-  * Fixes from upstream:
-    * liblzma: report a LZMA_DATA_ERROR when the first byte of range
-      encoded data is not zero.  This is a sanity check to catch
-      malformed files that no known encoders produce.
-    * The minimal xz version needed to decompress blocks with
-      zero-length uncompressed data is 5.0.2, not 5.0.3.
-    * xz.1: Document the new "minimum xz version to decompress"
-      field of "xz --robot -v -v --list" output.
-  * Lower priority of xz-utils to standard.  Closes: #685203.
+  * Apply fixes from 5.1.2alpha.  Closes: #685220.
