I’ve seen that ArchlinuxARM updated their glibc package to v2.33-5 on May 17th : glibc (arm) | Package Log | Arch Linux ARM
(my previous post was too early : Glibc difference between ARM and X86 )
If I can see it well Manjaro ARM version is stucked to v2.32-2. I can’t find the PKGBUILD on gitlab : core · GitLab
It should be noted that the version has been upgraded to v2.34 on the gnu site and Archlinux x86 will update soon…
