 A macro-processor variable defined without a value will now be equal to `true` (it would previously be equal to `1`).
 
 This affects lines such as:
+
 ```
 @#define var
 ```
+
 in a `.mod` file.
 
 This also affects variable defined on the `dynare` command line, such as:
+
 ```
 dynare myfile.mod -Dvar
 ```
 
 This change should have no impact in most cases, since variable thus defined are typically tested with `@#ifdef`/`@#ifndef` (in which case their value does not matter).
+
+# Changes related to `resid`
+
+The `resid`-command now only accepts the new `non_zero`-option. The old syntax
+
+```
+resid(1);
+```
+
+will trigger an error
+
+> syntax error, unexpected INT_NUMBER, expecting NON_ZERO 
+
+and needs to be replaced by
+
+```
+resid;
+```
