Pypdf3

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

- NOTE: Active maintenance on PyPDF2 is resuming after a hiatus

- Fixed a bug where image resources where incorrectly
overwritten when merging pages

- Added dictionary for JavaScript actions to the root (louib)

- Added unit tests for the JS functionality (louib)

- Add more Python 3 compatibility when reading inline images (im2703
and (VyacheslavHashov)

- Return NullObject instead of raising error when failing to resolve
object (ctate)

- Don't output warning for non-zeroed xref table when strict=False
(BenRussert)

- Remove extraneous zeroes from output formatting (speedplane)

- Fix bug where reading an inline image would cut off prematurely
in certain cases (speedplane)


Patch 1.25.1, 2015-07-20

- Fix bug when parsing inline images. Occurred when merging
certain pages with inline images

- Fixed type error when creating outlines by utilizing the
isString() test

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

BUGFIXES:

- Added Python 3 algorithm for ASCII85Decode. Fixes issue when
reading reportlab-generated files with Py 3 (jerickbixly)

- Recognize more escape sequence which would otherwise throw an
exception (manuelzs, robertsoakes)

- Fixed overflow error in generic.py. Occurred
when reading a too-large int in Python 2 (by Raja Jamwal)

- Allow access to files which were encrypted with an empty
password. Previously threw a "File has not been decrypted"
exception (Elena Williams)

- Do not attempt to decode an empty data stream. Previously
would cause an error in decode algorithms (vladir)

- Fixed some type issues specific to Py 2 or Py 3

- Fix issue when stream data begins with whitespace (soloma83)

- Recognize abbreviated filter names (AlmightyOatmeal and
Matthew Weiss)

- Copy decryption key from PdfFileReader to PdfFileMerger.
Allows usage of PdfFileMerger with encrypted files (twolfson)

- Fixed bug which occurred when a NameObject is present at end
of a file stream. Threw a "Stream has ended unexpectedly"
exception (speedplane)

FEATURES:

- Initial work on a test suite; to be expanded in future.
Tests and Resources directory added, README updated (robertsoakes)

- Added document cloning methods to PdfFileWriter:
appendPagesFromReader, cloneReaderDocumentRoot, and
cloneDocumentFromReader. See official documentation (robertsoakes)

- Added method for writing to form fields: updatePageFormFieldValues.
This will be enhanced in the future. See official documentation
(robertsoakes)

- New addAttachment method. See documentation. Support for adding
and extracting embedded files to be enhanced in the future
(moshekaplan)

- Added methods to get page number of given PageObject or
Destination: getPageNumber and getDestinationPageNumber.
See documentation (mozbugbox)

OTHER ENHANCEMENTS:

- Enhanced type handling (Brent Amrhein)

- Enhanced exception handling in NameObject (sbywater)

- Enhanced extractText method output (peircej)

- Better exception handling

- Enhanced regex usage in NameObject class (speedplane)
