Here's a brief overwiew of the changes during the last weeks:
Now RSS feeds seem to work - at least they work on my computer and I received no complaint from other users :)
Some small bugs have been fixed (eg. domain names with extended status and no nameserver) which were detected as expiring are not; and now won't appear as expiring.
When all daily checks have been done, SaveSpell tries to find available not registered domain names in some word lists (names, 3 characters, geography and english words at the moment). Also, from now, in case of load or network errors while daemon in charge of checking the domain names is running, it will just sleep for 5 minutes and retry its task.
In addition, some basic documentation has been written.
