ap/ddrescue-1.26-x86_64-1.txz: Upgraded. d/parallel-20220122-noarch-1.txz: Upgraded. l/libimobiledevice-20211124_2c6121d-x86_64-2.txz: Rebuilt. Don't include compatibility pkgconfig symlink. It's unlikely that anything requires it. l/libimobiledevice-glue-20211125_3cb687b-x86_64-2.txz: Rebuilt. Removed broken pkgconfig symlink. Thanks to marav. isolinux/initrd.img: Rebuilt. usb-and-pxe-installers/usbboot.img: Rebuilt.
