+11. **Bump version on Ray master branch:** Create a pull request to increment the
+    version of the master branch. The format of the new version is as follows:
+
+    New minor release (e.g., 0.7.0): Increment the minor version and append ``.dev0`` to
+    the version. For example, if the version of the new release is 0.7.0, the master
+    branch needs to be updated to 0.8.0.dev0. `Example PR for minor release`
+
+    New micro release (e.g., 0.7.1): Increment the ``dev`` number, such that the number
+    after ``dev`` equals the micro version. For example, if the version of the new
+    release is 0.7.1, the master branch needs to be updated to 0.8.0.dev1.
+
+12. **Update version numbers throughout codebase:** Suppose we just released 0.7.1. The
+    previous release version number (in this case 0.7.0) and the previous dev version number
+    (in this case 0.8.0.dev0) appear in many places throughout the code base including
+    the installation documentation, the example autoscaler config files, and the testing
+    scripts. Search for all of the occurrences of these version numbers and update them to
+    use the new release and dev version numbers.
