- Highlighting for options (-x, --x) now doesn't strip the prefix (may be whitespace). - Escape sequences are now cross-platform compatible (directly taken by groff/troff [man's renderer]) - Now we check for the section before displaying the man pages. - On MacOS, there is HTTP(n) which is different from our HTTP(1). This used to conflict with it, and we showed the wrong page. Now we specifically ask foir HTTP(1). - Errors that might happen (e.g non executable man command) is now suppressed. So in the worst case (if anything regarding man execution goes wrong), we'll always display the manual. - Docs for man pages. - HTTPie man pages. - Epilog for the man pages (see also) - Auto-generated comments.
