### Added
- The `IsEmpty` method is added to the `Instrument` type in
`go.opentelemetry.io/otel/sdk/metric`.
This method is used to check if an `Instrument` instance is a
zero-value. (#5431)
- Store and provide the emitted `context.Context` in `ScopeRecords` of
`go.opentelemetry.io/otel/sdk/log/logtest`. (#5468)
- The `go.opentelemetry.io/otel/semconv/v1.26.0` package.
The package contains semantic conventions from the `v1.26.0` version of
the OpenTelemetry Semantic Conventions. (#5476)
- The `AssertRecordEqual` method to
`go.opentelemetry.io/otel/log/logtest` to allow comparison of two log
records in tests. (#5499)
- The `WithHeaders` option to
`go.opentelemetry.io/otel/exporters/zipkin` to allow configuring custom
http headers while exporting spans. (#5530)
### Changed
- `Tracer.Start` in `go.opentelemetry.io/otel/trace/noop` no longer
allocates a span for empty span context. (#5457)
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/example/otel-collector`. (#5490)
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/example/zipkin`. (#5490)
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/exporters/zipkin`. (#5490)
- The exporter no longer exports the deprecated "otel.library.name" or
"otel.library.version" attributes.
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/sdk/resource`. (#5490)
- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to
`go.opentelemetry.io/otel/semconv/v1.26.0` in
`go.opentelemetry.io/otel/sdk/trace`. (#5490)
- `SimpleProcessor.OnEmit` in `go.opentelemetry.io/otel/sdk/log` no
longer allocates a slice which makes it possible to have a
zero-allocation log processing using `SimpleProcessor`. (#5493)
- Use non-generic functions in the `Start` method of
`"go.opentelemetry.io/otel/sdk/trace".Trace` to reduce memory
allocation. (#5497)
- `service.instance.id` is populated for a `Resource` created with
`"go.opentelemetry.io/otel/sdk/resource".Default` with a default value
when `OTEL_GO_X_RESOURCE` is set. (#5520)
- Improve performance of metric instruments in
`go.opentelemetry.io/otel/sdk/metric` by removing unnecessary calls to
`time.Now`. (#5545)
### Fixed
- Log a warning to the OpenTelemetry internal logger when a `Record` in
`go.opentelemetry.io/otel/sdk/log` drops an attribute due to a limit
being reached. (#5376)
- Identify the `Tracer` returned from the global `TracerProvider` in
`go.opentelemetry.io/otel/global` with its schema URL. (#5426)
- Identify the `Meter` returned from the global `MeterProvider` in
`go.opentelemetry.io/otel/global` with its schema URL. (#5426)
- Log a warning to the OpenTelemetry internal logger when a `Span` in
`go.opentelemetry.io/otel/sdk/trace` drops an attribute, event, or link
due to a limit being reached. (#5434)
- Document instrument name requirements in
`go.opentelemetry.io/otel/metric`. (#5435)
- Prevent random number generation data-race for experimental rand
exemplars in `go.opentelemetry.io/otel/sdk/metric`. (#5456)
- Fix counting number of dropped attributes of `Record` in
`go.opentelemetry.io/otel/sdk/log`. (#5464)
- Fix panic in baggage creation when a member contains `0x80` char in
key or value. (#5494)
- Correct comments for the priority of the `WithEndpoint` and
`WithEndpointURL` options and their corresponding environment variables
in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#5508)
- Retry trace and span ID generation if it generated an invalid one in
`go.opentelemetry.io/otel/sdk/trace`. (#5514)
- Fix stale timestamps reported by the last-value aggregation. (#5517)
- Indicate the `Exporter` in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` must be
created by the `New` method. (#5521)
- Improved performance in all `{Bool,Int64,Float64,String}SliceValue`
functions of `go.opentelemetry.io/attributes` by reducing the number of
allocations. (#5549)

Towards https://github.com/open-telemetry/opentelemetry-go/issues/5065
Follow our own docs. From `Processor.Enabled` docs:
> Before modifying a Record, the implementation must use Record.Clone to
create a copy that shares no state with the original.
I was looking at the trace benchmarks, and noticed this one, which says
it tests "span start", but ending the span is included within the data.
So this change removes ending the span from the computation, and adds a
new benchmark which only computes span end.
benchstat for span start:
```
pkg: go.opentelemetry.io/otel/sdk/trace
│ bench-main │ bench-branch │
│ sec/op │ sec/op vs base │
TraceStart-10 725.6n ± 3% 667.2n ± 2% -8.04% (p=0.000 n=10)
│ bench-main │ bench-branch │
│ B/op │ B/op vs base │
TraceStart-10 704.0 ± 0% 704.0 ± 0% ~ (p=1.000 n=10) ¹
¹ all samples are equal
│ bench-main │ bench-branch │
│ allocs/op │ allocs/op vs base │
TraceStart-10 14.00 ± 0% 14.00 ± 0% ~ (p=1.000 n=10) ¹
¹ all samples are equal
```
Benchmark for span end:
```
BenchmarkSpanEnd-10 16486819 147.7 ns/op 0 B/op 0 allocs/op
```
Part of #5056
It abstracts the `transform` package from `otlploghttp` and makes it a
shared template. Then, it generates the abstracted `transform` package
into `otlploggrpc`.

This adds a benchmark to create a logger from a logger provider.
Related: #5054.
```
BenchmarkLoggerProviderLogger-10 3145390 548.8 ns/op 330 B/op 1 allocs/op
```
This benchmark currently tests two rather different methods within the
same loop, which makes it hard to see what could be causing a
performance degradation.
Related: #5054.
```
BenchmarkSetAddAttributes/SetAttributes-10 14066331 82.80 ns/op 48 B/op 1 allocs/op
BenchmarkSetAddAttributes/AddAttributes-10 19333711 114.7 ns/op 0 B/op 0 allocs/op
```
- Added `WithHeaders` option func, which allows user to set custom http
request headers while exporting spans.
- Closes: #3474

As discussed in a previous SIG meeting, this PR adds support for setting
a default value for
[`service.instance.id`](https://github.com/open-telemetry/semantic-conventions/tree/main/docs/resource#service-experimental)
according to semantic conventions:
> Implementations, such as SDKs, are recommended to generate a random
Version 1 or Version 4 [RFC 4122](https://www.ietf.org/rfc/rfc4122.txt)
UUID, but are free to use an inherent unique ID as the source of this
value if stability is desirable. In that case, the ID SHOULD be used as
source of a UUID Version 5 and SHOULD use the following UUID as the
namespace: `4d63009a-8d0f-11ee-aad7-4c796ed8e320`.
This PR follows the recommendation and populates `service.instance.id`
with a random Version 4 UUID. The functionality is guarded by the
`OTEL_GO_X_RESOURCE` feature flag environment variable.
There are plans to declare `service.instance.id` stable and also make it
a required attribute (similar to `service.name`). Once this happens, the
functionality can be made available regardless of whether
`OTEL_GO_X_RESOURCE` is set.

The validation rule for baggage key/values chars has a N+1 problem with
the unicode value: `0x80`.
For instance, `baggage.NewMemberRaw` could be called with a string value
including the rune `128` and return no error.
Then `baggage.New` would panic on `validateValueChar`:
```
=== RUN TestValidateValueChar
--- FAIL: TestValidateValueChar (0.00s)
panic: runtime error: index out of range [128] with length 128 [recovered]
panic: runtime error: index out of range [128] with length 128
