[Update #2]: Dota 2's Patch 7.31c has toned down annoying heroes like Primal Beast and Death Prophet.

[Update]: Dota 2's Spring Cleaning 2022 update has brought a whole bunch of quality-of-life improvements.

As a part of Update 7.31, Dota 2 has added the Primal Beast as a new hero, reworked Techies, as well as tweaked just about every single hero and neutral jungle creep. Unsurprisingly, due to the sheer amount of changes some rather... questionable ones have ended up slipping through the cracks.

So in order to correct some of these newfound balance problems, as well as to fix up a couple of broken skills, Valve has now unleashed Update 7.31b. Mana cost reduction now stacks diminishingly so Storm Spirit can't just zip across the map without a care in the world, Batrider is no longer a ranged version of Ursa, while Lina's recent nerfs have been somewhat counteracted with a couple of nifty buffs.

Undying's Tombstone has also had its damage reduced though it's still far stronger than it was before, while heroes like Tiny, Riki and Lycan have received some small yet rather noticeable nerfs. As for the recently reworked Techies, Blast Off! now deals self-damage based on Techies' current health (rather than max), though this buff was also accompanied by a damage and cooldown reduction.

Rather than babble on, allow me to share with you the freshly updated patch notes. That should give you a much better idea of just what has changed and what the meta impact of it all might be.

Once the next big update arrives, and it's almost certainly going to be soon given that there are still annoying issues that need to be solved, I'll make sure to let you know. Until then, have fun exploring the new meta!
