Heh. Ye I had trouble making it all clear.
Currently, the 1706 is only on Ron’s test machine. Quite possibly also on the “subversion server”. I’m not sure if this server is accessible by other people than ron, but it’s probably not useful anyway.
And indeed, the version is released when it’s stable “enough”. They are still “nightly” aka unstable.
So long story short, the newest version is the 1696 so far. The easiest way to find out about newer versions, is to check the RSS feed, as this is where new “stable enough” nightly releases will be posted.
Hope this clears thing up for you.
