You could use the namespace attribute of memcache.add/set/etc.
In a global settings/config file, set the namespace to be your
released version number and then adjust all of your memcache calls to
use this namespace.
On a new release, the existing items will remain, but they will fall
out over time (and your application won't see them because it's on a
different namespace).
This doesn't play nice with the Multi-tenancy API, so if you need to
use that, you'd have to instead adjust your cache keys to be prefixed
with your released version id.
E.g., in Python:
settings.py
RELEASED_VERSION = 'V1' # your build/deployment script would update
this
--
some_other_file.py
import settings
from google.appengine.api import memcache
def foo():
memcache.get('your-cache-key', namespace=settings.RELEASED_VERSIOIN)
# (or)
def bar():
cache_key = 'your-cache-key'
memcache.get('%s:%s' % (settings.RELEASED_VERSION, cache_key))
