v16.17.1

## Bug Fixes
* Displays the _Error Message_ in **Payroll Entry** as readable, formatted content with a link to the **Error Log**, instead of showing HTML code. (https://github.com/frappe/hrms/pull/5165)
* Adds **Expense Claim**, **Payroll Entry**, **Salary Slip**, **Leave Encashment**, and **Gratuity** to the audit trail list, allowing other apps to enable change tracking for these records. (https://github.com/frappe/hrms/pull/5175)
* Formats employee date and datetime values in **Salary Slip** PDF passwords according to the date format configured in **System Settings**, instead of always using the ISO format. (https://github.com/frappe/hrms/pull/5176)
* Skips exchange gain/loss calculations for advances linked to an **Expense Claim** when _Exchange Rate_ is missing or zero, instead of recording the allocated amount as a loss. (https://github.com/frappe/hrms/pull/5177)
