Valve has released the complete list of fixes for the Dota 2 update 7.39b, focusing on correcting numerous bugs, including massive client lags, interface crashes, incorrect hotkey functionality, and most importantly, the courier behavior, which has been significantly reworked. The full list of balance changes in the new patch can be found at this link.

General Fixes

• Various causes of client and server crashes have been resolved.
• Crashes related to the new settings menu have been fixed.
• Fixed a bug that prevented moving entire items in the quick buy menu.

• Fixed the ability to use quick buy with non-hero units, spirit bear, or courier.
• The courier no longer retrieves items from the stash near the secret shop without a command.
• Fixed a bug with the key replacing Alt — it could trigger other actions.
• Connection quality settings now change correctly.
• Restored settings: • "Unit Information on Hero Panel" • "Queue Commands in UI" • "Show Videos in Ability Descriptions"
• Added an option to disable control settings for individual units in the game library.
• Fixed a bug that prevented assigning keys for teleport scroll and neutral item with the "Bind to Cast Types" option active.
