NDB 0.4 released!
Guido van Rossum
Plus release 0.4). This marks a pretty major milestone, with
MultiQuery now supporting pretty much all features (even cursors,
though with some limitations), and exceptions propagating from queries
to callers (no more deadlocks!).
For our readers on google-appengine-python, NDB is an experimental (!)
datastore client API for Python, which I am developing as an open
source project. Contributions and feedback are requested!

Detailed changes:
- Add API to set memcache timeout policy (issue 16)
- Special-case Rollback exceptions in transactions (issue 27)
- Support taskqueue transactions (issue 21)
- LocalStructuredProperty allows models with repeated properties
- Much improved MultiQuery functionality (issue 26)
- Handle Unicode property names, UTF-8 kind names
- Exceptions from queries are propagated correctly (issue 22)
- Fix queries for blob values (issue 30)
- fetch() and count() can now be called without a limit argument
Note that you now need App Engine SDK version 1.5.1 (1.5.0 might
mostly work except cursor support for MultiQuery).

You think it'll ship in the next SDK? ;)

Thanks!
I have a personal goal to ship it as an experimental package before
the end of Q3. There's a lot to do yet -- have you seen the number of
TODOs? :-) Also the docs need work, esp. the async docs. But we'll get
there!
