@ -71,6 +71,16 @@ I wanted to make code that could be used for people who are just getting started
There will always be more work to do here. ;-)
#### Updates
##### v0.47 1/7/15 by DW
Fixed first time startup problem creating prefs.json and stats.json.
Also, we now make sure the *domains* folder exists at startup.
Fixed a problem in handling requests if you specified a different folder for PagePark to serve from.
#### Questions, comments?
Please post a note on the <a href="https://groups.google.com/forum/#!forum/server-snacks">Server Snacks</a> mail list.
