mongo-c-driver 1.3.1

It is my pleasure to announce MongoDB C Driver 1.3.1. This is a bugfix release:

• mongoc_client_get_gridfs now copies the client's read preferences, read
  concern, and write concern to the newly created mongoc_gridfs_t. Before
  this fix, GridFS operations were always executed with the default config:
  data was read from the primary, with the read concern level "local", and
  written with write concern "acknowledged". Now, if you have configured any
  of these options on the mongoc_client_t, they are respected by the
  mongoc_gridfs_t.
• CMakeLists.txt now includes and installs the pkg-config files.

Thanks to everyone who contributed to this release.
