This version offers a better experience for users
who want to modify the output, since they can hack
XSLT instead of hacking the C code. Actually, only
a few commands have been replaced by XSLT
transformations: texreport, txtreport, htmlreport,
weekly_txt, weekly_tex, and weekly_html.
This release contains some new properties to control the Gantt graph. It is now possible to show past days (with a progression bar) and show vacation days.
