Hello all,

I am proud to announce new release of tesseract OCR engine - version 5.2.0:
  • Improvements and fixes for continuous integration, autoconf and cmake builds.
  • Set /Os for some 32 bit MS compilers (fixes #3769).
  • Improve comments and other documentation.
  • Add initial support for Intel AVX512F.
  • Fix for very large PDF files on 32 bit hosts (fixes #3805).
  • Fix NEON detection on FreeBSD.
  • Fix regression with UZN files (fixes #3837).
  • Fix calling delete[] for memory allocated by malloc in C API.
  • Add an API function to init tesseract with traineddata from memory (fixes #3691).
  • Replace direct access to Leptonica internal data structures by function calls and support latest releases of Leptonica.
  • Replace std::regex by std::string functions (fixes issue #3830).
  • Use compiled-in TESSDATA_PREFIX also on Windows (fixes #3767).
  • Add new parameter 'invert_threshold', change the default threshold from 0.5 to 0.7 and mark parameter 'tessedit_do_invert' as deprecated.
