+- Update to new upstream release 1.21~rc1
+  * The options '--dump', '--remove' and '--strip' have been
+    added, mainly as support for the tarlz archive format.
+  * Detection of forbidden combinations of characters in trailing
+    data has been improved.
+  * '--split' can now detect trailing data and gaps between
+    members, and save each gap in its own file. Trailing data (if
+    any) are saved alone in the last file. (Gaps may contain
+    garbage or may be members with corrupt headers or trailers).
+  * '--ignore-errors' now makes '--list' show gaps between
+    members, ignoring format errors.
+  * '--ignore-errors' now makes '--range-decompress' ignore a
+    truncated last member.
+  * '--ignore-errors' now makes '--dump', '--remove' and
+    '--strip' ignore format errors.
