+5.0.4 (2012-06-22)
+
+    * liblzma:
+
+        - Fix lzma_index_init(). It could crash if memory allocation
+          failed.
+
+        - Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ
+          filter is used and the application only provides exactly as
+          much output space as is the uncompressed size of the file.
+
+        - Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't
+          check if the last call to lzma_code() really returned
+          LZMA_STREAM_END, which made the program think that truncated
+          files are valid.
+
+        - New example programs in doc/examples (old programs are now in
+          doc/examples_old). These have more comments and more detailed
+          error handling.
+
+    * Fix "xz -lvv foo.xz". It could crash on some corrupted files.
+
+    * Fix output of "xz --robot -lv" and "xz --robot -lvv" which
+      incorrectly printed the filename also in the "foo (x/x)" format.
+
+    * Fix exit status of "xzdiff foo.xz bar.xz".
+
+    * Fix exit status of "xzgrep foo binary_file".
+
+    * Fix portability to EBCDIC systems.
+
+    * Fix a configure issue on AIX with the XL C compiler. See INSTALL
+      for details.
+
+    * Update French, German, Italian, and Polish translations.
