-   For a new minor release (e.g., ``0.6.3 -> 0.7.0``): Create a pull request to
-   increment the dev version in of the master branch. See this
-   `sample PR for bumping a minor release version`_. **NOTE:** Not all of
-   the version numbers should be replaced. For example, ``0.7.0`` appears in
-   this file but should not be updated.
-   You will want to replace all instances of nightly wheel links (wheels with
-   dev in their name), instances of ``ray::stats::VersionKey``,
-   and instances of ``__version__``.
-
-   TIP: search the code base for instances of ``https://s3-us-west-2.amazonaws.com/ray-wheels/latest/ray-1.1.0.dev0`` (but replace ray-1.1.0 with the current version) to find links to the nightly wheel to update.
-
-   You should also cherry pick parts of this pull request referencing the
-   latest wheels onto the release branch prior
-   to making the release. This will ensure that the ``install-nightly`` of
-   the new release correctly points at the latest version on master.
-
-   Note: Doing this will cause the ``install-nightly`` CLI command of the
-   current Ray release to fail, so you should only merge this PR when
-   the release is about to occur. (For instance, the 1.0.0 ``install-nightly``
-   command points to 1.1.0.dev0, so when you bump master to 1.2.0.dev0, it no
-   longer finds the latest commit.)
