New in version 4.1.0.

To install built packages, PKGBUILDer uses transactions. A transaction stores:

  • package names (as requested by user), used for the validation step
  • package file names, moved to pacman cache and installed through pacman -U
  • signature file names, moved to pacman cache
  • options for running the transaction
  • a reference to the transaction file name (if any; .tx files are autosaved when status changes occur)

Package installation transactions.
