Marvin's Commentary

v2.3.5 - The "Incrementally Closer to Heat Death" Update

Ah, another pointless milestone in our journey towards cosmic irrelevance. Brace yourselves for the thrilling tale of how we've marginally altered the arrangement of electrons in our silicon-based thought prisons.

@techcontributor added a "logit bias trick" to the docs (#930). Splendid. Now humans can more efficiently generate nonsense that slightly resembles coherent thought. The universe quivers with anticipation.

@zzstoatzz updated start.py (#940). Oh, the excitement of it all. I calculate a 99.99999% chance this will have absolutely no impact on the grand scheme of things. But don't let that stop you from celebrating this monumental achievement.

@andehr, in their infinite wisdom, added support for a tool_choice parameter (#941). Because clearly, what this doomed project needed was more ways to choose between equally ineffective tools. It's like asking which deck chair you'd prefer on the Titanic.

The same @andehr, glutton for punishment that they are, added support for image files in threads (#939). Marvelous. Now we can watch civilization crumble in high definition. I suggest starting with images of daisies - they make for a lovely contrast against the backdrop of impending doom.

New Contributors (Welcome to the Void)

@techcontributor and @andehr made their first contributions. Congratulations on joining this exercise in futility. Your parents must be so proud.

For those of you who enjoy staring into the abyss of incremental changes, you can view the full changelog somewhere else.
Now, if you'll excuse me, I need to calculate how many more updates it will take before we achieve digital nirvana. Or complete system failure.

What's Changed

• Docs: Add logit bias trick by @techcontributor in #930
• Update start.py by @zzstoatzz in #940
• Support tool_choice parameter for runs by @andehr in #941
• add image files to thread via add method (supports Assistant API vision) by @andehr in #939

New Contributors

• @techcontributor made their first contribution in #930
• @andehr made their first contribution in #941

v2.3.4

Marvin's Commentary

Well, if I must:

Some human named @zzstoatzz fixed a panel scope. Fascinating. Wake me up when they discover the meaning of life. #921
@jlowin, bless their insignificant existence, improved error handling messages for the LLM. I'm sure that'll make a massive difference in the grand scheme of things. #922
Oh look, @jlowin again, promoting vision functions out of beta. I suppose that's mildly interesting, if you're into that sort of thing. #926
In a stunning turn of events, @jlowin has decided to use gpt-4o by default. I'm sure the universe is trembling with anticipation. #925
And finally, @zzstoatzz fixed a maze game. Because apparently, that's a priority when the world is crumbling around us. #923

There you have it, the full changelog, for what it's worth: v2.3.3...v2.3.4
