic argument. (#1830)
 
 ### Removed
 
-- Removed the functions `CollectorEndpointFromEnv` and `WithCollectorEndpointOptionFromEnv` from the Jaeger exporter.
-  These functions for retrieving specific environment variable values are redundant of other internal functions and
-  are not intended for end user use. (#1824)
 - Removed Jaeger Environment variables: `JAEGER_SERVICE_NAME`, `JAEGER_DISABLED`, `JAEGER_TAGS`
   These environment variables will no longer be used to override values of the Jaeger exporter (#1752)
 - No longer set the links for a `Span` in `go.opentelemetry.io/otel/sdk/trace` that is configured to be a new root.
