- `OtelPathNames` extension to provide known parameterized paths that will be used in span names

### Changed
- `DefaultSpanBackend` and `SpanBackendWithUrl` default span name to HTTP method name instead of `reqwest-http-client`

## [0.4.1] - 2023-03-09

### Added

- Support for `wasm32-unknown-unknown` target

## [0.4.0] - 2022-11-15

### Changed
- Updated `reqwest-middleware` to `0.2.0`
- Before, `root_span!`/`DefaultSpanBacked` would name your spans `{METHOD} {PATH}`. Since this can be quite
  high cardinality, this was changed and now the macro requires an explicit otel name.
  `DefaultSpanBacked`/`SpanBackendWithUrl` will default to `reqwest-http-client` but this can be configured
  using the `OtelName` Request Initialiser.

### Added
- `SpanBackendWithUrl` for capturing `http.url` in traces
- `OtelName` Request Initialiser Extension for configuring
