From WoW: IncGamers World of Warcraft Wiki

The history of the changes made to the Rogue class during the beta and beyond are detailed below with the most recent at the top.

Patch 1.9.3 (7 February 2006)

• Deadly Poison V - The charges were inadvertently not increased with the new rank of the ability. Increased from 105 to 120 charges.
• Slice and Dice - This ability should no longer miss.

Patch 1.9.0 (3 January 2006)

• Sword Specialization - Special attacks such as Sinister Strike, and Mortal Strike now properly trigger the chance to gain an extra attack.
• Mace Specialization - The stun effect's duration no longer diminishes or is diminished by controlled stun abilities and spells (e.g. Cheap Shot, Hammer of Justice, Charge etc...).
• Slice and Dice - This finisher can now trigger the Ruthlessness talent.

Patch 1.8.0 (11 October 2005)

• Vanish - Fixed a bug where the Chilled effect caused by Ice Armor/Frost Armor was not removed properly when vanishing.
• Parry - Minimum level to train this ability has been lowered to 12.
• Shoot Bow/Crossbow/Gun - Fixed a bug where these abilities could be used faster than intended.
• Throw - Use of this ability will now only cause a cooldown with Shoot abilities.
• Ambush - Now uses normalized attack power.
• Backstab - Now uses normalized attack power.
• Riposte - Now properly sets its cooldown.
• Sinister Strike - Now uses normalized attack power.
• Instant Attacks
  • The mechanics of most instant melee attacks have been modified to improve item balance. Previously, instant melee attacks did damage based on the damage range of the weapon, plus a bonus for the player's attack power. This bonus was then multiplied by the speed of the weapon. As a result, slow weapons did more damage than was intended, and fast weapons were considered inferior by most players. We have changed the way the attack power bonus is calculated for instant attacks. This change does NOT affect attack power calculations for normal melee attacks. Instead of multiplying by the speed of the weapon, the attack power bonus is now multiplied by a fixed number pulled from the following table:
    • Two-handed weapons: 3.3
    • Daggers: 1.7
    • All other one-handed weapons: 2.4
  • As a direct result of this, many weapons have shifted position in their relative power. In particular, many Epic (purple) quality items are now more powerful than slower Superior (blue) weapons.
  • This change was not made to reduce the power of instant attacks, but to correct the relative imbalance of weapon itemization. At a given level requirement, epic quality weapons should always be more powerful than superior quality weapons.
  • Please also note that all normal weapon swings will be completely unaffected by this change. The following abilities are affected by the design change: Sinister Strike, Ambush and Backstab.

Patch 1.7.0 (13 September 2005)

• Riposte - Will now initiate combat when used.
• Deflection - Will now increase parry chance when using Fist Weapons.
• Mace Specialization - The stun effect can now be resisted.
• Shoot Bow/Gun/Crossbow - Should no longer cause a global cooldown on all other abilities.
• The fire damage from the Blazefury Medallion and the Gutgore Ripper's effect should no longer immediately break Gouge.
• Riposte - Fixed a bug where the ability was not usable when a special attack (e.g. Gouge) is parried.
• A level 50 class quest has been added for the Rogue (Lord Ravenholdt in Ravenholdt Manor).

Patch 1.6.0 (12 July 2005)

• Riposte - Targets immune to disarm effects will now take damage from Riposte.
• Disarming an enemy faction hunter's trap will now flag the rogue for PvP.
• Ghostly Strike - no longer deals damage to you when you use it.
• Premeditation - Fixed a bug where the combo points gained using the ability were not properly removed after the duration expired. Also increased range and duration.
• The UI now properly shows that Preparation does not clear a Cold Blood setup.
• Set bonus for Stormshroud armor improved. It should be more compelling for rogues now.

Patch 1.5.0 (7 June 2005)

• Riposte - Fixed a bug that prevented the ability from being used when the target had no weapon or was already disarmed.

Patch 1.3.0 (22 March 2005)

• A number of areas in the world now have footlockers in them. These areas are in place for rogues to visit to increase their lockpicking skills. The contents of these footlockers are only token amounts of treasure, but they should allow for a more interesting experience while increasing lockpicking skill. The difficulty of the locks in the area correspond to the level of the zone, so if your lockpicking skill is around 100, you would go to Durnholde Keep in Hillsbrad. But if your skill is 250, you might head to Tyr's Hand in Eastern Plaguelands.
  • Hillsbrad Foothills - Durnholde Keep
