+- Update to new upstream release 1.7
+* The fast encoder, which produces a compression speed and ratio
+  comparable to those of gzip, has been ported from lzip.
+* The option "-0" has been ported from lzip to minilzip.
+* If all the data to be compressed are written in advance, lzlib
+  will automatically adjust the header of the compressed data to
+  use the smallest possible dictionary size. This feature reduces
+  the amount of memory needed for decompression and allows minilzip
+  to produce identical compressed output as lzip.
