+- specfile:
+  * build with flit

+      (thanks to rhettinger)
+  * Changes to existing functions
+    + The :func:`ichunked` function is now more efficient (thanks to
+      hjtran0 and seanmacavaney)
+    + The :func:`difference` function is now more efficient (thanks to
+      Masynchin)
+    + The :func:`grouper` recipe now has more features, mirroring the
+      one in the itertools docs (thanks to rhettinger)
+  * Other changes
