# v0.15.0 - Default Value, Forward Slash and more!

### ✨ New

* You can provide a default value in the column. You can use provided macros like `null`, `undefined`, `[]`, `true` and `false`. Or you can mention a value of your choice. Which will reflect in response when the column value is empty or undefined.

### ➕ Improved

* You can provide a key for `Handsontable` dynamically from environment variables while self-hosting. By default, the impler uses the trial license key.

### 🔧 Fixed

* The error mapping was not working properly if the column key contains `/`. Now you can use it without any hesitations.
* The import widget was not able to manage the data count properly due to an incorrect API response.
* Backspace on any cell in the import widget was showing `null`.
