-# 1.0.0 (unreleased)
-
-* 1.0.0 will introduce breaking changes, including removing support for symbols. To update, change snake-case symbols to their correct column names (for example, `record["First Name"]` instead of `record[:first_name]`)
-* Implement associations as instance methods, e.g.
-    ```ruby
-    tea.brews #=> [<Brew>, <Brew>] returns associated models
-    tea["Brews"] #=> ["rec456", "rec789"] returns a raw Airtable field
-    ```

+* 1.0.0 introduces breaking changes, including removing support for symbols and
+  implementing associations as instance methods. To upgrade:
+  1. Change snake-case symbols to their correct column names:
+    `record["First Name"]` instead of `record[:first_name]`)
+  2. Change your association calls to use instance methods instead of `[]`:
+      ```ruby
+      class Tea < Airrecord::Table
+        has_many :brews, class: "Brew", column: "Brews"
+      end
+      tea[:brews] #=> Error, no longer supported
+      tea.brews #=> [<Brew>, <Brew>] returns associated Brew instances
+      tea["Brews"] #=> ["rec456", "rec789"] returns a raw Airtable field
+      ```
+  3. Dates that are formed `\d{4}-\d{2}-\d{2}` are no longer auto-parsed. Define a helper instead.
 * Automatically throttle client calls to Airtable's API limit of 5 requests per second.
 * Fix sorting by multiple fields
 * Report `User-Agent` as `Airrecord`.
-* Dates that are formed `\d{4}-\d{2}-\d{2}` are no longer auto-parsed. Define a helper instead.
