This is the second patch release of the new MongoDB C++11 driver. Please see the release notes for the 3.0.1 driver below for additional details on this new driver.
Please note that this version of the driver requires the MongoDB C driver 1.3.4 in order to build and exhibit expected behavior.
The MongoDB C++11 driver 3.0.x series does not promise API or ABI stability across patch releases. There are some minor API breaking changes in the 3.0.2 release. We apologize for any inconvenience. We are aiming to achieve API stability for the upcoming 3.1.x series. Some known changes include:
- bsoncxx::oid objects are now default initialized to a valid state
- JSON-ification of element and types has been removed
- JSON formatting has changed to use libbson's JSON algorithm
