As you have noticed, some guilds are having issues with LOTROster and Turbine's data feeds since they updated the my.lotro.com website..  This is due to the fact that inactive characters are now archived by Turbine, and any request for their detailed character data returns a "noCharacterData" error, which LOTRoster interprets as a hard failure, and makes it stop processing any further roster entries.

The short term solution for guilds using LOTRoster is to disable the fetching of Extra Data, which will at least let you get a basic roster working (and updating).  In the mean time I have already updated my internal build to gracefully handle this error message, and keep processing the roster, simply not updating the extra data for those archived characters.  I am waiting before releasing it because data.lotro.com should be getting some additional data next week, and I want to see if a) there's anything worth adding to LOTRoster, and b) nothing breaks in LOTRoster (it shouldn't, as I'm properly parsing the XML based on attributes).  Expect 1.3.0 to be available within a week or two at most.

Beside this change, 1.3.0 mostly consists of improved error handling related to data.lotro.com access,  and full support for character levels up to 65 (although the only issue with 1.2.0 is the Guild Chart filter limits queries only up to level 60).

As a reminder, you can subscribe to the RSS feed to be notified whenever new versions are released.  Just click on the orange RSS icon on the LOTRoster download page to subscribe using your favorite RSS reader - I use Mozilla Thunderbird myself.

EDIT: I misread the Turbine developer message.  Turns out the new fields are already published by the feeds, so expect 1.3.0 to be released sooner than first expected.
