I’m pleased to announce version 1.5.4 of libbson and libmongoc, the libraries constituting the MongoDB C Driver.
There is no change to libbson since 1.5.3; we released it to keep pace with libmongoc’s version.
The libmongoc release fixes an error in cursor iteration when a readConcern is set. Thanks to Jeremy Mikola and Hannes Magnusson.
