 - Corrects the misspelled `customer_vendor_webiste` field to `customer_vendor_website` in `quickbooks__ap_ar_enhanced`.
 
 ## Bug Fixes
-- Updates the [quickbooks__profit_and_loss](https://github.com/fivetran/dbt_quickbooks/blob/main/models/quickbooks__profit_and_loss.sql) and [quickbooks__balance_sheet](https://github.com/fivetran/dbt_quickbooks/blob/main/models/quickbooks__balance_sheet.sql) models to include both `period_first_day` and `period_last_day`. This allows users to have greater flexibility in choosing which date to aggregate records upon.
 - Updates the logic for the `amount` field in [int_quickbooks__invoice_double_entry](https://github.com/fivetran/dbt_quickbooks/blob/main/models/double_entry_transactions/int_quickbooks__invoice_double_entry.sql) to use `invoice.total_amount` only on the condition when a bundle is associated with the invoice and `invoice.total_amount` is 0, otherwise `invoice_lines.amount` is used. 
    - This avoids double counting when aggregating invoice_line items and accounts for the edge cases where a bundle_id is involved.
 
+## Feature Updates
+- Updates the [quickbooks__profit_and_loss](https://github.com/fivetran/dbt_quickbooks/blob/main/models/quickbooks__profit_and_loss.sql) and [quickbooks__balance_sheet](https://github.com/fivetran/dbt_quickbooks/blob/main/models/quickbooks__balance_sheet.sql) models to include both `period_first_day` and `period_last_day` in addition to `calendar_date`. This allows users to have greater flexibility in choosing which date to aggregate records upon.
+  - Please note `calendar_date` is slotted to be deprecated, and the fields `period_first_day` and `period_last_day` are both offered as replacements, depending on how your company performs their financial reporting.
