ebook-convert error: "no such option: --epub-version"
Pretty much what my title says..

Have some code that used to work fine. Upgraded Calibre to 7.23.0 and now when I run:

ebook-convert.exe "input_file_path" "output_file_path" <buncha options> --epub-version "3"

I now get the error:

ebook-convert.exe: error: no such option: --epub-version

Again, my code has not changed. And according to latest documentation here, https://manual.calibre-ebook.com/gen...k-convert.html , --epub-version is still a valid option.

Any ideas? Thanks.

It is still an option and works fine, you are probably running ebook-convert from an older calibre install. Check your PATH or use an absolute path to invoke the correct ebook-convert binary

Thank you! I thought I checked that PATH but must've had something stale in my shell. It is working now, thank you both!
