James D. Callahan III:
    - When scanning a vendor, don't auto-set the VENDOR filter on the recipe if it has the SEASONAL filter.
    - Don't let the scanner complain about missing the VENDOR filter if the SEASONAL filter is set.
    - Removed the VENDOR filter from all Engineering, Leatherworking, and Tailoring recipes which have the SEASONAL filter so they can be toggled off using the "World Events" filter: these recipes will still show under the Vendor category in the Acquisition tab when toggled on.
    - Removed the VENDOR filter from three World Event cooking recipes so they can be toggled off using the World Event filter. They will still show up under the Vendor category within the Acquisition tab when toggled on.
    - When attempting to run a command line scan, check to make sure the profession name is not an empty string.
    - 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.
