This patch release addresses compilation issues when compiling without a polyfill on C++17 supporting compilers.

Please note that this version of mongocxx requires the MongoDB C driver 1.13.0.

See the MongoDB C++ Driver Manual and the Driver Installation Instructions for more details on downloading, installing, and using this driver.

NOTE: The mongocxx 3.4.x series does not promise API or ABI stability across patch releases.

Here is the full list of user-visible issues that have been resolved in 3.4.1 since the prior 3.4.0 release:

Bug

• [CXX-1688] - MongoDB CXX driver does not compile with standard polyfill.
• [CXX-1689] - database::_create_collection is not using C++17-compatible string conversion.
