Version 1.5.19

    Non-caster classes will no longer have off-hand frill items suggested as upgrades to their off-hand weapon by default (in the Wowhead scales), even if the secondary stats are better, because this almost certainly just means that they aren't dual-wielding, not that the item is actually useful.
    Fixed a minor issue where conflicts with other addons could sometimes cause an error when trying to calculate the average equipped item level of a player you're inspecting.  (Pawn still can't calculate the item level in these cases, but it won't cause an error or display inaccurate information.)
    Updated the default Wowhead stat values for warriors.

Version 1.5.18

    Fixed a bug in the average item level calculation for Fury warriors who use two two-handed weapons.
    Added Pawn annotations to the tooltips that appear in the "You are not eligible for these items" window that appears when you kill bosses a second time in Raid Finder runs, so you'll know how sad you should be that that axe finally dropped when you can't roll on it.

Version 1.5.17

    You can now once again see someone's average equipped item level by hovering over the Pawn button on the inspect window.  (Your own equipped item level is now in the General section of your stats list, even without Pawn installed.)
    Fixed a long-standing issue where hovering over the Pawn button on the inspect window could display inaccurate (too low) totals and average item levels if the server hadn't sent your computer the stats for one or more of the items the inspected player was wearing yet.  (Now you know that when you hover over someone at level 85 and see that their average item level is 145, you know that they really are that much of a n00b and it's not just a miscalculation.)

Version 1.5.16

    Items found in the Raid Finder versions of the Dragon Soul raid will no longer appear with an unnecessary (?) icon.

Version 1.5.15

    When you delete a character and then create a new character with the same name but a different class, Pawn will now automatically hide the Wowhead scales from the old class and show the Wowhead scales for the new class.
    Corrected the display of the item you're upgrading in the loot upgrade advisor.  (Since 4.2 it would say things like "25% upgrade vs. ff00ff00Your Old Item".)

Version 1.5.14

    Added in the new epic gems available in WoW patch 4.3.  (You can't see them when you're on a 4.2 realm.)
    Corrected a few calculation errors for Guardian's Demonseye, Jagged Dream Emerald, and Lightning Jasper.
    Hid the equipped average item level information from the Pawn tooltip when on WoW 4.3 since that's now available on the character sheet without needing Pawn.

Version 1.5.13

    Fixed a bug where the value of the stats portion of meta sockets ("Meta: stats") was being drastically overvalued (the "Meta: effect" value was being included as well).
    Fixed a bug where it wasn't possible to manually override a value for prismatic sockets.
    Possibly worked around an error that some people were receiving ("attempt to index field 'UnenchantedStats' (a nil value)") that may have been related to Enchantrix or tekKompare.  (I'm not sure because I was never able to reproduce it myself.)

Version 1.5.12

    Added updated Wowhead scales for all classes and specs, significantly updated for patch 4.2.  (For example, the new scales for plate tanks no longer include agility.)

Version 1.5.11

    Added Pawn tooltip support to the encounter journal loot lists in patch 4.2.  (This doesn't add upgrade arrows next to the items yet; the upgrade arrows will be on the tooltips themselves.)
    Removed the unnecessary (?) that appeared on honor and conquest gear next to "Season 9".

Version 1.5.10

    Fixed a bug where one-handed caster weapons (not main hand weapons; pretty much just Amani Scepter of Rites) would show up as massive upgrades for your off-hand slot even though you couldn't actually put the item there.

Version 1.5.9

    Items that bind to your Battle.net account will no longer get (?) icons on them.

Version 1.5.8

    Fixed an issue where Fierce Ember Topaz would be improperly suggested or not suggested for socketing.  (Calculations were still correct.)
    Added support for the three new Shadowspirit Diamond cuts that were added in patch 4.0.6.
    Fixed a bug where the Gems tab would not show any gems if you were level 81+ didn't have two primary professions (wtf).

Version 1.5.7

    * Upgrades that are less than half of a percent better than your current gear will no longer be shown as upgrades.
    * Fixed an annoying bug in 1.5.6 that was causing some people to get a lot of errors ("attempt to compare number with nil") and was causing upgrade tracking features to not work properly for rings.
    * Fixed a bug that would occur when hovering over the Pawn button on your character sheet if your computer hadn't downloaded information about your equipped items yet.
    * Fixed an issue with a couple Nightstones being improperly suggested for socketing.  (Calculations involving those gems were still correct.)

Version 1.5.6

    * I added back a "Show both current and base values" option since some people just couldn't live without it.  (...you whiners. :)
    * Pawn's now smarter about what it considers as upgrades for heirloom items.  Heirloom weapons currently scale from level 1 to 80, so when you're level 1 to 79, Pawn won't consider other weapons to be upgrades, but when you hit level 80 it will start suggesting upgrades again.  Heirloom chests currently scale from level 1 to 80 so Pawn will work similarly, but they give an XP boost until you hit level 81, so Pawn won't start suggesting upgrades for your chest until you hit level 81.  Once you hit the level cap (85 if you have Cataclysm) then it will ignore heirloom-ness for purposes of tracking upgrades.
    * Updated the Wowhead stat weights for all warrior specs, holy and protection paladin, marksman hunter, holy priest, elemental shaman, all mage specs, and balance and resto druid.

Version 1.5.5

    * Added a new per-scale option (on by default) that causes Pawn to never consider armor that your class doesn't specialize in as an upgrade after your character hits level 50.  (For example, with the option on, a holy paladin wearing crappy quest green plate that sees the most awesome epic mail healing pants evar will still not see that item as an upgrade since it would break the +5% intellect bonus for wearing only plate.)  To change this option, go to the Values tab, choose a scale, scroll down to the list or armor types and click one, and then check the option that appears.
    * Added new options to disable each of the Pawn advisors (loot upgrade advisor, quest upgrade advisor, socketing advisor, and reforging advisor) individually.
    * Added a new option to no longer color the borders of tooltips for items that are upgrades.  (This is useful if you also use TipTac or just really don't like that feature.)
    * Added proper support for items with prismatic sockets (which will no longer appear in the UI as red sockets) and cogwheel sockets (which were previously ignored).
    * The best cogwheels for each of your scales will now be listed on the Gems tab when you're on an engineer of level 81 or higher.
    * Included a bunch of new patch-4.0-friendly scales from Wowhead.
    * The "show current item values" and "show base item values" options are now gone.  Base values are always shown, and current values are never shown.
          o The code for calculating current values is still present, but I plan on removing it in a future version.  If you really NEED that feature, you should try to change my mind soon.
    * The Pawn UI now closes when you press the Escape key.
    * Hovering over the Pawn button on your character sheet will now list both the average item level of your gear as well as the "epic item level" that it did in the past.  Pawn's epic item level number factors item rarity into the value; the average item level ignores the rarity of the item and will yield numbers that are more comparable to the ones you see in-game, such as the Looking for Dungeon interface.
    * Fixed a bug where the socket values for Wowhead scales that aren't visible on your character's tooltips (such as the ones for other classes) were getting socket values calculated that were far too low.
    * Fixed a bug where exported scales didn't include the quality of meta gems to use.
    * Fixed a bug where item recipes taught by a profession trainer would have unnecessary (?) annotations.
    * Fixed a minor display issue that occurred in the Loot Upgrade Advisor when a massive upgrade dropped in a dungeon run.

Version 1.5.4

    * The Quest Upgrade Advisor will now put a question mark (?) icon on trinkets.
    * You can now show and hide scales by shift-clicking on their name in the scale list.  (Maybe this will help all those people who can't seem to find the "show scale in tooltips" checkbox...)
    * Added support for the dodge rating on the new Cataclysm head enchantment for tanks.
    * When you copy a built-in (Wowhead) scale, the built-in scale will now be automatically hidden.
    * Fixed a bug where if you right-click an NPC who has a quest with some items you've never seen before and some that you have, Pawn would sometimes display incorrect upgrade/vendor information.  (Unfortunately, this happens a lot when leveling.)
    * Fixed a bug where some reforged items were getting a few extra points in their values for their reforging potential, which shouldn't happen since you can't reforge an item a second time without restoring the original item first.
    * Updated stat weights from Wowhead for some rogue, death knight, and shaman specs have been included.
    * Added more detail to the "Show item IDs" option, which isn't too useful to most people.

Version 1.5.3

    * Fixed a nasty bug where sometimes hotkeyed spells and abilities would stop working after using the reforging or item socketing UI.
    * The Wowhead scales for rogues will now ignore upgrades for two-handed weapons (which would just be fishing poles).

Version 1.5.2

    * You can now set Pawn to hide upgrades for your one-handed weapon set and your two-handed weapon on a per-scale basis.  To change this setting, go to the Values tab, select the scale you want to modify, and then find either a one-handed or two-handed weapon in the list of weapon types, and the new option will appear.  (The option will not be visible for weapon types that you cannot equip, such as daggers for paladins.)
          o For example, even though paladin tanks can use two-handed weapons, a two-handed weapon is never an "upgrade" for a paladin tanking set, so you can turn off upgrade notifications for them.  Similarly, retribution paladins can use one-handed weapons, but they are never upgrades.
    * The amount by which you can increase an item's score through reforging is now shown on the Compare tab as "Reforge potential," and is now automatically added to the score of an item.
          o This is consistent with how Pawn treats empty sockets—the assumption is that if you care about the item you will gem and reforge it properly.
    * Added a new stat, "Off-hand frill," which applies to all "held in off hand" caster items, and not off-hand weapons.
    * The Compare tab will now also show the percentage increase in the score of the better item in addition to the score difference.
    * Cloaks will no longer be counted as cloth items, so scales that have "items with this are unusable" set for cloth armor will now get values for cloaks.
    * Fixed a bug where the item link window could have a green border when it shouldn't.
    * Fixed an error that could sometimes occur when adding off-hand items to the Compare tab using keyboard shortcuts.
    * Low-level items with elemental spell damage ("of Fiery Wrath" and so on) will now be treated as if they had spell power, rather than having a specific unique stat.

Version 1.5.1

    * Added the Reforging Advisor, which suggests the way to modify an item that will maximize its value when you're visiting an Arcane Reforger.
          o Be careful when reforging hit rating and expertise; if you adjust your scales to reduce the value of those stats when you're at or near the cap, Pawn will determine that the item's value would be maximized if you reforged the hit or expertise into something else, which may take you below the cap.
    * Cataclysm gem cuts are now available on the Gems tab, including many that weren't available in beta.  To update your scales to use the new gems, just select them from the lists on the Gems tab.  (This is a per-scale setting.)
    * The upgrade annotations on weapons will now show which weapon set (1H or 2H) the item is upgrading so it's more clear that, for example, some random green dagger isn't better than Shadowmourne; it's just better than your skinning knife.
    * Prismatic sockets on relic items will now get a proper value.  (Pawn will treat them as red sockets, but since there are no socket bonuses, it won't really matter—Pawn will assume that you will socket the best gem of any color when calculating the value.)
    * If any of the reward choices for a quest is a trinket, Pawn will now never show the coins (highest vendor price) icon on any item for that quest so you aren't as likely to accidentally take a useless item if there's a nice trinket available.

Version 1.5

    * Pawn now tells you when an item you're looking at is an upgrade to your current best gear for a particular scale.
          o Pawn scans your equipped items and all of your Equipment Manager sets to find your best items for each of your scales.
          o Tooltips of items that are better than the best item of the same type will get an upgrade icon and have an upgrade percentage listed.
                + Trinkets are ignored since they have special effects that Pawn can't value that drastically affect their usefulness.
                + For rings, items that are better than your second-best ring will be shown as an upgrade.
                + Items can be an upgrade for multiple scales simultaneously.  For example, if you had a "healing throughput" scale and a "healing regen" scale, a nice new healing weapon might be better than your current weapon for both of those scales.
          o You can easily compare items against your current best-in-slot items using new buttons added to the Compare tab.
          o Pawn currently assumes that you'll want to keep a two-hander around as well as two one-handers, so upgrades for either set are handled independently.  This can create some odd situations; for example, a shaman with no interest in two-handed weapons at all will see most two-handed weapons as a potential upgrade.
                + If you want to avoid this, you can set the two-handed weapon stats ("Axe: 2H," "Polearm," etc.) to Ignored on the Values tab for your scale(s).  You can't make changes to the built-in Wowhead scales directly, so you'd have to make a copy of the scale first, hide the Wowhead one, and then modify your copy.  I'll look into ways of making this less stupid in future versions.
          o The new upgrade features can be turned off entirely from the Options tab if you find them annoying.
          o Added the Quest Upgrade Advisor, which adds an arrow icon next to quest rewards that are upgrades for you, or if none of the rewards are good, adds a coins icon next to the reward that will vendor for the most money.
          o Added the Loot Upgrade Advisor, which adds a popup window next to the roll window when an item drops that is an upgrade for you.
    * The default behavior has changed so that Pawn only modifies tooltips of items that are upgrades.  Existing Pawn users will probably want to change the "Show upgrades on tooltips" option to "Show scale values and upgrade %."
    * Fixed a problem that appeared in patch 4.0.3 where haste and resilience rating on items was not being recognized.
    * Quest rewards shown on the world map will now have Pawn values shown on them.
    * "Currently equipped" tooltips attached to the item link window will now have Pawn values shown on them.
    * Added a new "stat" for all off-hand weapons.  The Wowhead scales for specs that can't use off-hand weapons have that stat ignored.
    * Fixed a bug in Pawn's item score cache that was causing unnecessary slowdowns when Pawn needed to calculate several values at once, such as when hovering over the Pawn button on your character sheet, or when "currently equipped" tooltips are visible.
    * Scales can no longer mark the weapon speed "stat" as ignored.
    * Updated the Wowhead scales to add a placeholder value for mastery rating.
    * Updated the value of spirit in the Wowhead shadow priest scale to the levels of hit rating due to the Twisted Faith talent.

Known issues in this version

    * The Loot Upgrade Advisor is currently not showing up in all cases that it should.  However, even when it's not working, you can still hover over the item's icon, and upgrades will still be appropriately marked in the tooltip.  Please don't pass on items that you need just because the upgrade advisor didn't pop up.  :)
    * The Quest Upgrade Advisor is not currently compatible with some quest log addons, such as QuestGuru.
