More problems fixed, and documentation hopefully complete, here's 0.9pre3 for brave folks to download and test.
The changes list is a lot shorter this time:
Changes since rc2:

  • In the Cacti plugin, the 'add map' list is sorted properly now, like the editor.
  • PHP4-related fixes for plugins. In particular the cactihost DS should set 'state' now.
  • Fixed RRD datasources for Windows users. The result of one fix too many.
  • Fixed editor bug so that you can initially place the DEFAULT legend again
  • Fixed '-' DS name spurious error.
  • Documentation complete! (I think?)
  • Added a new diagram with all the basic "how to change..." info on it

It can be downloaded here and the manual is here too (and also in the zip). Please let me know if you find anything strange!
