### Motivation

On main, the HTTPBody length type changed from Int to Int64.

### Modifications

Adapted the transport with this change.

### Result

Repo builds again when using the latest runtime.

### Test Plan

Adapted tests.

### Motivation

Part of addressing
apple/swift-openapi-generator#75 and
apple/swift-openapi-generator#119.

### Modifications

Bumped Swift tools version to 5.9 and made the `ExistentialAny` build
setting unconditional.

### Result

Building the package requires 5.9 now.

### Test Plan

Ran tests, all passed when using a Swift 5.9 toolchain.

#34)

### Motivation

We had some code in an `#if swift(<5.9)` block, which can now be removed
because we only support Swift 5.9 and newer.

### Modifications

Remove code required to support Swift 5.8.

### Result

Removed dead code.

### Test Plan

Tests pass.

### Motivation

The tests had a missing `@available` annotation which meant that they
didn't build iOS (annoyingly, when building for macOS, these things are
not checked so things were building fine locally).

### Modifications

Add missing available annotation to streaming tests.

### Result

Builds for iOS again.

### Test Plan

Local testing, selecting generic iOS destination in Xcode. This failed
before this patch, and succeeds with it.

### Motivation

While this isn't technically necessary, as all versions of a platform
not explicitly mentioned are assumed to be supported, it's better to be
explicit here.

### Modifications

Add `visionOS(.v1)` to the list of supported platforms.

### Result

Clearer support matrix.

### Test Plan

N/A, this is basically just a documentation change.

See apple/swift-openapi-generator#396.

### Motivation

Recent SwiftPM versions seem to be a bit stricter about using (i.e.,
`import ...`) transitive dependencies without explicitly declaring them
as direct dependencies.

### Modifications

Explicitly depend on the HTTPTypes module from swift-http-types.

### Result

More explicitly declare the dependency graph.

### Test Plan

All tests pass.

### Motivation

Ready the docs for 1.0.

### Modifications

Updated README.md and documentation, updated the runtime dependency.

### Result

Ready for 1.0.

### Test Plan

Reviewed locally.

### Motivation

In our fallback, buffered implementation, we did not use a task
cancellation handler so were not proactively cancelling the URLSession
task when the Swift concurrency task was cancelled. Additionally, while
we _did_ have a task cancellation handler in the streaming
implementation, so the URLSession task would be cancelled, we were not
actively checking for task cancellation as often as we could.

### Modifications

- Added more cooperative task cancellation.
- Added tests for both implementations that when the parent task for the
client request is cancelled that we get something sensible. Note that in
some cases, the request will succeed. In the cases where the request
fails, it will surface as a `ClientError` to the user where the
`underlyingError` is either `Swift.CancellationError` or `URLError` with
`code == .cancelled`.

### Result

More cooperative task and URLSession task cancellation and more thorough
tests.

### Test Plan

Added unit tests.
