### Attention
Before you submit an issue, please review [the guidelines for this repository](https://github.com/tesseract-ocr/tesseract/blob/main/CONTRIBUTING.md).
Have a question? Need help?
Please use [our forum](https://groups.google.com/g/tesseract-ocr).
Please follow these rules:
* Don't open an issue for [Tesseract version which was released more than a year ago](https://tesseract-ocr.github.io/tessdoc/ReleaseNotes.html).
* Don't open an issue which involves 3rd party tools that use Tesseract as a library. Only report about an issue with the Tesseract command line tool or the C/C++ API.
* Please provide the input image.
* Also provide output files (txt and/or tsv, hocr, pdf). You can make a zip archive that will contain these files, so GitHub will let you upload them.
* Don't attach a screenshot of the command line and output. Instead, copy the text and paste it in your bug report.
Windows versions 7, 8, 8.1 are not supported.

2023-10-05 - V5.3.3
* Small code fixes and improvements to fix Coverity Scan issues.
* Disable -mfpu=neon for aarch64.
* Fix build without git clone in cloned directory (required for FreeBSD).
* Other build fixes for autotools, cmake and sw.
* Fix regression in layout detection which was introduced in release 5.0.0.
* Fix regression which prevented loading of submodels, introduced in release 5.0.0-rc2.
* Other small improvements for code and documentation.
2023-07-11 - V5.3.2
* Updates for snap package building.
* Support for Sgaw and W Pwo Karen languages in the Myanmar validator (#4065).
@ -264,7 +273,7 @@
* Many other fixes, including the way in which the chopper finds chops and messes with the outline while it does so.
2010-11-29 - V3.01
* Removed old/dead serialise/deserialze methods on *LISTIZED classes.
* Removed old/dead serialise/deserialize 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 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.
