+"graphile-build": patch
+---
+
+Fix bug where creating the build object also initialized it; this is incorrect
+since if you just want the build object you don't necessarily want to register
+all of the GraphQL types (and potentially discover naming conflicts) at that
+moment. Introduced new
+`schemaBuilder.initBuild(schemaBuilder.createBuild(input))` API to explicitly
+handle initing if you need an initialized build object.
