About new 2025 edition of Moomin books

I'd like to talk about Moomin books pocket-sized new edition of 2025.
There are already softcover new edition of 2019-2020.
And there are so many differences between this two new editions in the text.
For example, '子ネコ' in softcover is replaced to '子ねこ' in pocket-sized Commet in Moominland(Moomin Dani no Suisei).
And also "ガーネットが二つ" in softcover is replaced to "ガーネットがふたつ" in pocket-sized.
Such like these chages are uncountable. What is Kodansya's porpose with these changes?
I don't know, but I found two important changes in pocket-sized edition.
These are not only notational things, but related to the content of stories.
So we Moomin fans cannot ignore pocket-sized edition, and I must peruse all nine books one day near future.

I asked ChatGPT to rewrite my text into perfect natural English.

Revised Version by ChatGPT

I'd like to talk about the new 2025 pocket-sized edition of the Moomin books.
There was already a softcover new edition released between 2019 and 2020, but there are many differences in the text between that edition and the new pocket-sized one.

For example, the word "子ネコ" in the softcover edition is changed to "子ねこ" in the pocket-sized version of Comet in Moominland (Mūmindani no Suisei).
Similarly, "ガーネットが二つ" becomes "ガーネットがふたつ" in the newer edition.
These kinds of changes are countless.

What is Kodansha’s purpose in making these changes?
I'm not sure, but I did find two important differences in the pocket-sized edition that go beyond spelling or notation—they actually affect the content of the stories.

That’s why we Moomin fans can't ignore the pocket-sized edition.
I feel I must read through all nine books carefully sometime in the near future.
