James D. Callahan III:
    - World Drop entries which are expanded will now show the level range of the mobs the recipe can be found on.
    - Added a few small things I missed when adding the Discovery category.
    - Added a "Discovery" category under the Acquisition tab - currently, only Alchemy recipes are listed there.
    - Changed the Achievement description text to use the Achievement color instead of the Custom color.
    - Build private.faction_ids from private.faction_strings
    - Build private.rep_levels from private.rep_level_strings
    - Build private.acquire_types from private.acquire_strings
    - Build private.item_qualities from private.item_quality_names
    - Build private.game_versions from private.game_version_names
    - Build private.filter_ids from private.filter_strings
    - Renamed private.filter_flags to private.filter_ids since that's actually what they are. Removed unused declarations.
    - Localization and syntax fix.
John Pasula:
    - Research -> Discovery
    - Some minor changes, trying to add a new 'research' category for Alchemy and Inscription.
mike:
    - cleanup
    - Update NPCID for "Pratt McGrubben"
    - Update NPCID for "Harlown Darkweave"
    - Removed the vendor "Brienna Starglow" because she's a regular NPC now ... and "Azure Silk Cloak" is only initially obtainable by Horde since around 4.0.x
John Pasula:
    - Fix an invalid link.
James D. Callahan III:
    - Changed some code formatting to tell the world that Ackis was a lying bastard in that last commit message.
John Pasula:
    - Fix a bug that Torhal introduced.  Tsk tsk.
    - Change ARCH_DROP to ARCH_DROP_ULD and add a location of Uldum so recipes like that appear in the location tab.
    - Revert last change.  Something whacky is going on.  I blame Pompy.
    - Lets test to see if existing code can add locations for custom entries.
James D. Callahan III:
    - Improved the improvement (ensure that entries are nil in cases where a trade skill is dropped in favor of another).
    - Improved logic for storing trade skill links. Fixes ticket 1303.
    - Fixed some silliness I added the last push; fixes ticket 1302.
    - When switching professions via the switcher button, simply grab the scan button's parent instead of performing checks for the existence of various AddOns.
    - Remove an unnecessary check and manual Scan button hide.
    - Consolidate the creation of the Scan button and the setting of its parent frame into a single place, which now happens the first time TRADE_SKILL_SHOW is fired instead of OnEnable().
    - If using Skillet, set the trade_frame to Skillet.tradeSkillFrame so the universe doesn't go pear-shaped.
    - De-yuckification (fix the previous fix).
John Pasula:
    - Check to see if the buttons exist before trying to get their offsets.  Should fix the error when you don't have both professions learned.
James D. Callahan III:
    - Only try to grab an icon texture if the recipe has a crafted_item_id
    - Display the icon for the crafted item in the tooltip, if available.
    - Grab some globals from the unvalued _G.
    - More readability re-formatting.
    - Re-formatting for readability.
    - Use ipairs instead of pairs since this is an indexed table.
    - Cleanup for the new specialties code.
    - Code cleanups and removal of unnecessary comments.
John Pasula:
    - Update changelog.
    - Remove outdated spec. code.
    - Dry-code fix,
    - Dry-coded fix for the specialty issue.  Apparently since 4.x we haven't been filtering specialties properly.
    - Update changelog.
