FYI...
(09:28:14) >Server Admin: server will shutdown in 1 minute for upgrade
(09:28:28) >Server Admin: SERVER WILL BE UPGRADED TO 0.4.01 RELEASE
(09:28:44) >Server Admin: YOU WILL NEED A NEW CLIENT TO CONNECT TO IT
(09:28:46) >Server Admin: SEE YOU IN THE NEXT RELEASE
And from IRC just now (10:30 Monday "server time", 2:30 utc)...
(09:32:49 PM) XilliX: NO ONE IS SUPPOSED TO LOG ON
(09:32:57 PM) XilliX: give it a rest
(09:33:09 PM) XilliX: if we can get it running we may be able to debug it
(12:20:54 AM) XilliX: everyone can log on as much as they want now
...but note that it sounds like the server is still crashing every couple minutes.
That's "new client" as in "use the updater", not as in "reinstall everything":
No false rumours
Velh: It's quite simple, the updater tool takes your old client, and upgrades it to the "new client"
And in a different thread, we see that it's probably safer to wait for the official announcement:
it'd be safer to not run the updater until it is announced it could be used.
you're probably going to have to re-install now. might as well just wait until the new client packages are released.
Yup. Laanx is crashing during startup because of something, and it can only be fixed when a dev takes a look at it. And that will be tomorrow, some time.
