-<!-- Perf results go here -->
+A week with lots of mixed results, including a few benchmarks that appear to be
+newly bimodal, which made some of the results look closer to noise than signal.
+Overall, however, the week ended as a slight improvement.

 are the RFCs that were approved for implementation this week:
 
-<!-- Approved RFCs go here, use this format: * [Topic](URL) -->
-<!-- or if none were approved this week, use: * *No RFCs were approved this week.* -->
-<!-- * []() -->
