Version 1.6, 2006-06-06
-----------------------

 - Add basic support for comments in PDF files.  This allows us to read some
   ReportLab PDFs that could not be read before.

 - Add "auto-repair" for finding xref table at slightly bad locations.

 - New StreamObject backend, cleaner and more powerful.  Allows the use of
   stream filters more easily, including compressed streams.

 - Add a graphics state push/pop around page merges.  Improves quality of
   page merges when one page's content stream leaves the graphics 
   in an abnormal state.

 - Add PageObject.compressContentStreams function, which filters all content
   streams and compresses them.  This will reduce the size of PDF pages,
   especially after they could have been decompressed in a mergePage
   operation.

 - Support inline images in PDF content streams.

 - Add support for using .NET framework compression when zlib is not
   available.  This does not make pyPdf compatible with IronPython, but it
   is a first step.

 - Add support for reading the document information dictionary, and extracting
   title, author, subject, producer and creator tags.

 - Add patch to support NullObject and multiple xref streams, from Bradley
   Lawrence.


Version 1.5, 2006-01-28
-----------------------

- Fix a bug where merging pages did not work in "no-rename" cases when the
  second page has an array of content streams.

- Remove some debugging output that should not have been present.


Version 1.4, 2006-01-27
-----------------------

- Add capability to merge pages from multiple PDF files into a single page
  using the PageObject.mergePage function.  See example code (README or web
  site) for more information.

- Add ability to modify a page's MediaBox, CropBox, BleedBox, TrimBox, and
  ArtBox properties through PageObject.  See example code (README or web site)
  for more information.

- Refactor pdf.py into multiple files: generic.py (contains objects like
  NameObject, DictionaryObject), filters.py (contains filter code),
  utils.py (various).  This does not affect importing PdfFileReader
  or PdfFileWriter.

- Add new decoding functions for standard PDF filters ASCIIHexDecode and
  ASCII85Decode.

- Change url and download_url to refer to new pybrary.net web site.


Version 1.3, 2006-01-23
-----------------------

- Fix new bug introduced in 1.2 where PDF files with \r line endings did not
  work properly anymore.  A new test suite developed with various PDF files
  should prevent regression bugs from now on.

- Fix a bug where inheriting attributes from page nodes did not work.


Version 1.2, 2006-01-23
-----------------------

- Improved support for files with CRLF-based line endings, fixing a common
  reported problem stating "assertion error: assert line == "%%EOF"".

- Software author/maintainer is now officially a proud married person, which
  is sure to result in better software... somehow.


Version 1.1, 2006-01-18
-----------------------

- Add capability to rotate pages.

- Improved PDF reading support to properly manage inherited attributes from
  /Type=/Pages nodes.  This means that page groups that are rotated or have
  different media boxes or whatever will now work properly.

- Added PDF 1.5 support.  Namely cross-reference streams and object streams.
  This release can mangle Adobe's PDFReference16.pdf successfully.


Version 1.0, 2006-01-17
-----------------------

- First distutils-capable true public release.  Supports a wide variety of PDF
  files that I found sitting around on my system.

- Does not support some PDF 1.5 features, such as object streams,
  cross-reference streams.
