James D. Callahan III:
    - There is now an AddOn-centric tooltip mode - Middle-click to toggle.
    - In Spamalyzer:UpdateTooltip(): Cancel timers.tooltip_update then nil it out instead of simply calling CancelAllTimers(). Also, in the case of a nil tooltip, set LDB_anchor and elapsed_line to nil.
    - In Spamalyzer:StoreMessage(): If not tracking this message type, and there is no output_frame, abort immediately.
    - In Spamalyzer:StoreMessage(): Don't try to assign a class to a player who is already known.
    - In data_obj.OnEnter(): Check for timers.tooltip_update before drawing the tooltip or scheduling the tooltip update timer.
    - Changed/added some comments.
    - Renamed SetElapsedLine() to Spamalyzer:UpdateElapsed(), made it abort if the tooltip is nil, and replaced its use in Spamalyzer:UpdateTooltip() with a one-second repeating timer in the data_obj's OnEnter.
    - Renamed Spamalyzer:UpdateGuildInfo() to Spamalyzer:GUILD_ROSTER_UPDATE() - also, added nilling of timers on Spamalyzer:OnDisable().
    - Renamed StoreMessage() to Spamalyzer:StoreMessage().
    - Added "track_cache" table so as to not call string.lower() for every call of StoreMessage()
    - Moved all timers to the new "timers" table and changed firing time for Spamalyzer:OnMessageUpdate() from 0.5 seconds to 1.5 seconds.
    - Renamed "guild_members" to "guild_classes", and changed GetPlayerClass() to do a guild lookup before calling UnitClass().
    - Moved defaults table into Spamalyzer:OnInitialize()
unknown:
    - added Battleground General
