Our development team has prepared another **batch of improvements and changes** that accelerate Mergado processes and improve some of the applications. See what news will help you manage your advertising.
## The new Mergado release brings major changes as well as minor adjustments
### Major changes
- We have added **support for block comments in MQL** (product selection query language) in format */\* … comment … \*/*.
- For better protection against accidental deletion, you will now need **a double confirmation** when deleting the online store.
### XML
- We have released validation of element names before the final export of XML feeds — now **it is possible to export parameters whose names end with a colon**.
- **We’ve accelerated the XML import process if the input XML file is valid.**
- Exporting XML files has also undergone slight optimization. On test data, we tracked up to **50% acceleration** in the final data feed export.
### Rules
- The Overwrite in Bulk rule on the right side now tells **values that are already used** on the right.
- For the Rename Categories in Bulk rule, **the names of the input and output elements** for the categories are also displayed on the **Rules** page.
- If a **rule applying process** is in progress for a given export, its **progress** is shown at the top of the page in Mergado — with **a click-through icon for detailed information**. This feature is **in the test phase** and we’re fine-tuning it.
- We **fixed a bug** in the [Biano.cz](https://www.biano.cz/) shipping pricing rule.
### Custom format
- We fixed a bug that occurred when a Custom format was used as **input and output as one export**.
- We fixed a bug when exporting nested elements to a Custom format if more than one was defined for that format.
- For custom formats, parameter and carrier names can now include a vertical character.
