Version 1.9.0

This release streams TestClient response bodies, so client.stream() returns before the application finishes. It also escapes path delimiters when building URLs, matches host names case-insensitively, and keeps every existing Vary header.

Changed

• Stream TestClient response bodies, so client.stream() returns before the application finishes. Closing an unfinished streamed response now cancels the application #3491.

Fixed

• Percent-encode ?, #, \ and a leading // in the request path when building request.url, and \ and a leading // in url_path_for #3671.
• Use the byte length for Content-Length when the response body is a typed or multidimensional memoryview #3622.
• Include HEAD in the Allow header of HTTPEndpoint 405 responses when GET is defined #3585.
• Match host names case-insensitively in Host routing and TrustedHostMiddleware #3542.
• Preserve every existing Vary header in MutableHeaders.add_vary_header(), used by GZipMiddleware and SessionMiddleware #3675.
