Update my addin from version 7.1 to 7.4

Hello.

I wanna update my extension for LibreOffice7.4.

===========================
I made my extension for LibreOffice 7.1.

After that, I have not touch a addon I developed until now.

Today, I noticed that the extension didn’t work for 7.4.

===========================
What should I do for updating?

Or Is there any documents about this?

===========================
I use eclipse and java for development.
