How do I update PlantUML?

How do I find out which version of PlantUML is installed?
How do I update PlantUML?

Used by: Windows 10

I have PlantUML installed.
I look at diagrams using Notepad++ and other applications.
I want:
- find out which version of PlantUML is installed;
- update PlantUML.

I've studied the links
https://plantuml.com/ru/download
https://plantuml.com/ru/starting


Update1

I have completed:
```
@startuml
version
@enduml

```

I'm getting a message:
```
PlantUML version 1.2025.4beta2 (Unknown compile time)
(GPL source distribution)
Dot version: dot - graphviz version 10.0.1 (20240210.2158)
Installation seems 0K. File generation 0K
Java Runtime: OpenJDK Runtime Environment
JVM: OpenJDK 64-Bit server VM
Default Encoding: UTF-8
Language: en
country: US
4096

```

At the command prompt, I executed `java -version`:
```
C:\Users\Root>java -version
```

Result:
```
openjdk version "11.0.16.1" 2022-08-12 LTS
OpenJDK Runtime Environment Microsoft-40648 (build 11.0.16.1+1-LTS)
OpenJDK 64-Bit Server VM Microsoft-40648 (build 11.0.16.1+1-LTS, mixed mode)

```

But I have a question: to update PlantUML, what should I do?

I need the latest versions:
- Java;
- GraphViz;
- plantuml.jar;

Did I understand correctly?
Or is it all self-updating?
