I'm pleased to announce version 1.17.0-beta2 of libbson and libmongoc,
the libraries constituting the MongoDB C Driver.

libbson

It is my pleasure to announce libbson 1.17.0 beta2.

Features:

• Fix pedantic compiler warnings.
• Improve assertion error messages.

Bug fixes:

• Fix possible int32 overflow when comparing and constructing large bson_t's.

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.17.0 beta2 release.

Features:

• Support Online Certificate Status Protocol (OCSP) response caching.
• Support configuring hedged reads in read preferences.
• Reduce the number of round trips necessary for SCRAM and X509 authentication.
• Monitor servers in parallel when using a mongoc_client_pool_t instead of doing serial scans.
• Support OCSP on older versions of OpenSSL (1.0.1+).

Bug fixes:

• Fix behavior of a SecondaryPreferred read preference for exhaust cursor operations against a sharded cluster. Prior to the fix, a nonzero maxStalenessSeconds would not trigger sending the read preference.
• Fix SRV polling. Prior to the fix, SRV polling did not properly apply newly discovered results.
• Fix checks for existing GridFS indexes to handle indexes created by the MongoDB shell.
