1.23 is definitely a quantum leap forward from 1.22.4. There's a lot to digest! > Secondly I have switched from groff 1.22.4 to groff 1.23.0rc3. > However, the layout is now broken, as some of .sp and .bp in my document are > ignored in the newer version. > I do not see in man groff_ms any macros for page break or vertical space. > I am attaching a little reproducer. The missing page break you're seeing here is due to a combination of factors: - Immediately before the .bp, you call the .DE macro - The .DE macro was recently modified to invoke the .ns request. - When no-space mode (.ns) is in effect, a .bp is ignored. (This is long-established roff behavior.) The .ns request was added to .DE to address a rendering issue with multiple displays in a row. (See http://savannah.gnu.org/bugs/?62688 for the full story.) Your case appears to be an unintended side effect. The simplest solution is to turn off no-space mode yourself (using the .rs request) before the call to .bp. A more general solution for you might be to write your own simple new-page macro that always does this for you: .de BP .rs .bp .. I'll let Branden address whether his 62688 fix should be tweaked to account for this.
