Fix connecting to link-local IPv6 addresses. #4554
Fix a problem with connection waiters that are never awaited. #4562
Always make sure transport is not closing before reuse a connection.
Reuse a protocol based on keepalive in headers is unreliable. For example, uWSGI will not support keepalive even it serves a HTTP 1.1 request, except explicitly configure uWSGI with a
--http-keepalive
option.Servers designed like uWSGI could cause aiohttp intermittently raise a ConnectionResetException when the protocol poll runs out and some protocol is reused. #4587
Handle the last CRLF correctly even if it is received via separate TCP segment. #4630

This behavior should prevent clients from being unable to use PUT/POST methods on endpoints that are redirected because of a trailing slash. #3579
Drop the processed task from
all_tasks()
list early. It prevents logging about a task with unhandled exception when the server is used in conjunction withasyncio.run()

to work with I/O objects asynchronously. #3313- Internal Server Errors in plain text if the browser does not support HTML. #3483
- Preserve MultipartWriter parts headers on write. Refactor the way how
