If you play Dota 2, hold on to your mouse. The new Dota 2 patch notes for update 7.02 have arrived and Valve has made changes to 44(!) heroes, including Antimage and Bounty Hunter. The new update also includes numerous general changes. While many of the hero changes appear to be simple balance tweaks, a few characters did get significant modifications.

Lone Druid had both talents designed to increase damage nerfed, but Spirit Bear armor got a buff. And both Windranger and Enchantress were beefed up a bit, with Valve hoping to make them more attractive to play.

As for the overall game, you can now buy sentry wards one at a time and observer wards now simulate  fog of war before you place it. Shrines are now immune until a Tier 3 tower falls, rather than all Tier 2s needing to be destroyed.

Here is the full changelog. Be prepared, it is a long one.

General Changes

• Shrines are now vulnerable after a T3 tower dies (same as the Shrines inside the base), rather than after all T2 towers die

• Aegis expiration regen now has the same damage dispel rules as Healing Salve
• Observer Wards now have a Fog of War simulator to show you the area the ward will reveal (taking into account trees and terrain height)
• Towers no longer attack neutral team units
• The following abilities cause neutrals to temporarily not draw aggro: Meat Hook, Telekinesis and Toss
• Added more trees for TP cover around the dire towers
• Swapped the dire secondary jungle ancients and medium camp spots (and improved spawn boxes/stackability)
• The Dire ward spot to the left of the Ancients no longer gives vision over the rune area infront of Roshan
• Slightly adjusted the dire secondary jungle bounty rune further back
• Reduced spawnbox size for both Dire hard camps
• Shifted down the spawnbox for the ancient camp (formerly medium camp) in the Dire secondary jungle (so a high ground ward does not block the camp) 
• Fixed a rare case where Dire ancients could be stuck between trees when spawning
