v16.4.8

## Bug Fixes
* Shows or hides base currency fields in **Employee Advance** and **Expense Claim** forms according to the record’s currency. Prevents selecting an _Advance Account_ in a mismatched currency and updates existing records with correct currency data. (https://github.com/frappe/hrms/pull/4309)
* The _Advances_ section in **Expense Claim** now lists only advances issued to the same employee and stops submission if a different employee’s advance is selected. (https://github.com/frappe/hrms/pull/4317)
* Adds multi-currency handling to **Expense Claim** and **Employee Advance** forms, with dynamic labels for transaction and company amounts and automatic exchange-rate updates. Adds a currency column to the **Expense Claim** list and refreshes dropdown options when filters change. (https://github.com/frappe/hrms/pull/4318)
* Displays formatted content in rich-text fields like _Description_ in **Expense Item** on the PWA by replacing the plain input with a text editor, so raw HTML no longer appears. (https://github.com/frappe/hrms/pull/4321)
* Fixes the server error that occurred when filtering employees by _Grade_ in the **Employee Attendance Tool**, so the list now shows only employees matching the selected grade. (https://github.com/frappe/hrms/pull/4327)
* Adds explanatory text to the _Include Holidays_ checkbox in **Attendance Request** and replaces the generic error with a table that lists the date, reason, and suggested action when attendance cannot be created. (https://github.com/frappe/hrms/pull/4329)
* Adds an option to create a "Payment Entry" directly from an **Expense Claim**, allowing users to record payments without leaving the form. (https://github.com/frappe/hrms/pull/4336)
* Expired **Shift Assignment** records are now set to _Inactive_ during the daily update, preventing past shifts from being included in attendance calculations. (https://github.com/frappe/hrms/pull/4334)
* Fixes calculation of future taxable earnings in **Salary Slip** for fortnightly payrolls, preventing inflated projected salary and tax amounts. The system now projects the correct number of remaining pay periods. (https://github.com/frappe/hrms/pull/4338)
* Removes a duplicate version update step in the automatic update workflow, eliminating redundant repository operations during updates. (https://github.com/frappe/hrms/pull/4347)
* Prevent the "Condition and Formula" section in **Salary Structure** from collapsing when you enable _Amount Based on Formula_ or edit the _Formula_ field. The _Amount Based on Formula_ and _Formula_ columns no longer appear in the salary component list view. (https://github.com/frappe/hrms/pull/4350)
