+## Implicit dependency fallback
+
+`dependency('foo')` now automatically fallback if the dependency is not found on
+the system but a subproject wrap file or directory exists with the same name.
+
+That means that simply adding `subprojects/foo.wrap` is enough to add fallback
+to any `dependency('foo')` call. It is however requires that the subproject call
+`meson.override_dependency('foo', foo_dep)` to specify which dependency object
+should be used for `foo`.
+
+## Wrap file `provide` section
+
+Wrap files can define the dependencies it provides in the `[provide]` section.
+When a wrap file provides the dependency `foo` any call do `dependency('foo')`
+will automatically fallback to that subproject even if no `fallback` keyword
+argument is given. See [Wrap documentation](Wrap-dependency-system-manual.md#provide_section).
+
+## `find_program()` fallback
+
+When a program cannot be found on the system but a wrap file has its name in the
+`[provide]` section, that subproject will be used as fallback.
