There are things that’s hard to do right in Kotlin Multiplatform. Which of them are you missing?

[Kotlin by JetBrains @kotlin]

🚀 One of the biggest announcements at #KotlinConf26 was the Kotlin Toolchain.
It’s a unified entry point for:
⚡ Creating apps
⚡ Building and testing
⚡ Formatting
⚡ Doc generation
⚡ AI agent integrations
Available today for JVM and KMP projects.

If anyone is still interested in sweet-spi, a.k.a. my take on SPI in KMP, feel free to check the project status update at the link below.
TL;DR: KSP will be replaced by Kotlin Compiler Plugin... When I have more time...

Documentation tooling in Kotlin has been an afterthought for too long.
New KEEP proposes to change that
Kotlin Documentation Model - a stable, machine-readable representation of your module's KDoc and API surface, integrated into the Kotlin Build Tools!

Thanks, everyone, for the support and for nine more stars! Now it's just 78 more stars! Never enough, hah?

[Oleg Yukhnevich @why_oleg]

One more star? Anyone?

[Oleg Yukhnevich @why_oleg]

Thanks to all fourteen "one more star"! It was really unexpected!

So, for the next milestone, 87 more stars, anyone?

@vergauwen_simon True, supporting every use case in a logging library is almost impossible, there are a lot of sacrifices along the way. So, yes, maybe, we don’t need standard logging library at all? :)

[Oleg Yukhnevich @why_oleg]

Why does everyone wants to create a logging library?
I mean, I’ve seen more than 50 Kotlin libraries, most of them doing roughly the same…
There is even four libraries with ~+1000 stars!
And still, every month in a while one more is created
And still, there is no default choice

[Oleg Yukhnevich @why_oleg]

@vergauwen_simon Yeah, yeah.
Still, why not to contribute instead of creating new one?
That’s what I can’t understand…

[Oleg Yukhnevich @why_oleg]

@sur3shg I’m curious, why do you think that logging should be first party?
Not every popular/modern language/ecosystem has first party logging API, or, even could have one, but no one will use it (hello Java)

[Oleg Yukhnevich @why_oleg]

See for yourself: https://t.co/wqP8SM345R
Should we (as a community) do something about it?
Of course, I’m not against creating new libraries, but do you think that all this enthusiasm could be redirected to other, less developed categories?

[Oleg Yukhnevich @why_oleg]

@Silverhand83 At this moment only GitHub Sponsors

[Oleg Yukhnevich @why_oleg]

[Oleg Yukhnevich @why_oleg]

Thanks to everyone who uses and contributes to the project - it truly means a lot ❤️
If you or your company rely on the library, consider supporting its development. This helps keep it maintained and evolving.

[Oleg Yukhnevich @why_oleg]

But the most exciting part isn’t the release itself, it’s the people who use and contribute to the library!
Recently, I collected statistics on algorithm usage and was impressed by the number of projects and the variety of use cases!
