 Below we highlight some key changes to the defaults in OPA 1.0:
 
-- The `if` & `contains` keywords are now mandatory when declaring rule heads, not just when using the `rego.v1` import.
+- Using `if` for all rule definitions and `contains` for multi-value rules is now mandatory, not just when using the `rego.v1` import.
 - Other new keywords (`every`, `in`) are available without any imports.
-- Previously rules reserved for `opa check --strict` are now the default. Duplicate imports and imports which shadow each other are no longer allowed.
+- Previously requirements that were only run in "strict mode" (like `opa check --strict`) are now the default. Duplicate imports and imports which shadow each other are no longer allowed.
 - OPA 1.0 comes with a range of backwards compatibility features to aid your migrations, please see the [v0 compatibility guide](https://www.openpolicyagent.org/docs/edge/v0-compatibility/)
 if you must continue to support v0 Rego.
