+  * Team upload.
+  * Readd m4-hdf5.patch in d/patches/series, which had been mistakenly
+    removed in version 5.5.1-4. Remove hdf5-libsz.diff which has been
+    introduced in replacement.
+  * Also readd remove-exit.diff.

+scilab (5.5.1-6) unstable; urgency=medium
+
+  * Team upload.
+  * Readd m4-java-ppc64el.patch in d/patches/series. It had been
+    mistakenly removed in the previous upload. This fixes the FTBFS on
+    ppc64el. (Closes: #776525)
+  * Fix a mistake in the above patch concerning bin/scilab. The machine
+    name (output of 'uname -m') is ppc64le and not ppc64el. This error
+    was making scilab unable to start on ppc64el.

 scilab (5.5.1-5) unstable; urgency=medium
