Since releasing The Summer Client Update we've addressed a number of issues:

• Fixed a bug that would appear to allow you to commend/dislike the same player multiple times in postgame
• Fixed an issue that would sometimes cause behavior score or communication score to get set to 0 incorrectly (the affected accounts have had their appropriate scores restored)
• Re-added the ability to rotate your hero with mousewheel in the Armory and pregame
• Re-added the ability to demo custom terrains
• In games where the majority of connected players have a behavior score too low to allow them to pause the game, those players will now be able to unpause if the game has been paused for at least 5s
• Added persona selector to pregame loadout
• Added slot headings to pregame loadout
• Re-introduced Hero Relics into the shard shop
• Disabled rebundling for items with unlocked styles, or which unpack with dynamic gems
• Owned world items can now be demoed through the item details popup
• Improved the display of chat wheels in the new Armory
• Commending a player no longer prints a chat message every time (to prevent post-game commend sprees from pushing all actual chat offscreen)
• Added a new, distinct sound for disliking a player
• Fixed grouping by item type in the All Items tab in the Armory
• Fixed announcer packs not loading properly when entering pregame
• Fixed places in the new Armory where fonts would sometimes display at an incorrect size
• Fixed an issue that would sometimes cause dead units to not stay dead (Undying, Spirit Bear, Wraith King)

• Fixed an issue that would cause the game to change monitors when running in fullscreen on multi-monitor displays
• Fixed Dark Seer's "More Than Mental Mass" taunt not playing sounds

• Fixed a crash on MacOS versions older than 10.15

• Fixed display of owned Kill Streak Effect in the Shard Shop
• Fixed incorrect items sometimes appearing under the Tools section in the Shard Shop
• Fixed some cosmetic particle effects not showing properly when previewing items in the Loadout or in the Armory (Void Spirit weapon particles, for example)

• Fixed Dota Plus quest to commend players not correctly counting all commends
• Fixed a server crash when players were spectating under certain conditions
• Fixed a rare courier-related server crash in Turbo
