I am pleased to announce the release of GNU Ocrad 0.28.

GNU Ocrad is an OCR (Optical Character Recognition) program and library 
based on a feature extraction method. It reads images in png or pnm formats 
and produces text in byte (8-bit) or UTF-8 formats.

Ocrad includes a layout analyser able to separate the columns and blocks of 
text normally found on printed pages.

Ocrad can be used as a stand-alone console application, or as a backend to 
other programs.

Key fingerprint = 1D41 C14B 272A 2219 A739  FA4F 8FE9 9503 132D 7742

Changes in version 0.28:

   * Support for PNG images has been implemented using libpng.

   * The variables AR and ARFLAGS can now be set from configure. (Before you 
needed to run 'make AR=<ar_command>'.

   * The version test macro 'OCRAD_API_VERSION' and the function 
'OCRAD_api_version' are now declared in the header file 'ocradlib.h'. They 
tell to the application the version of the library.

   * Many minor fixes and improvements have been made.
