can we pin this to the exact version please, then we don't have any changes to joomla it self (the changes in the lib are only codestyle and readme update, so no relevant code changes).

in 4.3 we already use the latest version so nothing needs to be changed in this branch.

[Fedik]

I tried exact version, but composer complain that it do not see symfony/polyfill-php81 in lock file, or dron fail.
So I have no idea, and just updated these two 😉

If there is a polyfill for 7.3, 8.0 and 8.1, is there also one for 7.4?

[Fedik]

Yes there is https://github.com/symfony/polyfill-php74
But I do not think that we use any of these 3 methods 😉

[Fedik]

Maybe I better move it to 4.3, or?

@roland-d and @fancyFranci this is missing for 4.2.9
