,----< from http://tukaani.org/lzma/ >
| * New header format: adds magic bytes, filter support and CRC32

And the download page says that the current version of the legacy code
base (4.32.4) has support for detecting the new header.  From that src
there is this:

,----[ lzma-4.32.4/extra/magic/lzma.magic ]
| 0x00    ustring         \xFFLZMA\x00    lzma compressed data,
| >0x06   ubyte&0x10      0x00            single-block stream
| >0x06   ubyte&0x10      0x10            multi-block stream

So it looks like they have it covered.

(For those looking at their git repos, I only find the magic file in
the legacy repo <git://ctrl.tukaani.org/lzma-utils-legacy.git> and not
in the new codebase <git://ctrl.tukaani.org/lzma-utils.git>.)
