Converting from Epub vs ORIGINAL_EPUB
I'm running Calibre 8.8 right now. I had an unusual conversion happening where it kept using the ORIGINAL_EPUB file to convert from and not the existing EPUB format.
After I removed the ORIGINAL_EPUB file, it converted correctly. Just wanted to post this before I forget it ever happened. This seems like a bug. I'm updating to 8.9 Calibre now. I'll double-check that 8.9 converts as expected. Thanks! |

Calibre will always use the ORIGINAL_EPUB file when reconverting.
See Release: 0.8.11 [22 Jul, 2011] New Features When doing a conversion from some format to the same format, save the original file
When calibre does a conversion from the same format to the same format, for example, from EPUB to EPUB, the original file is saved as original_epub, so that in case the conversion is poor, you can change the settings and run it again. The original is automatically used every time you run a conversion with that format as input. If you want to disable this, there is a tweak that prevents calibre from saving the originals in Preferences->Tweaks. You can easily replace the converted version with the original in the Edit metadata dialog by right clicking on the list of formats in the top right corner. |

FYI, all release notes going back forever (version 0.6 IIRC) are available in the calibre repository in the file Changelog.old.txt

Can we have an option to not automatically use ORIGINAL_EPUB and have it there as a safety backup?

I always have a copy outside of Calibre on the same computer, so I delete "ORIGINAL_EPUB". Everything is backed up.
