Pawn 

Version 1.9.13

Included a variety of updates and improvements to the French translation.

Version 1.9.12

Included the correct version of the French translation (with the changes from 1.9.10, which were accidentally reverted in the 1.9.11 release).

Version 1.9.11

Significant changes to the built-in Wowhead scales. (Note that this iteration doesn't include spell power, attack power, or weapon DPS. This is the design of the Wowhead scales, not a problem with Pawn.)
Lots of further improvements to the Spanish translation.

Version 1.9.10

Fixed a problem where weapon speed was not read properly in Spanish.
Made a few changes to try to make the French version of Pawn understand large numbers (1,000 or greater) better.

Version 1.9.9

Given their exorbitant cost, Pawn will no longer suggest Greater Taladite gems on gear lower than item level 685 (mythic Highmaul).
Fixed the problem where some new Draenor wands caused an error to appear in the chat log and did not have their DPS calculated correctly.
Attempted to fix a problem in Spanish where numbers greater than 1,000 were not read properly.

Version 1.9.8

New scales from Wowhead have been integrated into Pawn, and the starter scales that Pawn previously included have been removed.
Includes a new Spanish translation, which is still a work-in-progress.
Fixed a bug where the socketing advisor would always unhelpfully suggest that you put a gem "of any color" into a prismatic socket.
Fixed a bug where It was difficult or impossible to change the color of a scale, depending on where the Pawn window is situated. (It was difficult if the scale list happened to be behind the color window.)
Fixed a bug where if you opened your chest of Garrison Resources and the last item you won (it showed up in a "you won!" popup) was an upgrade, the Garrison Resources would also show up as an upgrade. (Hey, maybe you got some Complicated Wood instead of Simple Wood.)
Removed the code that dealt with Wrathion's Breath of the Black Prince item, which added sockets to certain weapons, but is no longer obtainable by new players and not relevant to current content.

Version 1.9.7

Strength, Agility, Intellect, and Stamina can't be marked as "unusable" in custom scales. (Since multiple primary stats are on most armor pieces now, marking those as unusable leads to some confusing and unexpected results.)
Made a couple small improvements to the French, German, and Traditional Chinese translations.

Version 1.9.6

Pawn will now no longer suggest gems for items below level 630 (level 100 heroic dungeon). (This change is particularly noticeable for helms, which had high-value meta sockets at level 90, but not at level 100.)
Improved the German and Simplified Chinese translations.

Version 1.9.5

Additional changes to try to prevent the "UseSpecialQuestItem" error from occurring when clicking items in the objectives list.
More improvements to the Simplified Chinese and Traditional Chinese translations.

Version 1.9.4

Dodge and Parry on low-level items will now be treated as if they were Bonus Armor, at a 2:1 ratio. (40 Parry on an item will be treated as 20 Bonus Armor.)
Pawn will now once again work with AtlasLoot even when the "Use GameTooltip" AtlasLoot setting is off. (Release versions only, not the latest AtlasLoot beta.)
The warrior tank starter scale now properly has a value for bonus armor.
Included lots of improvements to the Traditional Chinese translation.

Version 1.9.3

Changed the way that Pawn uses item tooltips, in the hopes that it will prevent issues where the game blocks certain buttons and actions due to "taint."
Fixed a bug where a few settings wouldn't be saved when logging out, including Pawn's list of your best items used for determining upgrades.
Included new French translations.

Version 1.9.2

Continued changes to the starter scales and translations.

Version 1.9.1

Bonus armor is now listed as a separate stat from base armor and can be given a value independently.
Significantly increased the value of armor and bonus armor in the tank starter scales.
Fixed a harmless error where a message about #(Item1.UnknownLines) could appear in the chat log when using the Compare tab.
Fixed a harmless error where a message about being unable to parse the item link could appear in the chat log when hovering over a caged battle pet.

Version 1.9

Updated for WoW 6.0 and Warlords of Draenor. Many features have changed in some way as a result of item changes in patch 6.0.
I updated the visuals for the Pawn UI to be a little more warlordy.
A new set of starter scales have been added for all classes and specs. You can use these scales as you would the old Wowhead scales, and you can also customize them to your heart's content.
The Wowhead scales have been disabled since they haven't been updated for patch 6.0 and would do more harm than good.
The values of Pawn's default scale have changed to be a more appropriate starting point for WoW 6.0.
New stats are recognized and can be assigned values on the Values tab: Bonus Armor, Multistrike, Versatility, Movement Speed, Leech, Avoidance, Indestructible.
Obsolete stats (hit, etc.) are removed from your scales upon logging in, and have been removed from the UI.
All of the new Taladite gems in Warlords of Draenor are now in Pawn's database.
The changes to stats on pre-Draenor gems in Pawn's database have been taken into account for purposes of gem recommendations. (I anticipate that I'll need to do another update of gem stats before the expansion hits.)
A new option has been added, on by default: "Ignore sockets on low-level items." When this option is enabled, Pawn will ignore sockets when calculating values of low-level items (currently, any item below level 463), so they won't have inflated values when Pawn determines upgrades.
Pawn's calculations for item values no longer take reforging potential into account since that feature is gone from the game.
All code for Pawn's Reforge Advisor feature has been removed.
Changed the way that information about your best items for purposes of determining upgrades is stored and processed. (I now use item links instead of item IDs, since in Warlords of Draenor, a mythic version of one item and the raid finder version of the same item might have the same ID but a different bonus suffix.)
