[Announcement] Release 1.7.0

[Tyler Hobbs]

I just put the 1.7.0 tarball up on github and pypi.

This is not necessarily a drop-in upgrade, mostly due to timezone changes for datetime objects.  Read the changelog for full details.

If you encounter any problems, please open a ticket here: https://github.com/pycassa/pycassa/issues

You can read the nice version of the changelog here: http://pycassa.github.com/pycassa/changelog.html#changes-in-version-1-7-0
A plain-text version follows:

Changes in Version 1.7.0
===================

    This release has a few relatively large changes in it: a new connection
    pool stats collector, compatibility with Cassandra 0.7 through 1.1, and a
    change in timezone behavior for datetimes.

    Before upgrading, take special care to make sure datetimes that you pass to
    pycassa (for TimeUUIDType or DateType data) are in UTC, and make sure your code
    expects to get UTC datetimes back in return.

    Likewise, the SystemManager changes should be backwards compatible, but there
    may be minor differences, mostly in create_column_family() and
    alter_column_family(). Be sure to test any code that works programmatically
    with these.

    Features

      * Added StatsLogger for tracking ConnectionPool metrics
      * Full Cassandra 1.1 compatibility in SystemManager. To support this, all
        column family or keyspace attributes that have existed since Cassandra 0.7 may
        be used as keyword arguments for create_column_family() and
        alter_column_family(). It is up to the user to know which attributes are
        available and valid for their version of Cassandra. As part of this change, the
        version-specific thrift-generated cassandra modules (pycassa.cassandra.c07,
        pycassa.cassandra.c08, and pycassa.cassandra.c10) have been replaced by
        pycassa.cassandra. A minor related change is that individual connections now
        now longer ask for the node’s API version, and that information is no longer
        stored as an attribute of the ConnectionWrapper.

    Bug Fixes

      * Fix xget() paging for non-string comparators
      * Add batch_insert() to ColumnFamilyMap
      * Use setattr instead of directly updating the object’s __dict__ in
      * ColumnFamilyMap to avoid breaking descriptors
      * Fix single-column counter increments with ColumnFamily.insert()
      * Include AuthenticationException and AuthorizationException in the pycassa module
      * Support counters in xget()
      * Sort column families in pycassaShell for display
      * Raise TypeError when bad keyword arguments are used when creating a ColumnFamily object

    Other

        All datetime objects create by pycassa now use UTC as their timezone
        rather than the local timezone. Likewise, naive datetime objects that
        are passed to pycassa are now assumed to be in UTC time, but tz_info is
        respected if set.

        Specifically, the types of data that you may need to make adjustments
        for when upgrading are TimeUUIDType and DateType (including OldPycassaDateType
        and IntermediateDateType).
