+# Release Notes for Lunchy v1.4.0
+
+This release introduces a new pay reminder feature, offering the following configuration options to manage payment reminders after a poll has closed:
+
+```yaml
+paying_feature:
+  enabled: true  # Enable or disable the payment reminder feature.
+  emoji: "💸"    # The emoji used to confirm payment on the closed poll summary. Paid users react with this emoji.
+  auto_send_emoji: true # Automatically react to poll summary message with the payment confirmation emoji.
+  reminder_delay: "1h" # The time after which unpaid users will be reminded to pay. Examples: "30m", "1h", "24h", "7d".
+```
+
+When a poll closes, the bot waits for users to react to the poll summary. If the user does not react to the summary within the `reminder_delay`, they will receive a payment reminder mention.
