Alpha 3 Game Changes, located here: http://www.harrisgamedesign.com/phpBB3/viewtopic.php?f=40&t=6149 appear to have been made official (as they are integrated into the official ruleset.)
Soviet/Japanese Non Aggression Pact: Due to their mutual border conflct with Japan in 1939, the Soviet Union and Mongolia have a special relationship. If the Japanese attack any Soviet territory that is adjacent to any Mongolian territory, all Mongolian territories (Olgiy, Dzavhan, Tsagaan-Olom, Central Mongolia, Ulaanbaatar, and Buyant-Uhaa) that are still neutral are placed under the control of the Soviet Union at the end of the Japanese Combat Move phase, in the same manner as though the Soviet Union had moved land units into a friendly neutral territory. These territories have Soviet control markers placed on them, and their standing army units are placed on the board and are controlled by the Soviet Union player from then on. This occurs regardless of the state of relations between the Soviet Union and Japan at the time of the attack, with one exception: If the Soviet Union attacks any Japanese-controlled territory bordering these Mongolian territories while Mongolia is still neutral, Mongolia will remain neutral and not ally itself with the Soviet Union. In addition, the Mongolian territories will never become pro-Axis unless one or more of them is attacked by the Soviet Union.
Soviet Union
When the Soviet Union Is at War in Europe:
• 3 IPCs for each original Axis territory the Soviet Union controls. Theme: Propaganda value and spread of Communism.
(Note: 3 IPC for Korea now too!)

• 5 IPCs if Axis powers control all ofthe following territories: Guam, Midway, Wake Island, Gilbert Islands, and Solomon Islands. Theme: Strategic outer defense perimeter.
• 5 IPCs per territory if an Axis power controls India (Calcutta), New South Wales (Sydney), Hawaiian Islands (Honolulu) and/or Western United States (San Francisco). Theme: Major Allied power centers.
• 5 IPCs if Axis powers control all of the following territories: Sumatra, Java, Borneo, and Celebes. Theme: Strategic resource centers.
• 5 IPCs if the United Kingdom controls both Kwangtung and Malaya. Theme: Maintenance of the empire considered vital national objective.
The United States:
• 5 IPCs (one time payment) if there is at least three US units, at the same time, in Normandy/Bordeaux or Holland/ Belgium following an amphibious assault. Theme: Great Alliance collaboration
England gains 1 Strategic Bomber on England in the initial setup.
France loses 1 Armor in W. France (Normandy) and replaces it with 1 Artillery.
New SBR rules, to include proposed changes to Air Defense, are integrated into the official ruleset.
These changes are listed above.
Same for proposed convoy raid changes, those are also included in the official ruleset. Those changes are also listed above.
Technology:
Rockets: Your air bases can now launch rockets. During the Strategic and Tactical Bombing Raid step of your Conduct Combat phase each turn, each of your operative air bases can make a single rocket attack against an enemy industrial complex, air base, or naval base within 4 spaces of it. This attack does one die roll of damage to that facility. Rockets may not be fired over neutral territories.
(Note: Rockets previously had a range of 3 spaces, now they have 4 spaces to be fired from.)
