gImageReader 3.3.0 (Sep 26 2018):
This is the first stable release of the 3.3.x series. The main change compared to 3.2.99 is support for the script traineddatas which were introduced with tesseract 4.x.

As with previous releases, the Windows builds using tesseract 4 are still to be considered experimental.

For a full list of changes between 3.2.99 and 3.3.0, see the git commit log.

gImageReader 3.2.99 (Feb 24 2018)
This is the beta release for gImageReader 3.3.0. The main highlight is a much expanded hOCR editor, and many bug fixes. Consult the changelog below for details. Special thanks to @ZaMaZaN4iK and @SantosSi for their valuable contributions both in code and improvement ideas.

There are a number of incomplete translations, so this would be a great moment for interested people to update their translations. gImageReader now hosts its translations on Weblate, so translating is easier than ever!

Please report any issues you might find to ensure a polished 3.3.0 release.

As with previous releases, the Windows builds using tesseract 4 are to be considered experimental.

Binary packages for Linux are available for Ubuntu in the gImageReader-devel PPA and for Fedora in this COPR repository.

Attention Windows Users
Some anti-virus scanners might report that the setup exe contains a troyan. Such reports are most likely a false positives, see http://nsis.sourceforge.net/NSIS_False_Positives. (NSIS is the installation system used to build the Windows installer.) Unfortunately there is little I can do on my side to fix this.

Update for Windows Users
The previously uploaded version, which used the Qt4 libraries, appeared to crash on Windows 64bit systems, apparently due to a bug in Qt4. I've now switched to using Qt5 on Windows, which should hopefully fix the issues.
