+  #845. Much thanks to Adhemerval Zanella and github user mtone.
+
+* Romain Geissler contributed build fix for -std=c++17. This is pull
+  request #897.
+
+* As part of fixing issue #904, tcmalloc atfork handler is now
+  installed early. This should fix slight chance of hitting deadlocks
+  at fork in some cases.
