      What was accomplished since the last update?

      • GODRIVER-3956 is code complete and currently under review (PR #2558). It fixes a Windows-specific test flakiness issue tied to the epic's error-classification logic.
      • GODRIVER-4062 (Provide Updated Retryable Overload Error Code Examples for 9.0) is in progress.
      • Two new tickets were added to the epic's scope: GODRIVER-4108 and GODRIVER-4109. 
        • These were surfaced by Preston while reviewing GODRIVER-3908. Both are flaws where the driver would retry a server that is guaranteed to fail (OCSP and remote TLS cases).
        • The team agreed to fix these within the epic's scope to close known gaps rather than deferring to a later patch.

      What's the focus over the next two weeks?

      Any risks/blockers/impediments?

      • None currently blocking. The two newly added tickets slightly extend scope but are considered low-effort (~2.5 days each) and worth resolving before GA.
