Clash of Clans Summer update patch notes: Army training cost changes, ‘remove all’ feature & bug fixes
Clash of Clans has released its Summer update patch notes, impacting villages, clan capital housing, and the raid medal UI.
Developer Supercell revealed the changes coming in the Summer 2022 update on June 27. Included in the patch is the removal of training costs for armies. This change was made to encourage “players to try new strategies and tactics without the worry of spending resources on something that might turn out to be a waste of time.”

Because of the drastic change to training, thedeveloper also made adjustmentsfor how Elixirs can be used, since players will no longer have to spend them on training.
The update also added some quality of life improvements to Clash of Clans, including a “remove all” function from army training so players no longer have to remove individual units from their army. Players can also use a Scenery Randomizer to improve their surroundings, and will get a notification that Capital attacks cannot be used until the full Housing Space of the Capital Army is upgraded.

The notes were posted to theirofficial blog, detailing what changes and improvements have been made to Clash of Clans.
Clash of Clans Summer update 2022: Full patch notes
ELIXIR COST CHANGES
Due to the increase in available Elixir from the removal of training costs, we’ve made some changes that primarily affect lower Town Hall levels:
“REMOVE ALL” FUNCTION FROM ARMY TRAINING
No longer will you need to remove units from your Army one at a time! Before, clearing your entire Army was a tedious process of having to manually remove every unit on an individual basis.

On your trained Army tab, you’ll see a new trashcan button added next to each category (Troops, Spells, & Siege Machines). Tapping that button will remove every unit that has been trained.
Now you can clear out your previous roster and create a whole new one faster than ever!

CLASH OF CLANS UPDATE SUPER TROOP QUICK DONATION
Is your Clanmate requesting a Super Troop reinforcement but you don’t have that Super Troop activated? In this update, you’re able to now donate any Super Troop you have access to even if you don’t have that Super Troop activated. You can only donate Super Troops you have the ability to activate.
1-Gem donations will also affect Super Troop Quick Donations and you’ll still receive credit for any Season Challenge or Clan Perk benefits!
SCENERY RANDOMIZER
The Scenery Randomizer functions just like the Hero Skin Randomizer. You can enable the Scenery Randomizer from the Town Hall. Turning on the Scenery Randomizer will allow you to select from the Sceneries you have acquired. Any time your Home Village is loaded, the Randomizer will randomly load a Scenery from the ones you’ve selected. Keep in mind that you can only select any Scenery you’ve unlocked and it will only randomize the ones you’ve selected.

ADDITIONAL GAME CHANGES AND BUG FIXES:
CLAN CAPITAL
FULL ARMY CAMP ATTACK
to ensure Clans are using their full Housing Space when attacking, players will be notified they cannot initiate an attack until they utilize the full available Housing Space for their Capital Army.
This is to prevent a common instance of players initiating their Capital attack without realizing a Capital Army Camp had finished upgrading, leading to players attacking with fewer units than they could have used.
CLAN CAPITAL PROFILE TAB
Enemy Clans during a Capital Raid Weekend can now be viewed. A button on the enemy Capital map has been added allowing you to check out the enemy Clan profile.
CLASH OF CLANS UPDATE BUILDER POTION FORGE ACTIVATION
Builder Potions can now be activated from a button on the Forge tab found in the Home Village in order to speed up crafting of Capital Gold.
CLAN CAPITAL DISTRICT CHALLENGES
Districts whose layouts were not modified during a Capital Raid Weekend will remain available for Friendly Challenges during that Raid Weekend.
CAPITAL RAID ATTACK COUNTER NOTIFICATION
Players will no longer be required to visit the Clan Capital to visually determine how many Capital attacks they have remaining.
In the Home Village, the Airship will now display the number of Capital attacks you have left to use before the Capital Raid Weekend ends.
CLASH OF CLANS UPDATE RAID MEDAL DISTRIBUTION
Raid Medals for attacks are now awarded based on the number of attacks a Raid Weekend participant did.
TRADER – RAID MEDAL UI
Items that are out of stock/sold out for purchase with Raid Medals will now display a “Sold Out” sign instead of simply being grayed out to make it visually more apparent the item in question cannot be purchased until the next inventory cycle.
And while Clan Capital may be Clash’s newest feature, we plan on adding so much more new content for you to enjoy in the future!
