+The LDK 0.1 release represents an important milestone for the LDK project. While
+there are certainly many important features which are still being built, the LDK
+project has come a long way, and the LDK project is happy with the quality of
+the features included in this release. Thus, the project will begin doing patch
+releases to fix bugs in prior versions as new features continue to ship in new
+minor versions.
