   * liblzma:
     - Remove compatibility tricks that permit sharing a process with
       liblzma.so.2.  This means liblzma.a no longer depends on libdl
       at run time.
       Closes: #919950.  Thanks to Josh Triplett.

+  * xz-utils/README.Debian: Remove notes about differences from
+    upstream.

-Differences from standard XZ Utils
-----------------------------------
-
-XZ Utils 5.1.y has some experimental features which are disabled in
-Debian to allow interfaces to evolve.
-
-abi-threaded-encoder
-  Disable threaded compression in liblzma and xz.
-
-abi-version-script
-  liblzma: Do not pretend to satisfy dependencies on XZ_5.1.1alpha.
-
-man-date, man-xz-lvv-minver (from upstream)
-  Document the "Minimum version required to decompress" field of
-  "xz --robot -v -v --list" output.
-
-xz-lvv-empty-block-minver (from upstream)
-  Fix the version number printed by "xz -lvv" for files with Blocks
-  of zero uncompressed_size: the decoder bug preventing reading such
-  files was fixed in xz 5.0.2, not 5.0.3.
-
-decoder-check-first-0x00 (from upstream)
-  Check that the first byte of range encoded data is zero to catch
-  broken files sooner.
-
-Changes in 5.1.2alpha not applied:
-
-  Docs: Language fix to 01_compress_easy.c
-  xz: Add incomplete support for --block-list
-  INSTALL: Document --enable-symbol-versions
-  configure: Add a comment about *-linux tuples for clarity
-  TODO: Warn that threads and fork() do not mix well
-  Bump the version number and update NEWS for 5.1.2alpha
