+- update to version 2.6.8:
+  * Add check to make sure that f_locals is not actually f_globals
+    when we do the f_locals clear to avoid the #310 memory leak issue.
+  * Compare NumPy versions using distutils.version.LooseVersion to
+    avoid issue #312 when working with NumPy development versions.
+  * As part of multibuild, wheels for Python 3.7 for Linux and MacOSX
+    are now available on PyPI.
+
+- changes from version 2.6.7:
+  * Thanks to Lehman Garrison for finding and fixing a bug that
+    exhibited memory leak-like behavior. The use in numexpr.evaluate
+    of sys._getframe combined with .f_locals from that frame object
+    results an extra refcount on objects in the frame that calls
+    numexpr.evaluate, and not evaluate's frame. So if the calling
+    frame remains in scope for a long time (such as a procedural
+    script where numexpr is called from the base frame) garbage
+    collection would never occur.
+  * Imports for the numexpr.test submodule were made lazy in the
+    numexpr module.
