MongoEngine 0.4 Released

The long-awaited version 0.4 of MongoEngine has now been released. This is a major update, bringing a solid set of new features, optimisations and bug fixes. I’ll outline some of the main changes, and link to the documentation where relevant.

• Completely re-written Q-object implementation that no longer uses Javascript. A lengthier post on these will be coming soon, but basic point is that they should be a lot faster, more maintainable and less buggy as they now use native MongoDB queries.
• Support for GridFS through the FileField (docs)
• Geospatial querying support. This is implemented though the GeoPointField and the near, within_box and within_distance query operators (docs)
• New SortedListField and EmailField (docs)
• New QuerySet methods: distinct(), create(), snapshot(), timeout() and all()

For the slightly longer list of changes, check out the changelog.

To get going with 0.4, upgrade using pip install -U mongoengine and have a read of the new documentation.

And a massive thanks to everyone who contributed code and submitted bug reports.
