 ## Fixes
 
+* Windows Secure Channel is fixed to support newer signatures to verify client certificates.
+* Replace use of `rand()` with thread-safe alternatives.
 * The uninstall script for Windows is fixed so it no longer "succeeds" with a non-zero `%ERRORLABEL%` value.
 * The uninstall script for non-Windows environments now calls `find "$dir" -maxdepth 1` instead of `ls --almost-all "$dir"` when detecting non-empty directories to fix macOS compatibility.
 
+## Improvements
+
+* Remove unhelpful long-lived buffers to reduce memory usage.
+* Improve error messages produced by Windows APIs.
+
 ## Notes
 
 * The minimum supported MongoDB Server version is raised from 4.0 to 4.2. This is in accordance with [MongoDB Software Lifecycle Schedules](https://www.mongodb.com/legal/support-policy/lifecycles).
