Due to Update changelog being way too big, Steam cannot handle it. Check out either our forums page[forums.terraria.org] or on our Discord Server[discord.gg]'s Changelog channel!
Heres a tldr from Forums:

2.0 Update
New Mechanics: Ability Haste, Pet Swapping Cooldown, Pet effects are now active by the Player's Pet slot
Heavily improved Lifesteal mechanic, improved all item related Pets, new Weighted tables, Slow mechanic is reworked to work correctly, reworked uninteresting and old perks, re-wrote almost entire code to be more efficient and superior to old code, made the Mod more accessible to outside (is now more modifyable and way more friendly with new Methods+explanations, old code barely was), made whole code a million times more readable, smoothed all effects where possible, a whole bunch of balance changes, a lot of major and minor bug fixes and more that isn't crossing my mind right now.

Buffed Shadow Mimic to now grant +6 tile range for picking up coins.
Nerfed Harpy Pet to now make wings unusable till cooldown is refreshed, meaning its impossible to Glide with Harpy Pet now, though, still grants fall damage immunity.

Version 1.2.3.1 has been published to Stable (v2023.6) learn more @ https://discord.gg/adeRNh9Mw

Patch 1.2.3.1 - September 4, 2023
Fixed an issue with all Pets that works with Item pickups (eg. Junimo, Mining Pets, Harvesting pets), where if Player is in Multiplayer, it would not check properly if item had been picked up before, allowing to throw and re-pick up item to proc benefit the Pet in use provides.
Now pets that works with item pickups checks if the item's maximum stack is not 1 for their effect to work on said item. (Eg now Squashling can't increase Magical Pumpkin Seed's stack or Junimo cannot give 3x Harv lvl copper from the Magical Pumpkin Seed or any item with same property)

Version 1.2.3 has been published to Stable (v2023.6) learn more @ https://discord.gg/adeRNh9Mw

Config Update, Patch 1.2.3 - August 25, 2023
Added Config options for disabling Junimo Notifications, making Pet Tooltips toggleable with down button and disabling custom hurt sound effects.
Added Bunny Pet.
Removed Hay from Junimo's Harvesting crops table.
Added a check to Angler Quests for Junimo Fishing Exp if another Angler Quest has been claimed that day to prevent exploits with other mods. This resets every day and is saved on the Player, meaning this prevents Player from getting a quest in one world and going to another to re-claim it unless they complete a day.
Now Junimo's tooltip says: Max Level! next to Exp needed for next level if maximum level has been reached.
Fixed while Zephyr Fish and Fishron are in use and full Angler Armor is worn, tooltip addition to Angler Armor appearing for all items.
Fixed Tiki Totem displaying chat message.
Fixed Spring Eye jump not playing sound effect.
