Perhaps I am attributing more conscious malice to Cochrane than they deserve and this was a purely administrative action to reflect the changes to the editors’ note on their abandoning the new review process. However it will cause the casual reader to misperceive this as a new current review, which can be very misleading especially as it may seem it has been updated since the pandemic and Long Covid.
Certainly if I am looking at references I always start with the most recent date.

I don't know what is standard practice at Cochrane but it does seem that previous editorial notes did not result in a new publication of the entire review. For example the previous note about the update in 2020, did not result in a new version.

Does anyone have access to the 2024 version?
Am I correct to think that the latest search of the literature took place in May 2014, so more than 10 years ago?

Is this what you meant or am I getting confused?
https://www.cochrane.org/CD003200/CENTRALED_exercise-treatment-adults-chronic-fatigue-syndrome
And even if they don’t intend it to be used that way it will allow citers to ‘choose’ which one they prefer

To clarify myself: I can see the abstract and summary of the 2024 version of the review but not the full text. I do not have access to download it. I was wondering if anyone else have access to check if it is indeed the same as the 2019 but with the editorial note added to it.
In the latest version (the 2019 version) I have access to, the latest literature search by the author team was conducted in may 2014. It says for example:
So any studies published after may 2014 were not included. The GETSET trial for example was not included in the review.
I think it's rather absurd to publish a review in 2024 whose latest literature search was more than ten years ago.

Very true. The 2024 version is said only to differ in the editorial note from the 2019, so you are right the 2024 article is based on a 2014 literature search.
Profoundly mis leading to a casual observer.

New versions of the review were published when the authors responded to some of the feedback and comments.
On PubMed I found the following versions of the review by Larun et al. (the first two versions of this review were by a different author team, namely Edmonds et al. in 2001 and 2004).

It seems that between 2019 and 2024 there was no new publication of the same review.
So for the editorial note that explained that the 2019 review was being updated, they did not published a new version. But to announce that this updated is cancelled, they did?

Does anyone have acces to the 2024 version? Has anyone checked if it is the same as the 2019 one but with the editorial note added to it?
I suppose it could just be a mistake by their web publishing team. In which case it can be corrected. While they’re at it they could just archive it 
Does anyone have the full new version of the review that they could share?
If I understand correctly, its because the amended review and the editorial note were published on the same day. See this page from October 2, 2019 - references both the publication of the amended review on that day and their intent to update.

That's possible but in the 2019 version I had stored, I can't find the editorial note. And in the version history it is dated at February 6 2020:
It's a bit confusing because the version history does not mentioned the new 2019 review and changes made to it.
EDIT: perhaps someone could download the text/PDF of the 2019 version here to see if it already contained the editorial note?

So some people (edit: or AI) seem to be keen to sell the review as 'new' on Xitter

That's an excellent comment.
I would go further and suggest that many of the criticisms apply more widely to literature on all sorts of behavioural interventions for all sorts of medical conditions. A careful consideration by Cochrane of the risk of bias in unblinded trials of interventions with only subjective outcomes, especially interventions aiming to change the way the patient interprets symptoms, had the potential, now squandered, to move the treatment of many conditions forward.
