Dear MySQL users,
MySQL Connector/Python 2.2.1 M2 is the second development release of the
MySQL Connector Python 2.2 series. This series adds support for the new
X DevAPI. The X DevAPI enables application developers to write code that
combines the strengths of the relational and document models using a
modern, NoSQL-like syntax that does not assume previous experience
writing traditional SQL.
To learn more about how to write applications using the X DevAPI, see
http://dev.mysql.com/doc/x-devapi-userguide/en/. For more information
about how the X DevAPI is implemented in MySQL Connector/Python, and its
usage, see
http://dev.mysql.com/doc/dev/connector-python.
Please note that the X DevAPI requires at least MySQL Server version
5.7.12 or higher with the X Plugin enabled. For general documentation
about how to get started using MySQL as a document store, see
http://dev.mysql.com/doc/refman/5.7/en/document-store.html.

Changes in MySQL Connector/Python 2.2.1 (2016-09-13)
MySQL Connector/Python 2.2.1 has a prerequisite of Protobuf
3, and is available in a more limited number of distribution
formats than usual (RPM and tar.gz packages only).
* X DevAPI Notes
* Functionality Added or Changed
* Bugs Fixed
X DevAPI Notes
* Views can now be accessed like tables:
+ Schema.get_tables() now also returns a Table object
for each existing View.
+ Schema.get_table(name) now also returns a Table
object if the given name is a View.
+ All the operations available through a Table object
are also available if the underlying object is a
View. (The client will not do any validation in this
regard.)
+ A new Table.is_view() method determines whether the
underlying object is a View.
* The Collection.add([]).execute() construct now is treated
as a no-operation and does not return an error. This is
true even if there is no connection to the server or the
collection does not exist on the server. The reasoning is
that a request to add nothing to something that does not
exist is trivially fulfilled.
* Connector/Python now implements support for these X
DevAPI features:
+ Client failover
+ URI connection format
Functionality Added or Changed
* Protobuf support was upgraded from Protobuf 2 to Protobuf
3 (which means that Protobuf3 is now a prerequsite for
Connector/Python).
Bugs Fixed
* Attempts to fetch a value having the BIT data type
produced an error. (Bug #23729357)
* The fetchone() result set method and close() session
method were missing. They are now included. (Bug
#23568257, Bug #23550743)
* Session creating using a URL-format connection string
failed. (Bug #23550057)
