End User Changelog

all: Change metric units to be singular to match OTel specification, e.g. {requests} -> {request} (#14753)

cmd/mdatagen: Add deprecated_type field to allow specifying an alias for component types. (#14718)
cmd/mdatagen: Generate entity-scoped MetricsBuilder API that enforces entity-metric associations at compile time (#14659)
cmd/mdatagen: Skip generating reaggregation config options for metrics that have no aggregatable attributes. (#14689)
pkg/service: The internal status reporter no longer drops repeated Ok and RecoverableError statuses (#14282)
Status events can now carry metadata and there's value in allowing them to be emitted despite the status value itself
not changing.

cmd/builder: Add .exe to output binary names when building for Windows targets. (#12591)
exporter/debug: Add printing of metric metadata in detailed verbosity. (#14667)
exporter/otlp_grpc: Prevent nil pointer panic when push methods are called before the OTLP exporter initializes its gRPC clients. (#14663)
When the sending queue and retry are disabled, calling ConsumeTraces,
ConsumeMetrics, ConsumeLogs, or ConsumeProfiles before the OTLP exporter
initializes its gRPC clients could cause a nil pointer dereference panic.
The push methods now return an error instead of panicking.
exporter/otlp_http: Show the actual destination URL in error messages when request URL is modified by middleware. (#14673)
Unwraps the *url.Error returned by http.Client.Do() to prevent misleading error logs when a middleware extension dynamically updates the endpoint.
pdata/pprofile: Switch the dictionary of dictionary tables entries only once when merging profiles (#14709)
For dictionary table data, we used to switch their dictionaries when doing
the switch for the data that uses them.
However, when an entry is associated with multiple other data (several
samples can use the same stack), we would have been switching the
dictionaries of the entry multiple times.
We now switch dictionaries for dictionary table data only once, before
switching the resource profiles.

cmd/mdatagen: Generate a per-metric config type <MetricName>Config for each metric when reaggregation_enabled: true (#14689)
Metrics with aggregatable attributes get AggregationStrategy and EnabledAttributes []<MetricName>AttributeKey
fields; others get Enabled only. Typed attribute key constants (e.g. DefaultMetricAttributeKeyStringAttr)
replace []string, eliminating runtime attribute slice allocations. Validation errors now list valid attributes
and strategies by name. Components using reaggregation_enabled: true will need to update references to MetricConfig.
pdata/pprofile: Update protoID for message Sample fields (#14652)

cmd/mdatagen: Extend mdatagen tool to generate go config structs for OpenTelemetry collector components. (#14561)
The component config go code is generated from config section of the metadata.yaml file.
cmd/mdatagen: Extend mdatagen tool to generate config JSON schema for OpenTelemetry components. (#14543)
The component config JSON schema is generated from config section of the metadata.yaml file.
cmd/mdatagen: Schema generation for mdatagen-controlled config parts (#14562)
The schema is generated in separate yaml file and used to create full component schema.
pdata/pprofile: Implement reference based attributes in Profiles (#14546)
pkg/pdata: Upgrade the OTLP protobuf definitions to version 1.10.0 (#14766)
pkg/service: The internal status reporter no longer drops repeated Ok and RecoverableError statuses (#14282)
Status events can now carry metadata and there's value in allowing them to be emitted despite the status value itself
not changing.
pkg/xexporterhelper: Add logic to cleanup partitions from memory which are not being used for specific time period. (#14526)
pkg/xpdata: Add NewEntity constructor, Entity.CopyToResource, and EntityAttributeMap.All to pdata/xpdata/entity (#14659)

cmd/mdatagen: Preserve custom extensions (e.g., x-customType, x-pointer) during schema reference resolution. (#14713, #14565)
Fixes an issue where custom properties defined locally on a node were
overwritten and lost when resolving a $ref to an external/internal schema.
pkg/xexporterhelper: Fix race when partition is being removed from LRU and new items are being added at the same time. (#14526)
