App Engine legacy bundled services private preview

[wesley c]

To Java 8, Python 2, and Go 1.11 (or earlier) App Engine users:

In order to help with modernizing your apps to newer language releases, the App Engine team is broadening the participation in our private preview of the legacy bundled services. Previously, users have had to migrate from bundled services like App Engine Datastore, Memcache, Task Queues, etc., to their standalone, unbundled equivalent, i.e., Cloud Datastore, Cloud Memorystore, Cloud Tasks, etc., before upgrading to the second generation App Engine Java 11, Python 3, PHP 7, and Go 1.12 (and newer) runtimes.

Now by accessing these private preview features, you can do the vice versa: upgrade to the modern language runtimes, then migrate to the new standalone services on your own time. The legacy services we are making available are meant to aid you as a migration tool. Be aware that new features and product innovations will only take place in the newer standalone services, so we do recommend upgrading when possible. Here is what's currently available in the private preview (with more on the way soon):

Feature	Java 11	Python 3	Go 1.12+
Datastore	✔	✔	✔
Memcache	✔	✔	✔
Blobstore	✔		✔
Task Queues	✔		✔
URLfetch	✔	✔	✔
Mail	✔
Users	✔		✔
Images	✔
