- Prevent exception when reading a null object in decoding parameters

- Corrected error in reading destination types (added a slash since they
are name objects)

(provided by ian-su-sirca)

- Fixed bug caused by whitespace when parsing PDFs generated by AutoCad

- Fixed a bug caused by reading a 'null' ASCII value in a dictionary
object (primarily in PDFs generated by AutoCad).

FEATURES:
- Added new folders for PyPDF2 sample code and example PDFs; see README

since it has grown much since the original pyPdf

- A FAQ to answer common questions

------------------------

- Fixed a bug where older verions of objects were incorrectly added to the
cache, resulting in outdated or missing pages, images, and other objects
(from speedplane)

- Fixed a bug in parsing the xref table where new xref values were
overwritten; also cleaned up code (from speedplane)

- New method mergeRotatedAroundPointPage which merges a page while rotating
it around a point (from speedplane)

jamma313)

- PyPDF2 issue tracker enabled on Github to allow community
discussion and collaboration


Versions -1.16, -2013-06-30
---------------------------

- Note: This ChangeLog has not been kept up-to-date for a while.
Hopefully we can keep better track of it from now on. Some of the
changes listed here come from previous versions 1.14 and 1.15; they
were only vaguely defined. With the new _version.py file we should
have more structured and better documented versioning from now on.

- Defined PyPDF2.__version__

- Fixed encrypt() method (from Martijn The)

- Improved error handling on PDFs with truncated streams (from cecilkorik)

- Python 3 support (from kushal-kumaran)

- Fixed example code in README (from Jeremy Bethmont)

- Fixed an bug caused by DecimalError Exception (from Adam Morris)

- Many other bug fixes and features by:

jeansch
Anton Vlasenko
Joseph Walton
Jan Oliver Oelerich
Fabian Henze
And any others I missed.
