I'm in the process of converting all my .mobi (
deprecated by Amazon in late 2023) and .azw3 (
Amazon discontinued it in 2022) to
open file format standards like PDF and EBUB. So I researched little-bit about them...
Noticed that now we've PDF 2.0,
ISO 32000-2 does not include any proprietary technologies and available for free. (reference:
https://pdfa.org/sponsored-standards)
I wonder why Calibre still use old PDF v1.4 for conversion? Calibre developers unaware of this or they use it for specific purpose?
I'm not sure what are the benefits of using latest PDF standard (technical aspects) but like any other technology I assume it has some improvements and stability over older editions?
ThankYou
