+Breaking changes:
+- `database` and `schema` are right now under `in` field
+- `row_access_policies` field now organizes output of show under `show_output` field and the output of describe under `describe_output` field.

 ### snowflake_row_access_policy resource changes
 New fields:
   - `show_output` field that holds the response from SHOW ROW ACCESS POLICIES.

 ## Schema
 
-### Required
+### Optional
 
-- `database` (String) The database from which to return the schemas from.
-- `schema` (String) The schema from which to return the row access policy from.
+- `in` (Block List, Max: 1) IN clause to filter the list of row access policies (see [below for nested schema](#nestedblock--in))
+- `like` (String) Filters the output with **case-insensitive** pattern, with support for SQL wildcard characters (`%` and `_`).
+- `limit` (Block List, Max: 1) Limits the number of rows returned. If the `limit.from` is set, then the limit wll start from the first element matched by the expression. The expression is only used to match with the first element, later on the elements are not matched by the prefix, but you can enforce a certain pattern with `starts_with` or `like`. (see [below for nested schema](#nestedblock--limit))
+- `with_describe` (Boolean) Runs DESC ROW ACCESS POLICY for each row access policy returned by SHOW ROW ACCESS POLICIES. The output of describe is saved to the description field. By default this value is set to true.
 
 ### Read-Only
 
 - `id` (String) The ID of this resource.
-- `row_access_policies` (List of Object) The row access policy in the schema (see [below for nested schema](#nestedatt--row_access_policies))
+- `row_access_policies` (List of Object) Holds the aggregated output of all views details queries. (see [below for nested schema](#nestedatt--row_access_policies))

+### Nested Schema for `in`
+
+Optional:
+
+- `account` (Boolean) Returns records for the entire account.
+- `application` (String) Returns records for the specified application.
+- `application_package` (String) Returns records for the specified application package.
+- `database` (String) Returns records for the current database in use or for a specified database.
+- `schema` (String) Returns records for the current schema in use or a specified schema. Use fully qualified name.
+
+
+<a id="nestedblock--limit"></a>
+### Nested Schema for `limit`
+
+Required:
+
+- `rows` (Number) The maximum number of rows to return.
+
+Optional:
+
+- `from` (String) Specifies a **case-sensitive** pattern that is used to match object name. After the first match, the limit on the number of rows will be applied.
+
 
 <a id="nestedatt--row_access_policies"></a>
 ### Nested Schema for `row_access_policies`
 
 Read-Only:
