Update to version 2.20.1: * Fixed bug with unintended Authorization header stripping for redirects using default ports (http/80, https/443). Update to version 2.20.0: * Bugfixes + Content-Type header parsing is now case-insensitive (e.g. charset=utf8 v Charset=utf8). + Fixed exception leak where certain redirect urls would raise uncaught urllib3 exceptions. + Requests removes Authorization header from requests redirected from https to http on the same hostname. (CVE-2018-18074) + should_bypass_proxies now handles URIs without hostnames (e.g. files). Update to version 2.19.1: * Fixed issue where status_codes.py’s init function failed trying to append to a __doc__ value of None. Update to version 2.19.0: * Improvements + Warn about possible slowdown with cryptography version < 1.3.4 + Check host in proxy URL, before forwarding request to adapter. + Maintain fragments properly across redirects. (RFC7231 7.1.2) + Removed use of cgi module to expedite library load time. + Added support for SHA-256 and SHA-512 digest auth algorithms. + Minor performance improvement to Request.content. * Bugfixes + Parsing empty Link headers with parse_header_links() no longer return one bogus entry. + Fixed issue where loading the default certificate bundle from a zip archive would raise an IOError. + Fixed issue with unexpected ImportError on windows system which do not support winreg module. + DNS resolution in proxy bypass no longer includes the username and password in the request. This also fixes the issue of DNS queries failing on macOS. + Properly normalize adapter prefixes for url comparison. + Passing None as a file pointer to the files param no longer raises an exception. + Calling copy on a RequestsCookieJar will now preserve the cookie policy correctly. Update to version 2.18.4: * Improvements + Error messages for invalid headers now include the header name for easier debugging Update to version 2.18.3: * Improvements + Running $ python -m requests.help now includes the installed version of idna. * Bugfixes + Fixed issue where Requests would raise ConnectionError instead of SSLError when encountering SSL problems when using urllib3 v1.22. - Add ca-certificates (and ca-certificates-mozilla) to dependencies, otherwise https connections will fail.
