This thread brought to you by a tremendous dickhead!

• Hoenn remakes: Pokémon Omega Ruby and Pokémon Alpha Sapphire have been announced for November release.
  
• Distribution: Celebi, for users of Pokémon Bank. This distribution runs until the end of September. Note that if you didn't get your Celebi while the free trial period for Bank was still on offer, then you will have to pay for a subscription to Pokémon Bank in order to get it. Celebi will be given to you when you run Pokémon Bank after having received your Poké Miles or Battle Points in-game using the Pokémon Link icon on the main menu. Celebi will be placed in your PC when you use the Pokémon Link function again.
  
• Tournament: The current Goon Tournament is a Singles tournament. Visit the Goonleague thread to find out more.
  
• The most up-to-date version of Pokémon X and Pokémon Y is currently version 1.2 (update released in December of 2013). If you are running an earlier version, you should visit the 3DS eShop, where you can download an update to the latest version for free. If you are not sure what version you are running, it is displayed in the bottom-right corner of the 3DS's touchscreen when you are on the main menu (the menu that appears when you press A at the title screen, with "Continue" and "Mystery Gift" as options).
  

• Pokémon-Amie - You can now pet your Pokémon and feed them candies using the 3DS's touchscreen. Playing with your Pokémon makes them friendlier and may make them perform better in battle (only in normal in-game battles; not in link battles or in the Battle Maison).
  
• Fashions - You can now dress up your avatar in different outfits! You get access to more articles of clothing as you progress in the single-player quest. Pokémon Centres now have changing rooms where you can change into different outfits. You can save up to 6 outfits as your favourites. You also get to choose your skin and hair colour (well, you get to choose between three shades, anyway).
  
• Super Training - If you know and care what EVs are: These are minigames that allow you to build up and/or reset your Pokémon's EVs by training with them. If you don't know or care about EVs: These are some fun minigames you can play with your Pokémon.
  
• New online connectivity features - Friend Safari is a neat new feature where you can go to a little garden and catch Pokémon based on the Friend Codes of people you have added as friends. Each Friend Code is used by the game to determine 3 Pokémon which will appear in that person's Friend Safari. These Pokémon sometimes include the starter Pokémon from generations 1 and 6. Pokémon encountered will sometimes have their Hidden Abilities. (Until the person has beaten the game and accessed Friend Safari themselves, and then gone online at the same time as you, you'll only be able to find 2 of their 3 Pokémon, and Pokémon in their Friend Safari will never have their Hidden Abilities.)
  
• Battles are in 3D - Well, the whole game has gone 3D in terms of the art direction. No more sprites, except in some menu screens. Only the battle scenes use the 3DS's 3D imaging functionality.
  

• Longer names - Your trainer name, and your Pokémon's nicknames, can now be up to 12 characters in length.
  
• Berry farming is back - We can now farm berries on the 3DS again! You get a little garden where you can grow berries. To ensure that you get a good yield, be sure to water them occasionally and protect them from wild Bug-type Pokémon who want to eat them. (Berry trees are also found in the wild, but they just drop specific berries occasionally, and can't be replaced.)
  
• Experience changes - Experience has been simplified. Instead of the experience points from fainting an opponent being split amongst the Pokémon that took part, each Pokémon just gets the full amount of Exp. However, the level scaling from Generation 5 is gone (a level 5 Pokémon in your party and a level 50 Pokémon in your party once again get the same amount of experience when the opponent faints). The Exp. Share is now a key item that can be turned on or off. When it is on, even those Pokémon that did not battle get experience, but only half as much as the Pokémon that did battle. Finally, your Pokémon gain experience when you capture a wild Pokémon, just as though you had fainted it.
  
• Breeding changes - Hidden Abilities can now be passed down from either parent, even when breeding with Ditto. (They are still more likely to be passed down when the mother has her Hidden Ability, however.) Also, both parents can now contribute Egg Moves. An existing item, Destiny Knot, now has a function in breeding; when held by either parent, it increases the number of IVs passed down from 3 to 5. (The IVs do not necessarily come from the parent holding the Destiny Knot. If the other parent holds a power item, then the stat corresponding to the held power item will be one of the 5 IVs passed down; at least one IV is always randomly determined.)
  
• The Poké Radar is back - The Poké Radar was a neat device available in the Sinnoh games that allowed you to "chain" wild Pokémon encounters and eventually find shiny Pokémon. It's available once again in Kalos. It's been made less effective though, because finding a shiny Pokémon will end your chain. It's also a bit harder to use than it was in Sinnoh, because the patches of long grass are generally smaller.
  

• Mega evolutions - A number of Pokémon from previous generations have gained special battle-only forms known as "mega evolutions". These forms generally have better stats, a better ability, and/or different typing. There are some catches: to "mega evolve", a Pokémon has to be holding a special item (specific to its species), and only one Pokémon on your team may mega evolve in a given battle. (Some Pokémon even have two different mega evolutions, triggered by different items.) Mega evolution occurs at the beginning of a turn when you choose to trigger it, and the Pokémon still gets to act that turn. If a mega-evolved Pokémon switches out, it will still be mega-evolved when it switches back in, but it will revert to normal when the battle ends. Mega evolution cannot be undone, save by ending the battle.
  
• The Fairy type - The type chart expands from 17 to 18 types with the addition of Fairy. Some new Pokémon are Fairy-type, but a bunch of Pokémon from previous generations have been made Fairy-type as well; the same is true for moves. Fairy-type moves do super-effective damage to Dark-, Dragon- and Fighting-types, and not-very-effective damage to Fire-, Poison- and Steel-types. Fairy-types take super-effective damage from Poison- and Steel-type moves, and not-very-effective damage from Bug-, Dark- and Fighting-type moves. They are immune to Dragon-type moves.
  
• Tweaks to the type chart - Steel has lost its resistances to Dark- and Ghost-type moves.
  
• Typing immunities - Some Pokémon types can now ignore certain moves and game mechanics. Electric-types cannot be paralysed. Grass-types are unaffected by attacks that involve the use of powders or spores. Ghost-types are unaffected by "trapping" moves (Mean Look, Fire Spin, etc.) and abilities (Arena Trap, Shadow Tag). As before, Poison- and Steel-types cannot be poisoned, and Fire-types cannot be burned.
  
• Changes to critical hits - Critical hits now only boost damage by 50%, rather than doubling it as before. They still ignore defending stat buffs on the defender and attacking stat debuffs on the attacker. Some of the mechanisms that allow you to increase the likelihood of critical hits (for example Focus Energy) have been buffed to increase it more than they did previously.
  
• Changes to weather - Weather conditions induced by Pokémon abilities now expire after 5 turns, as with the moves that induce weather. This can be extended to 8 turns using the appropriate hold items.
  
• Changes to moves - Defog is good now, because it affects both sides of the battlefield. Hidden Power is now always 60 base power, and only varies in type. It still cannot be Normal-type, and now it cannot be Fairy-type either. Will-O-Wisp has had its accuracy increased to 85%. The elemental Pledge moves (Fire Pledge, Grass Pledge and Water Pledge) have had their base power increased substantially, from 50 to 80, and so they might be usable in Doubles and Triples now.
  
• Tweaks to moves' base power - Several high-power moves (Blizzard, Hurricane, Hydro Pump, Thunder, and others) have been nerfed slightly, having had their base power cut by 10. Some other moves that have historically been staples of competitive battling (Flamethrower, Ice Beam, Surf, Thunderbolt) have been reduced from 95 to 90. Meanwhile, Energy Ball has been adjusted upwards from 80 to 90, to meet these moves.
  
• New Pokémon, moves, abilities, and hold items - As with any new generation, a bunch of new stuff is available to try out. Interesting new Pokémon from a strategic point of view include Aegislash (which swaps between a heavily defensive form and an attacking form depending on the moves you use) and Klefki (a new Prankster 'mon). Some older Pokémon that previously had only one regular ability now have two. Interesting new hold items include the Assault Vest and the Weakness Policy.
  

• Can the boy player character wear girls' clothes? - No. Different articles of clothing are available to the boy and girl player characters.
  
• Has Stealth Rock been changed? - No (although there are more answers to it now, since Defog has been buffed so as to actually be useful).
  
• Can you auto-level to level 100 in Wi-Fi battles? - No, but you can auto-level to level 50. Even for 6v6 battles! (This was unfortunately missing in Generation 5.)
  
• Is movement still on a grid? - When walking or runnng, movement is still on a grid, although now you can move diagonally. When rollerblading, cycling or surfing, movement is not constrained to the grid. When you go back to walking, you step onto the nearest grid square.
  
• Can I use the Poké Radar in a Friend Safari? - No.
