+## Consistency between `declare_dependency()` and `pkgconfig.generate()` variables
+
+The `variables` keyword argument in `declare_dependency()` used to only support
+dictionary and `pkgconfig.generate()` only list of strings. They now both support
+dictionary and list of strings in the format `'name=value'`. This makes easier
+to share a common set of variables for both:
+
+```meson
+vars = {'foo': 'bar'}
+dep = declare_dependency(..., variables: vars)
+pkg.generate(..., variables: vars)
+```
