Announcing 2.1.0 of libbson and libmongoc, the libraries constituting the MongoDB C Driver.

libbson

Fixes

• The uninstall script for Windows is fixed so it no longer "succeeds" with a non-zero %ERRORLABEL% value.
• The uninstall script for non-Windows environments now calls find "$dir" -maxdepth 1 instead of ls --almost-all "$dir" when detecting non-empty directories to fix macOS compatibility.

Changed

• The CMake project now sets a CMake policy max version of 4.0 (previously unset).

Removed

• Support for Debian 9 and Debian 10.
