MongoDB 3.0.0-rc11 is out and is ready for testing. This is the culmination of the 2.7.x development series.
3.0.0-rc11 fixes some backwards-breaking changes that were introduced in previous 3.0.0 release candidates.
Fixed in this release candidate:
SERVER-17372 FindAndModify no longer returns "value" if upsert results in an insert and "new" is false
SERVER-17356 Rename 'storageEngine' to 'storage' in collection and index options
SERVER-17280 Geo near must pass invalidation messages to index scan used by DensityEstimator
As always, please let us know of any issues.
