James D. Callahan III:
    - MOAR cleanup!
    - Removed duplicate change log entry (was already added for 2.2.8 and then added again for the development version).
    - Cleanup for PrintScanResults()
    - Cleanup.
    - Added Gizzik Oregrab to the localizations.
    - Added Nerog as a trainer to three Inscription recipes.
    - Added "Gizzik Oregrab" to the Smelting trainers DB.
    - Fix for scanning trainers which do not exist in the database.
    - Minor cleanup and fixed ticket #1266.
    - Replaced some Print() calls with Debug() calls
    - Cleaned up missing library detection and re-located it to OnInitialize() so the player will actually see the messages.
John Pasula:
    - Fix issue for smelting.
    - Update changelog.
    - Add support for ptBR.
mike:
    - Fix a variable name that Torhal mistakenly overlooked when uppercasing all the private constants, in turn it broke searching
John Pasula:
    - Fix a typo that I didn't put in for a change.
James D. Callahan III:
    - Converted the remaining constant names to uppercase.
    - Recipe state flags are now declared file-local in Recipe.lua
    - Uppercase some private constants (more later).
    - Overhaul/standardization for profession names.
    - More re-organization.
    - Cleaned up and reorganized the code for the lookup lists.
    - No longer to remove recipe states when the panel is hidden since this is done for every profession Scan.
    - Every time a profession is scanned, remove the KNOWN, RELEVANT, VISIBLE, and LINKED states from all of its recipes. This allows one to browse through Guild professions accurately.
    - Added private.profession_recipe_list so recipes from specific professions are easier to deal with.
    - Renamed private.num_recipes to private.num_profession_recipes
    - Moved declaration of private.recipe_list from Core.lua to Recipe.lua
John Pasula:
    - Revert last commit.  Having it in Discovery and World Drop just looked silly.  Playing around with leaving the World Drop flag active for it however.
    - Playing around with world drop for book of glyph mastery to see how it looks.  Single test case right now.
    - Switch the Northrend zone tag from Northrend Research to the Book of Glyph Mastery.  Research can occur anywhere you want, the books only come from northrend type mobs.
mike:
    - Update the Vendor: Qia's location
    - Added Northrend as a location for the DISCOVERY_INSC_NORTHREND discovery phrase so that the recipes will show in the location tab as well
James D. Callahan III:
    - Use proper variable name ("entry" versus "t")
    - Define NO_LOCATION_LISTS inside of private:AddListEntry() if it hasn't already been defined - fixes error of assigning values which do not yet exist.
    - Do not require a location for Discovery recipes.
    - Allow Discovery recipes to be searched.
    - Added toast to notify of new debug messages if using tekDebug.
    - Added LibToast-1.0
    - Added support for Discoveries to the recipe dump.
