This is where all of the patch notes before 4.0 are.

Patch Notes [3.1]:

Hotfix [3.1.1]:

• Changed the way I track some statuses, and that means no "wait" commands, which means...
  • NO ERROR MESSAGES FOR MUSICALITY, ELASTIC TENDONS, AND MUCUS DERMIS (GOD DAMN IT PLEASE)

Fixes and Changes:

• You can now select "Nothing" as a quest choice if you don't want to pick a quest.
• Musicality should no longer have error messages.
• Elastic Tendons should no longer have error messages.
• Mucus Dermis should no longer have error messages.
• Diamond Nose is no longer called "NDiamond Nose" in the quest selection menu.

Hotfix [24/12/2018]:

• Musicality stacks 50% faster.
• Elastic Tendons charges twice as fast and can grow 50% larger.
• Protomutant's Blessing success rate now 67% (from 50%).

• Hot Pockets' pellets' damage scales faster and to a higher max damage.
• Mucus Dermis slows time by 4x (from 3x).
• All quests actually work now!

Patch Notes [2.5]:

Hotfix [2.5.5]:

• Mucus Dermis and Elastic Tendons should no longer spit out errors.
• Only the latest hotfix will be available for download since previous hotfixes have broken functionality.

Hotfix [2.5.4]:

• Quests should actually work now (this time I'm actually pretty certain).

Hotfix [2.5.3]:

• Protomutant's Blessing now checks for levels above ultra too, in case you have a mod that lets you skip level ultra completely.

Hotfix [2.5.2]:

• Fixed an error involving Rocket Fists and rockets.

Hotfix [2.5.1]:

• Fixed issues involving quests actually working (hopefully).
• Fixed an error spat out when dying with Mucus Dermis or Elastic Tendons (hopefully).

Fixes and Changes:

• Hyper Hunter quest requirement reduced from 25 to 20.
• Hot Pockets chance to fire increased from 25% to 33%.
• Gunpowder Piercings chance to proc increased from 25% to 33%.
• All previous versions of Vineskills since 2.0 are now available for download on this page.

New Mutations:

• Rocket Fists— Explosives will carry a damaging punch with them, dealing damage so small enemies won't detonate the explosive.

Additional Notes:

Rocket Fists: Rocket Fists was made as a mutation to combat the age-old problem of your nukes blowing up in your face because a maggot walked up to it, so hopefully it actually works for that situation and offers a nice way of making explosives more viable.

Patch Notes [2.4]:

Fixes and Changes:

• I finally touched this mod after like a year, neat.
• Elastic Tendons should actually work properly after getting revived in co-op. If it doesn't, ping me on discord or whatever and maybe I'll get to fixing it in the next year.
• Perfect Storm's kill requirement decreased from 30 to 5. I'm stupid and didn't realize just how rare these things are. You should now be able to complete the quest in loop 1 with CoB and decent RNG or loop 2 without CoB and average RNG.

New Mutations:

• Mucus Dermis— Briefly slows down time when you get hit.

Additional Notes:

Mucus Dermis: I liked the concept of a "bullet time" defensive option so I spent almost 2 hours just trying to make this thing work properly (because damn did it not want to work). Could potentially need a buff in power or effects if it ends up too similar to Elastic Tendons.

Patch Notes [2.3]:

Fixes and Changes:

• Nomad's Sole, Hyper Hunter and Perfect Storm all have new buttons/icons thanks to Peas (praise be).
• Hyper Hunter's bonus IDPD damage increased from 33% to 50% and has a chance to give non-elite IDPD a heart attack (probably from eating too many donuts on the job), killing them instantly on spawn.
• All quests now display their progress upon hovering over them in the HUD.

Patch Notes [2.2]:

Hotfix [2.2.1]:

• Changed a tad bit of code so bad things don't happen in the future.

Fixes and Changes:

• Musicality no longer spews out numbers upon picking it (whoops, I had left trace(Musicality) in there for debugging!).
• Elastic Tendons no longer makes your game lag to hell (thanks Saniblues for pointing out the fact that I was creating a CustomDraw every step).

Patch Notes [2.1]:

Fixes and Changes:

• Error messages showing after exiting while having Elastic Tendons should be fixed (hopefully).
•  Hot Pockets received a large buff. (see below for additional notes).
• Musicality now works properly with Steroids (have fun with 'roids bullet builds!).

Additional Notes:

Hot Pockets Changes: Hot Pockets was a pretty odd mutation due to it's RNG. Gamma Guts isn't often picked, so Hot Pockets was meant as a similar, more interesting mutation. However, it was inconsistent and didn't deal enough damage. The changes in particular are as follows: The rate at which the pellets are fired out has been doubled, and the damage of the pellets scales with level (at level one, 1 damage pellets, at level 5, 3-2 damage pellets, and 6-4 damage pellets at level 10). Hopefully, the mutation is put in a better, more usable state with these changes.

Patch Notes [2.0]:

Fixes and Changes:

• Mucus Dermis removed (kinda broken and also replaced in usage by Elastic Tendons).
• Seeking Bliss removed (Who ever picked this useless mutation anyway?).
• Protomutant's blessing has a new icon courtesy of "Peas".
• Pincushion Lungs now affects seekers fully.

New Mutations:

• Gunpowder Piercings— Bullets have a chance to explode on death.
• Elastic Tendons— You slowly charge a blast that repels enemy projectiles upon getting hit.
• Hot Pockets— Fire pellets will constantly occasionally spew out of you (they are affected by mutations that affect flame pellets too).
• Musicality— Firing the same weapon within a moderate frame of time after reloading it reduces it's cooldown.
