In urllib.request, suffixes in no_proxy environment variable with leading dots could match related hostnames again (e.g. .b.c matches a.b.c). Patch by Milan Oberkirch.
The deprecation include manual creation of SSLSocket and certfile/keyfile (or similar) in ftplib, httplib, imaplib, smtplib, poplib and urllib. ssl.wrap_socket() is not marked as deprecated yet.
When the body object is a file, its size is no longer determined with fstat(), since that can report the wrong result (e.g. reading from a pipe). Instead, determine the size using seek(), or fall back to chunked encoding for unseekable files. Also, change the logic for detecting text files to check for TextIOBase inheritance, rather than inspecting the ?mode? attribute, which may not exist (e.g. BytesIO and StringIO). The Content-Length for text files is no longer determined ahead of time, because the original logic could have been wrong depending on the codec and newline translation settings. Patch by Demian Brecht and Rolf Krahl, with a few tweaks by me.
