Bug fixes
Lending
Incorrect installment status handling after custom principal repayments
We have corrected a behavior where installments marked as Paid under the Principal Expected is Paid setting would revert to Partially Paid after a custom principal repayment was posted.
Interest rate changes no longer affect settled advance payments
We've resolved an issue where interest rate adjustments incorrectly recalculated installments already settled via advance payments, ensuring accurate loan schedules and consistent repayment tracking.
Interest rate changes now preserve paid installment status
When an Interest Rate Change is made with an effective date before a Paid installment, the system now ensures the update only applies to Pending or Partially Paid installments.
Planned fees now included in total expected schedule amounts
When generating loan account documents, planned fees are now correctly included in the total expected schedule amount, ensuring accurate totals are displayed.
Resolved loan account editing and deletion with planned fees
Editing or deleting a loan account that had planned fees associated with it no longer fails unexpectedly due to improved planned fee handling.
Fixed duplicate planned fee application during repayments
Posting a repayment no longer fails due to planned fees that had already been applied being incorrectly reapplied during repayment processing.
Late repayment fees now correctly reflected in schedules
For certain loan accounts, late repayment fees applied to installments are now correctly reflected in the repayment schedule, preventing end-of-day job failures.
Improved error handling for duplicate loan account IDs
Refinance API V2 now returns the correct DUPLICATE_LOAN_ACCOUNT_ID error instead of INTERNAL_ERROR when a loan account ID already exists.
Enhanced loan account ID generation error messages
Generic errors when loan account ID generation fails now provide more specific error information.
API-only roles can now receive loan termination permissions
Administrators can now grant the Terminate Loan Accounts permission to API-only roles, enabling secure, granular access control for integrations.
Improved error handling for invalid API operations
Fixed an issue where calling GET /loans/{loanAccountId}:previewPayOffAmounts returned a misleading INVALID_LOAN_ACCOUNT_ID error instead of the expected INVALID_API_OPERATION error.
Multi-state loan searches now include repaid accounts
Previously, when searching for loans using the accountSubState filter with multiple values, loans in the repaid sub-state were not included in the results when combined with other sub-states.
Corrected prepayment calculations with optimized payments
We have fixed an issue where making prepayments could lead to an incorrect optimized payment repayment schedule and a higher total repayment amount when INCREASE_LAST_INSTALLMENT late payment calculation settings were used.
Non-customer-facing lending system improvements and internal API optimizations.
Mortgages
Fixed first installment date calculation for month-end schedules
Corrected incorrect first installment date calculations for schedules with installments scheduled on the last day of the month.

Non-customer-facing Islamic banking product configuration and UI improvements.
Deposits
Fixed deposit block deletion with special characters
We fixed a bug that prevented the deletion of a block fund if the externalReferenceId contained certain characters, such as forward slashes, by introducing validation on block creation.
Resolved manual interest application for zero-rate periods
Fixed an issue where manual interest application on accounts with long periods of 0 interest rate tiers generated interest applications for the entire period.
Clients and Groups
Enhanced client search permission enforcement
View Client Details permission is now properly enforced on UI search bar functionality.
Developer
Improved custom field deletion for grouped fields
Fixed an issue where deleting multiple grouped custom fields disrupted the ordering sequence and incorrectly deleted data.
