* 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.

* Removed old/dead serialise/deserialze methods on *LISTIZED classes.
* Total rewrite of DENORM to better encapsulate operation and make
for potential to extract features from images.
* Thread-safety! Moved all critical globals and statics to members of the appropriate class. Tesseract is now thread-safe (multiple instances can be used in parallel in multiple threads.) with the minor exception that some control parameters are still global and affect all threads.
* Thread-safety! Moved all critical global and static variables to members of the appropriate class. Tesseract is now thread-safe (multiple instances can be used in parallel in multiple threads.) with the minor exception that some control parameters are still global and affect all threads.
* Added Cube, a new recognizer for Arabic. Cube can also be used in combination with normal Tesseract for other languages with an improvement in accuracy at the cost of (much) lower speed. *There is no training module for Cube yet.*
* `OcrEngineMode` in `Init` replaces `AccuracyVSpeed` to control cube.
* Greatly improved segmentation search with consequent accuracy and speed improvements, especially for Chinese.
