Documentation

What to do upon closing a tab on the tab line.

If bury-buffer, put the tab's buffer at the end of the list of all buffers, which effectively hides the buffer's tab from the tab line. If kill-buffer, kills the tab's buffer. When a function, it is called with the tab as its argument. This option is useful when tab-line-tabs-function has the value tab-line-tabs-window-buffers or tab-line-tabs-fixed-window-buffers.

This variable was added, or its default value changed, in Emacs 27.1.
