Version 3.0

Table of Contents viewer — A new ToC tab lets you explore the full Table of Contents structure of any EPUB in your library, including node depth and link targets. Export the ToC to a text file or copy it to the clipboard; right-click any node to copy its title, target, or subtree.

New ToC-based book scanner — A new scanner finds EPUBs by their ToC node count. Set an operator (≤ or ≥) and a threshold to locate books with sparse or overly complex Tables of Contents. Useful for spotting EPUBs with missing or broken navigation.

--

Version 3.1

Orphan HTML scanner — A new scanner detects EPUBs with content files not referenced in the Table of Contents — pages that readers will never reach via navigation. Matching books are marked in the library for easy review, with a detailed log viewer showing exactly which files are orphaned in each book. Accessible via the EPUB ToC scanner submenu.

Yes, yes it works. 2 books upgrade from epub1 to epub2 and Calibre Check book shows all is OK. Thank you. Will wait to see curent opf and changed opf.

Oh, you changed only version="1.0" to version="2.0". Is it enough?

OPF Helper shows "No schema available for version", Calibre editor shows epub1.

Gotta love it when folk make up their own designations or 'fix an error' .
In many cases the first version number is implied.
EPUB, EPUB2, EPUB3

You could try and change the package version= from "1.0" to "2.0" in the BOOKS OPF using the editor

The calibre Editor can upgrade book internals on per book basis. Later I'll look more into this. But it will update from 2.0 to 3.0. You are targetting 2.0, so you must have reason for this..

I thought you just needed a bulk operation 1 to 2.

Now I suggest you try the calibre Polish tool, see: (just press P)

There is no ePub1. What we had before ePub2 was Open eBook Publication Structure. This is what LIT was using.

Unlike these earlier formats, EPUB offers greater flexibility.

It was created by the International Digital Publishing Forum in 2007 as a successor format to the Open eBook Publication Structure (OEB), an early XML-based eBook format. EPUB 2.0 officially replaced OEB in 2007. EPUB3, introduced in 2011, brought HTML5 support along with multimedia and accessibility improvements.
