Java

Google App Engine SDK 1.5.4 has been released
for Java. This release introduces the ability to limit the blob
upload size, and the number of write operations required to store
an entity in the SDK dataviewer are now displayed. The SDK also
includes an experimental Java version of the Prospective Search
API, which allows users to detect and take action on datastore
entities that match certain criteria when they are written. More
information is available at the Release Notes.

Google App Engine SDK 1.5.4 for Python is also available.

 

MongoDB Database Reaches 2.0

The MongoDB team have released version 2.0 of the MongoDB document-oriented
database. This release introduces a compact command for compacting
a single collection and its indexes, and the default stack size has
been reduced. MongoDB users can now use authentication with sharded
clusters. Replica data set members can be tagged to indicate their
locations, and these tags can then be used to design custom written
rules across specified servers, racks, or other architecture
choices. New geospatial features have also been introduced,
including support for indexing on documents which have multiple
location objects, and support for polygonal $within queries for
simple polygon shapes. More information on the new features, is
available at the Release Notes.
