FEATURES
-- Logs all quests that a player receives and records them in a sortable in-game list
-- The user can customize what data the addon logs. Using the default options records the following information for each quest:
-- -- Quest title, objectives, rewards, items as shown in the normal QuestLog
-- -- NPCs giving and completing the quest
-- -- Location of player when quest was accepted/completed
-- -- Level of player when quest was accepted/completed
-- -- Played time of player when quest was accepted/completed (displayed in days:hours:minutes:seconds format)
-- -- Times quest has been abandoned/failed
-- -- XP rewarded for quest completion
-- -- Money rewarded for quest completion
-- Notes can be added to quests
-- Quests can be edited and deleted
-- Quests can be manually added
-- Only records quest data from the time the addon is first used
-- Does not modify any of the game's original files

VERSION HISTORY

v20000-1
-- Updated for Patch 20000 by Raleran.
-- Fixed frame problems.
-- IMPORTANT NOTE: You MUST update your QuestHistory.lua (SavedVariables) file for this version of QuestHistory to work properly with your old data! Please get the QH_Fix tool from http://www.getemerald.com/QuestHistory.php

v10900-1
-- Added MetaMap support (as alternative to MapNotes).
-- Fixed background graphic display issues (thanks to blankstare2@Curse)
-- Added slash-command to enable/disable Quest Level display at NPC's. Type /qh levels to toggle.
-- Forced current realm's characters to sort to top of the dropdown list.
-- Fixed error that occurred with the dropdown list when you had a large number of characters on various servers.
-- Changed version structure to match other projects.
-- Updated for Patch 10900.

v2.8
-- Added quest level display to Quest Selection window at NPC's. Only occurs when there's more than one quest available.

v2.72
-- Changed the WorldMap cycler to the zoning event, so hopefully the Blizzard 0,0 bug will be killed PRIOR to any Quest activity.
-- Removed the circuit that was getting people stuck on quests in instances.
-- Increased individual quest-accept delay to 1 second. This may not be long enough. Let me know!

v2.71
-- Removed the 0,0 traps, as I've only received reports of 0,0's inside instances since adding the traps. Since instances are ALWAYS going to be 0,0, we are going to assume that things are kosher at the moment.

v2.7
-- Changed Unknown Entity search string to a localized global (so all languages should be covered) (courtesy Asjaskan@Curse)
-- Now strips any third-party quest level-adding addon text from the titles (courtesy Asjaskan@Curse)
-- Added new trap for 0,0 coordinate bug.
-- Added possible 0,0 fix, using a WorldMap show/hide cycler.
-- Finally fixed the delay on subsequent accepted quests (speed-accept bug).
-- Fixed errors that occurred upon login if you weren't an existing QH user.
-- Updated to TOC 1800.

v2.6
-- Fixed Unknown Entity bug (more like, plague).
-- Added Unknown Entity checks/fixes to the login procedure, and to the Repair module.
-- Updated for Patch 1700.
