MongoDB C driver 1.17.3 released

I’m pleased to announce version 1.17.3 of libbson and libmongoc,
the libraries constituting the MongoDB C Driver.


Bug fixes:

  • Do not send session ID on GSSAPI auth commands.
  • Fix build against zlib when zlib is installed in non-standard location.
  • Fix build when source directory path contains a space.
  • Fix a platform-specific bug causing mongoc_client_pool_pop to block indefinitely if all clients are checked out.
  • Fix a possible buffer overflow with hostnames resolving to IPv6 addresses on OpenSSL.


No changes since 1.17.2; release to keep pace with libmongoc’s version.


Thanks to everyone who contributed to this release.
