waitress 3.0.0

Waitress WSGI server

Waitress is a production-quality pure-Python WSGI server with very acceptable performance. It has no dependencies except ones which live in the Python standard library. It runs on CPython on Unix and Windows under Python 3.8+. It is also known to run on PyPy 3 (version 3.8 compatible python and above) on UNIX. It supports HTTP/1.0 and HTTP/1.1.

3.0.0 (2024-02-04)

• Rename “master” git branch to “main”

• Fix a bug that would appear on macOS whereby if we accept() a socket that is already gone, setting socket options would fail and take down the server. See https://github.com/Pylons/waitress/pull/399

• Fixed testing of vendored asyncore code to not rely on particular naming for errno’s. See https://github.com/Pylons/waitress/pull/397

• HTTP Request methods and versions are now validated to meet the HTTP standards thereby dropping invalid requests on the floor. See https://github.com/Pylons/waitress/pull/423

• No longer close the connection when sending a HEAD request response. See https://github.com/Pylons/waitress/pull/428

• Always attempt to send the Connection: close response header when we are going to close the connection to let the remote know in more instances. https://github.com/Pylons/waitress/pull/429
