Starting in 3.2, the logging module no longer outputs the following message when logging and no handlers are configured for the root logger:

    log = logging.getLogger()
    log.error('test')

'No handlers could be found for logger "root"'

However, I can't seem to find any version-changed about this in the docs.  The code change may be from this commit: c86dc2bd3ae8

Incidentally, I also noticed that three logging paragraphs begin with "PLEASE NOTE:"  Those should probably be changed to ".. note::" etc.

Although there is no versionadded directive, the HOWTO documentation does state that the behaviour relates to Python 3.2 and later, and how to obtain the earlier behaviour.

I will add documentation (including a versionadded) to the reference docs and also update the "PLEASE NOTE:" occurrences to use ".. note::" directives instead.

Thanks a lot, Vinay.  By the way, I noticed that the "PLEASE NOTE" reformatting can also be applied to 2.7.
