We are happy to announce that MongoDB v1.8.0 is now available. 1.8 is the stable follow-up release to 1.6, which came out in August of 2010. Version 1.8 introduces many new features, along with bug fixes and other improvements. Some of the highlights:
- Journaling
- Sharding performance improvements
- Replica set enhancements, including support for authentication
- Spherical geo search
- Covered and sparse indexes
- B-tree index self-compaction
- New map/reduce options for incremental updates
- Tab completion in the shell

A journaling storage engine has been one of the most requested and discussed features within the MongoDB community, and we’re happy to announce that journaling is now available. With journaling enabled, crash recovery is fast and safe.
There were no major changes to sharding, but this release includes many internal improvements, making for a vastly improved experience. As an example, splitting and balancing are considerably faster, with less impact on the overall system.

Thanks to the MongoDB user community for providing feedback and for testing through the 1.7.x development series.
