Well I don't know your script, and I am not sure how exactly you do that 
in svn....

Also I do not know, if this is for a once up setup (so you only wont to 
download the one revision and nothing else), or if you don't mind.
(I have not measured the overhead..>)

Most replies will be to clone all, and then look at tags. (or branches)
But you can do ( -t => tags) https://git-scm.com/docs/git-ls-remote.html

     git ls-remote -t https://gitlab.com/freepascal.org/lazarus/lazarus.git

However, there is no "svn serial rev number", nor a date. So you need to 
parse the "release version" number, and compare them.

If you have a complete clone, you can afaik sort them by "commit date" 
(see "git for-each-ref")

If you do not want to clone

git init .
git fetch --depth=1 
git switch -c my-branch FETCH_HEAD

"my-branch" is your choice

I haven't tested how well updates work, if you go to other branches.
Since you have no history fetched (depth =1), I expect a full download 
of any other version (unless it is a direct child / same branch, NOT 

Git is written for getting the full history once. I *guess* (but might 
be totally wrong) that not doing so, will make you pay later.
You could do a depth of 3000 or 10000.
That is 2.2.0 (with the ending 0) is likely less that 3000 commits 
divirged from main. Then that gives you common history, and 2.4 can base 
on that.

2.0.18 is probably more revisions from main.

If you only want to stay in the same fixes branch (and are ok with a new 
download for major releases) go with a depth of 500. It is unlikely that 
a release tag will be further away from its fixes branch (usual are 0 to 
5 commits)
