Release v1.42.0/v0.64.0/v0.18.0/v0.0.16 (#8006)
a3941ff 
### Added

- Add `go.opentelemetry.io/otel/semconv/v1.40.0` package.
The package contains semantic conventions from the `v1.40.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.40.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.39.0`. (#7985)
- Add `Err` and `SetErr` on `Record` in `go.opentelemetry.io/otel/log`
to attach an error and set record exception attributes in
`go.opentelemetry.io/otel/log/sdk`. (#7924)

### Changed

- `TracerProvider.ForceFlush` in `go.opentelemetry.io/otel/sdk/trace`
joins errors together and continues iteration through SpanProcessors as
opposed to returning the first encountered error without attempting
exports on subsequent SpanProcessors. (#7856)

### Fixed

- Fix missing `request.GetBody` in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` to
correctly handle HTTP2 GOAWAY frame. (#7931)
- Fix semconv v1.39.0 generated metric helpers skipping required
attributes when extra attributes were empty. (#7964)
- Preserve W3C TraceFlags bitmask (including the random Trace ID flag)
during trace context extraction and injection in
`go.opentelemetry.io/otel/propagation`. (#7834)

### Removed

- Drop support for [Go 1.24]. (#7984)

@MrAlias Why drop support for go1.24. The reason is not clear, and maybe not that enough.
If using a lower version is OK, more old projects will benefit from your following updates.

See our compatibility policy: https://github.com/open-telemetry/opentelemetry-go?tab=readme-ov-file#compatibility
1.24 is not supported anymore. You won't get security fixes for it, you should upgrade.
