+  When an import cannot be resolved using the active modules,
+  the <code>go</code> command will now try to use the modules mentioned in the
+  main module's <code>replace</code> directives before consulting the module
+  cache and the usual network sources.
+  If a matching replacement is found but the <code>replace</code> directive does
+  not specify a version, the <code>go</code> command uses a pseudo-version
+  derived from the zero <code>time.Time</code> (such
+  as <code>v0.0.0-00010101000000-000000000000</code>).
