+Performance Improvements
+------------------------
+
+- Block validation can now prefetch input prevouts from the chainstate database
+ in parallel while connecting blocks, speeding up validation when prevouts need
+ to be read from disk. A new `-prevoutfetchthreads=<n>` option controls the
+ number of prefetch worker threads. The default is 8 threads, up to a maximum
+ of 16; set it to 0 to disable parallel prefetching. (#35295)
