Page Builder CK and Joomla upgrade J3 to J4

I built a very bulky website in Joomla 3, with hundreds of pages with the beautiful Page Builder CK program.
At the end of August 2023, I am required to update Joomla 4.
Now I wonder if those hundreds of pages I built in Page Builder CK (version J3) will soon be editable with version J4.

After all, Page Builder CK has been offering 2 versions for download for some time: for J3 and J4. Are the files interchangeable?

Hi
Page Builder CK is compatible with Joomla 4 since long
for the files, they are the same, you can simply check the version. I have 2 sections in the download area so that users easily know what to download. One day, I will stop the Joomla 3 compatibility
