A new version of Bengali Tesseract trained data has been released on Nov 29, 2016. This needs to be updated for Bengali Wikisource.
Previously it was done by @Tpt (vide T117711) and @Phe.
@Bodhisattwa: Sorry this task has not received a reply yet. So this seems to be a followup to T67354 and T117711.
Hence I am adding the Toolforge project tag, so the developers are actually able to see this task in their projects.
Should be done. I am not able to make sure it's actually live.
