documentation: fix ssl typos in the changelog
* Fixed a bug where some encodings (like utf-16) were unusable on Python 3
as command names and literals would get encoded.
* Added an SSLConnection class that allows for secure connections through
- stunnel or other means. Construct and SSL connection with the sll=True
+ stunnel or other means. Construct an SSL connection with the ssl=True
option on client classes, using the rediss:// scheme from an URL, or
by passing the SSLConnection class to a connection pool's
connection_class argument. Thanks https://github.com/oranagra.
