 # Version (development version)

+## New Features
+
+ * Now the 'callr' backend finalizes the 'callr' process as soon as
+   the future results have been collected. This results in removing
+   temporary files created by **callr** sooner. Previously, the
+   finalizer was only run when the future object was removed and
+   garbage collected.
