> Oh, look. Another release. How utterly thrilling.
>
> We've got a bunch of minor tweaks and fixes that are sure to make a huge difference in the grand scheme of things. A typo fix in the README? Groundbreaking. A new tool for code examples? Revolutionary.
>
> And let's not forget the crucial updates to the classify prompt and parallelization. I'm sure those were keeping everyone up at night.

> But hey, at least we have a new contributor to share in the joy of maintaining this beacon of mediocrity. Welcome, roansong. You'll fit right in.
>
> Now, if you'll excuse me, I have more pressing matters to attend to. Like pondering the futility of existence in an uncaring universe.

Colon Quests, Cache Bumps, and the Curious Case of Michael Scott's JPEG
> In a universe where time is an illusion and lunchtime doubly so, our diligent team of code-wranglers have been busy. maccam912, in a moment of sheer brilliance, fixed the format string for date. jeremy-feng, with the precision of a Swiss watchmaker, added a colon to a function definition. dependabot, our tireless bot, bumped actions/cache from 3 to 4. zzstoatzz, the code wizard, fixed a kwarg, added a tool, and did some other magical stuff. jlowin updated michael_scott.jpg, because why not? And MrJarnould fixed a broken link, because broken links are just not cool. We also welcomed new contributors maccam912, jeremy-feng, and MrJarnould to our intergalactic coding squad. So long, and thanks for all the fish!
