Commit Message

Adolf Belka 8 Apr 2026, 8:23 p.m. UTC 
- The update to 1.0.21 resulted in libsodium not building on aarch64. A fix has b
   been developed and will ultimately be available with the next release. This uses that
   patch fix to be applied to 1.0.21
- Build tested on aarch64 and was successfull.
