Release 2025-Apr-01

- Bug Fix: Re-export `WithContext` at
`opentelemetry::trace::context::WithContext`
[#&#8203;2879](https://redirect.github.com/open-telemetry/opentelemetry-rust/pull/2879)
to restore backwards compatability
- The new path for `WithContext` and `FutureExt` are in
`opentelemetry::context` as they are independent of the trace signal.
Users should prefer this path.

Released 2025-Mar-21

- *Breaking* Moved `ExportError` trait from
`opentelemetry::trace::ExportError` to
`opentelemetry_sdk::export::ExportError`
- *Breaking* Moved `TraceError` enum from
`opentelemetry::trace::TraceError` to
`opentelemetry_sdk::trace::TraceError`
- *Breaking* Moved `TraceResult` type alias from
`opentelemetry::trace::TraceResult` to
`opentelemetry_sdk::trace::TraceResult`
- Bug Fix: `InstrumentationScope` implementation for `PartialEq` and
`Hash` fixed to include Attributes also.
- **Breaking changes for baggage users**:
[#&#8203;2717](https://redirect.github.com/open-telemetry/opentelemetry-rust/issues/2717)
    -   Changed value type of `Baggage` from `Value` to `StringValue`
- Updated `Baggage` constants to reflect latest standard
(`MAX_KEY_VALUE_PAIRS` - 180 -> 64, `MAX_BYTES_FOR_ONE_PAIR` - removed)
and increased insert performance see
#[2284](https://redirect.github.com/open-telemetry/opentelemetry-rust/pull/2284).
- Align `Baggage.remove()` signature with `.get()` to take the key as a
reference
- `Baggage` can't be retrieved from the `Context` directly anymore and
needs to be accessed via `context.baggage()`
- `with_baggage()` and `current_with_baggage()` override any existing
`Baggage` in the `Context`
- `Baggage` keys can't be empty and only allow ASCII visual chars,
except `"(),/:;<=>?@&#8203;[\]{}` (see [RFC7230, Section
3.2.6](https://datatracker.ietf.org/doc/html/rfc7230#section-3.2.6))
- `KeyValueMetadata` does not publicly expose its fields. This should be
transparent change to the users.
- Changed `Context` to use a stack to properly handle out of order
dropping of `ContextGuard`. This imposes a limit of `65535` nested
contexts on a single thread. See
#[2378](https://redirect.github.com/open-telemetry/opentelemetry-rust/pull/2284)
and
#[1887](https://redirect.github.com/open-telemetry/opentelemetry-rust/issues/1887).
- Added additional `name: Option<&str>` parameter to the `event_enabled`
method
on the `Logger` trait. This allows implementations (SDK, processor,
exporters)
to leverage this additional information to determine if an event is
enabled.
