MongoDB 3.0.6 在 8 月 20 日发布了 RC1 和 RC2 版本，估计很快就会正式发布，现在 dl 上已经提供 Windows 版本的下载：https://www.mongodb.org/dl/win32/x86_64-2008plus-ssl。暂未找到相关说明。

同时还发布了 MongoDB 3.1.7 版本，这是开发版本，不建议在生产环境使用。

主要改进：

• clusterManager role does not have permission for adding tag ranges

• $sort stage in aggregation doesn’t call scoped connections done ()

• runcating a capped collection may not unindex deleted documents in WiredTiger

• Seg Fault on cloneCollection (specifically gridfs)

• Excessive memory allocated by WiredTiger journal

• Fatal error calling createIndex with 2dsphere

• MMap memory mapped file address allocation code cannot handle addresses non-aligned to memory mapped granularity size

• Mongo shell should report that subprograms exited with non-zero exit code if they die
