I have extensively edited this free haggadah since last year. New to this version are hundreds of corrections, the inclusion of only fonts which can be legally redistributed, and a wider layout intended for legal size paper.
Here is a PDF of the haggadah: Haggadah_Legal.pdf
Here is a zip file containing the fonts used: Haggadah_Fonts.zip
If you want to work on the haggadah, you should first install the fonts, then open the odt in LibreOffice (version 3.6.4). This is the only method (almost) certain to work.
When I first began work on it, there wasn't this glut of Chabad Haggadahs that currently saturates the market. Still, I think this is a valuable contribution in that it provides the complete hebrew text and a translation for free, in every sense of the word.
It is forbidden to use any electronic copy of this haggadah in violation of the strictures of any Jewish holiday.
