Based on Debian Bookworm having X11 and Openbox. PostX Gnu/Linux release is likely to happen in next 3 weeks or so.

Have already had their new releases.
Also, I have created a new repository: https://github.com/postman721/PostX
Which for now, has some source materials in it. When release is done, I will also likely release the PostX Gnu/Linux building script. In these days it is good to share. And of course, after more than a decade of Debian I am considering to go ahead and building something else for awhile, maybe OpenSuse derivative is on the horizon. Whatever the future holds, PostX Gnu/Linux will stay active on Debian side and will see an increase on automated builds(currently working on it), which means easier and more predictable times of release.
