# Version 5.8.0.x

**Introduction of null constant - **Since the concept of a null constant has been introduced in version 5.8.0+, any variables that may have been named ‘null' or ‘nil’ will cause an error since those are now reserved keywords for the language.

**Introduction of integer type** - Due to the introduction of the integer type some values that were intended as numbers will be automatically interpreted as integers. This could cause the results of a calculation to loose  all decimal values or cause the result of the calculation to change due to rounding differences.

```
return 3/2;
```

In older SIL, the result would have been 1.5. In the new SIL, the result is 1, because the literals 3 & 2 are now integers. In order to maintain the same results the code must be changed like in the examples below:

```
return 3.0/2.0;

//or, explicity declare the type

number x = 3;
number y = 2;
return x/y;
```

The introduction of the integer type has also the following consequence:

```
try {
   .....
   if( ... ) {
    throw 1; //integer!
   }
   if( .... ) {
    throw 2; //these are integers literals now
   }
} catch integer i {
  //you need to add this block in order to deal with the above throws
} catch number n {
  //you need to move code from here in the above block!
}
```


**Packages - **We added package and the “use“ keyword, please consider “use“ and “package“ keywords as inappropriate for variable names ('package' may be used in the future)
