Doubt about using 5.0.0-beta-20210916 before release version is available

[juan carlos hernández]

Hello

I'm working in a project that needs OCR and we have choosed to use Tesseract. We would like to use v5.0.0, but our IT Infrastructure team doesn't want to install it because it is a beta version. I've read in another conversation (https://groups.google.com/g/tesseract-dev/c/Js2Hy22d1B0) that version 5.0.0 can be considered stable. We are going to use tesseract from scratch, so we don't have any problem with backward compatibility. 

Please can you confirm that version  5.0.0-beta-20210916 can be installed in production environments? 

In any case, do you have a planned date for the 5.0.0 release?

Thanks in advance

I would say that you can. At archive.org we've been running millions
(literally) of documents through Tesseract 5.0 alpha and beta:

Yes. Speed and stability is better, and accuracy is also up (IMHO). See
(for example) this link:

Hi

Many thanks for your answers. 

I've checked pending milestones of v 5.0.0 (https://github.com/tesseract-ocr/tesseract/milestone/6), and from the 17 pending ones, I see that some of them come from v4, and others are related to training or languages different from english or spanish, . 

So the only issues that could really affect my project are these ones:

https://github.com/tesseract-ocr/tesseract/issues/3109

https://github.com/tesseract-ocr/tesseract/issues/3473

These two issues are only related to performance. As v5 runs 3 or 4 times faster in my tests, I don't see any reason for not using current beta version in production environments. We also have the experience that the archive.org project has had with v5, which is very positive.

I think I can try to convince my IT infraestructure team with these arguments. In any case I think I can also wait for the release of 5.0.0 if it doesn´t take months to be delivered.

Regards

Juan Carlos
