+We've updated our {{ this-connection.display_name }} (v{{ this-connection.this-version }}) integration to fix issues during the integration execution: 
+
+- Out-Of-Memory Issue:
+Initially, all records from the start date to the current date were pulled, and the integration allowed generator buffers to grow without limit, surpassing the default extraction memory limits rapidly.
+To address this, we implemented date windowing (default size = 1 day) and pagination for multi-threaded streams, a limited generator buffer growth to finite boundaries and we eliminated performance metrics to reduce performance overheads.
+- Execution Time:
+Previously, to address performance concerns, a single-threaded implementation was adopted, resulting in slow extraction speeds.
+Multi-threaded execution has been reintroduced to expedite historical sync execution with a maximum thread count equal to 20.
+- Data Discrepancy:
+Data discrepancies were reported in certain streams after the extraction gets interrupted due to extraction timeout and memory issue.
+The bookmark strategy has been revised for multi-threaded generators to address data discrepancies.
+We segregated the `LoanAccounts` sub-stream bookmarking to rectify data inconsistencies.

+
+We've improved our {{ this-connection.display_name }} (v{{ this-connection.this-version }}) integration to allow the specification of a string projection, instead of using only integer values. 
+
+For example, the following sample projection now works:
+
+```
+{"name": "$personName"}
+```
