3.05.0017 Feb 2017 11:05 minor feature: Made some fine tuning to the hOCR output. Added TSV as another optional output format. ABI break introduced in 3.04.00 with the AnalyseLayout() method. text2image tool - Enable all OpenType ligatures available in a font. This feature requires Pango 1.38 or newer. Training tools - Replaced asserts with tprintf() and exit(1). Cygwin compatibility. Improved multipage tiff processing. Improved the embedded pdf font (pdf.ttf). Enable selection of OCR engine mode from command line. Changed tesseract command line parameter '-psm' to '--psm'. Added new C API for orientation and script detection, removed the old one. Increased minimum autoconf version to 2.59. Removed dead code. many compiler warning. memory and resource leaks. some with the 'Cube' OCR engine. some openCL. Added option to build Tesseract with CMake build system. Implemented CPPAN support for easy Windows building. . Added TSV as another optional output format.

Update README.md. Update README.md. Replace pdf.ttf with sharp2.ttf, keep name the same. Document hocr_font_info in config. INCOMPATIBLE to hOCR line height information -. varsize array for Microsoft compiler. Only generate dir for HOCR when needed -. Emit fewer "lang" attributes. Add LTR mixed direction test files. Update README.md. compiler warning (signed / unsigned mismatch). Adds char GetHOCRTSVText(int) as placeholder. Copy of char GetHOCRT?. Adds TessHOcrTsvRenderer class for rendering HOCR info in tsv format. Calls TessHOcrTsvRenderer if tessedit_create_hocrtsv is true. Adds hocrtsv file to configs folder.

3.04.0117 Feb 2016 10:45 minor feature: Add check for opencl requirements. Rework opencl requirements (configure: error: conditional "AMDEP"?. Typo. GRAPHICS_DISABLED build. Strcasestr needed on Cygwin too. Libicui18n is only called libicuin on mingw, not cygwin. Implement build without cube (-DNO_CUBE_BUILD). Tessedit_create_txt 0 blocks box training. Memmory leak based on (https://code.google.com/p/tesse?. Remove empty header file secname.h. Replace CubeUtils::UTF8ToUTF32 in pdfrenderer. Enable pdfrender with NO_CUBE_BUILD. NO_CUBE_BUILD with reverting to ANDROID_BUILD in baseapi. Improve NO_CUBE_BUILD. in UTF-16BE conversion. Remove extraneous line feed. VC14 compiler. Enable OpenMP support.

For OpenCL reported on Apple Mac. Still get -54 on Apple?. VS2010 build. OpenCL build on Mac. Configure.ac for OS X and -framework. Missing "allheaders.h" when compiling with --enable-opencl on OS X. Various clang compilation errors. Get OpenCL to compile on OS X. Configure.ac unconditionally enabling OpenCL. Add ULL to constants which overflow 32 bits. Simplify build and run of ScrollView. Tesstrain.sh: Only fall back to default Latin fonts if none were prov?. Tesstrain.sh: Only set FONTS if they weren't set on the command line. Tesstrain.sh: Initialise fontconfig even if Arial isn't available. Remove --bin_dir option from tesstrain.sh (should use PATH instead). Add --exposures option to tesstrain.sh. Use mktemp to create workspace directory. COPYING: typo found by codespell. Api: typos in comments (all found by codespell). Ccmain: typos in comments and strings. Typo.

3.04.01dev25 Aug 2015 03:45 minor feature: Added OpenCL support (experimental). Many.
3.04.0020 Aug 2015 08:26 minor feature: Tesseract development is now done with git and hosted at github.com (Previously we used Subversion as a vcs and code.google.com for hosting). Tesseract now requires leptonica 1.71 or a higher version. Removed official support for VS 2008. Added support for many more scripts/languages. Major updates to training system as a result of extensive testing on 100 languages. Improved performance with PIC compilation option. Significant change to invisible font system in pdf output to improve correctness and compatibility with external programs, particularly ghostscript. Improved font identification. Major change to improve layout analysis for heavily diacritic languages: Thai, Vietnamese, Kannada, Telugu etc. Fixed problems with shifted baselines so recognition can recover from layout analysis errors. Major refactor to improve speed on difficult images, especially when running a heap checker. Moved params from global in page layout to tesseractclass. Improved single column layout analysis. Allow ocr output to multiple formats using tesseract command line executable. Fixed issues with mixed eng+ara scripts. Improved script consistency in numbers. Major refactor of control.cpp to enable line recognition. Added tesstrain.sh - a master training script. Added ability to text2image training tool to just list available fonts. Added ability to text2image to underline words. Improved efficiency of image processing for PDF output. Added parameter description for each paramater listed with 'print-parameters' command line option. Added font info to hocr output. Enabled streaming input and output of multi-page documents. Many bug fixes.
