[!IMPORTANT]

Internal Changes for an Upcoming Feature

This release includes low level changes to internal subsystems including operation execution, timeout handling, and resource cleanup logic - in preparation for supporting Client-Side Operations Timeout (CSOT) in an upcoming release.

If you experience unexpected issues such as:

  • Operations timing out unexpectedly or not timing out when expected
  • Unusual delays or hangs in database calls
  • Differences in command cancellation behavior

Please let us know via the MongoDB JIRA Driver project or your MongoDB support channel, providing driver logs and a reproduction if possible.
