Well, i did some tests with Gnumeric 1.8.0 last weekend and i uploaded the source-tarball of it allready, but short test showed that it is not really stable here, so i did not upload the binary package (the .deb) and the .dsc and .diff.gz files.

The new version also shows the same problems like 1.6.3, but has additional ones. (One point is that it crashes when you try to open the Filechooser a second time.) Another thing i consider really annoying is that the fullscreen-button does not work, except if you have a keyboard connected (I have a Nokia SU-8W Bluetooth Keyboard.)

I could upload the .deb of 1.8.0 as it is currently, but my guess it that you will not like it more than the current version (1.6.3). I will most likely not have time to work on it in the next weeks (at least in the next 4 weeks, maybe longer), so do you really want a version which is worse than the current one?

(I will at least upload the .diff.gz and .dsc files, so someone else who is interested in improving the situation can compile and debug it by himself.)

Edit:
Sources uploaded completely, everything you need to compile it by yourself should be located in my repository (http://people.debian.org/~tschmidt/maemo/chinook/). If some of the build-dependancies are missing, please let me know, i'll upload them as soon as possible.
