+    Starting AltDSS/DSS C-API v0.15.0, the way some properties are handled has been tweaked to try to provide a better experience for general users.
+
+    - The arrays provided in the text interface, scripts or the Alt APIs are required to match the provided sizes. For example, if a LoadShape has `NPts` set to 12 and the user provides 24 values for `PMult`, an error is generated.
+
+    - Some properties in Transformer and AutoTrans that previously silently replaced zeros with default values now error.
+
+    - Some properties are read-only, but previously silent ignored input values. Errors are now generated if the user tries to set them. This includes some properties that are read-only on certain conditions. For example, if a SwtControl is locked, its state cannot be set.
+
+    Set this compatibility flag to silently ignore the errors listed above and restore the original behavior.
