MongoDB C driver 1.17.0-rc0 released

I’m pleased to announce version 1.17.0-rc0 of libbson and libmongoc,
the libraries constituting the MongoDB C Driver.

It is my pleasure to announce the MongoDB C Driver 1.17.0 rc0 release.
This release adds support for MongoDB 4.4 servers.


  • Support streamable server monitoring to reduce recovery time when the server topology changes.
  • Support tlsDisableCertificateRevocationCheck when built with Secure Channel.

Bug fixes:

  • Fix criteria for resumable errors in change streams.
  • Fix rare crashes when server is invalidated during authentication.
  • Improve behavior when reaching out to OCSP responders for certificate revocation checking.
  • Reject client session for mongoc_collection_estimated_document_count.

Thanks to everyone who contributed to the development of this release.

  • Kevin Albertson
  • Andrew Witten
  • Roberto C. Sánchez
  • Clyde Bazile

No changes since 1.17.0 beta2; release to keep pace with libmongoc’s version.
