Default News Download Output is NOT changing to Epub3 from Epub2

snji · 04-19-2021, 03:29 AM

Hi,
I did try to search for the solution but could not find anything relevant. If this post is a duplicate, please let me know.

I am using Calibre 5.16.1 on Windows 10.

I have changed the default Epub Output to 3. [Preferences - Conversion - Output Options - Epub output - EPUB Version = 3 (default 2)]

But, Epub generated by Scheduled News Download is still creating Epub2 files.

To check that - I am opening the Containing Folder and looking at ".opf" file.

IF I edit the Epub in Calibre & use Tools - Upgrade Book Internals, then the book is modified to Epub3. But the associated ".opf" file is NOT updated.

I also looked into Job Details & there is a Flag " 'epub_version': '2'". But I don't know how to change this permanently.

Questions:
1. How to permanently fix output in Epub3?
2. How to easily see the actual epub file version (specially when .opf file doesn't match with epub file info) ?

Please help. Thanks.

ps: Thank You Covid for one of the best product for e-books.

I dont think news download respects that setting. In fact as far as I know there is nothing in news download that needs epub 3 so why do you want to change it?

"why do you want to change it?"

Sorry, no big reason or anything like that. I just recenly learnt about Epub3 and was tweaking things here and there in Calibre and stumbled on this.

If you have not implemented Epub3 for News Download, that's cool, You are the expert.

Once again, Thank You for creating an excellent software.

And I am really sorry for getting your name wrong in the post above. Infact, I was worried about it and went to your site to check the spelling, but damn ...
