+-----------------------------------------
+
+* The :manual:`cmake(1)` ``-E tar`` tool now support Zstandard compression
+  algorithm with ``--zstd`` option. Zstandard was designed to give
+  a compression ratio comparable to that of the DEFLATE (zip) algorithm,
+  but faster, especially for decompression.
