This is the first release candidate of the new MongoDB C++11 driver. This is a pre-release version of the driver and is not suitable for production use.

Please see our blog post for a full description of the new driver's design goals. The new driver is incompatible with all previous MongoDB C++ drivers. Due to the long history and complex version numbering of prior C++ drivers released by MongoDB, the C++11 driver is issuing its first stable release as 3.0.0. This is the lowest major version number that was found to be unambiguous with all previously released MongoDB C++ driver versions.

As specified in the Quickstart Guide, building the driver requires a conforming C++11 compiler (GCC 4.9, clang-3.4, VS 2015 Update 1, etc.) and depends on the 1.3 release of the MongoDB C Driver.

While we plan to commit to a stable ABI in the future, versions prior to 3.1.0 will not offer a stable ABI. The library currently has a soname ABI version of _noabi which indicates no API or ABI stability guarantee across any two releases. We are holding off on setting an ABI version so that we can incorporate post-GA feedback before locking down the ABI.

API documentation can be found here. Please file JIRA tickets if you encounter any problems using the driver. Pull requests against the master branch are welcomed and encouraged.

Please note the following known issues in this release:
