Question: What is the latest version of iText? And what is the maven dependency for that?

Answer: 
As with many (any?) open-source library, their website contains a changelog. iText's one can be found [here](https://itextpdf.com/posts/changelog).

And as of today, the latest version is ~~[5.5.9](https://itextpdf.com/posts/changelog/559)~~ [7.0.0](https://developers.itextpdf.com/itext-7-java).

The dependency for version 5.5.9 would be 

```
<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>itextpdf</artifactId>
    <version>5.5.9</version>
</dependency>

```
```
This was the latest release as of today

<!-- http://mvnrepository.com/artifact/com.itextpdf/itextpdf -->

<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.5.9</version>
</dependency>

```
