xdelta 3.0.11 enables LZMA secondary compression by default, which breaks compatibility with xdelta < 3.0.4 (e.g. Ubuntu 12.04), xdelta < 3.0.8 on Windows, and any newer xdelta not linked with liblzma. This is not mentioned in the release notes.
As a workaround, encoding with -S none will disable secondary compression, but that possibility is not documented in the -h output or man page.
