TL;DR
🚀 Up to 2 times speedup with Incremental compilation.
▶️ Up to 30% size improvements
🐞 Better variable view when debugging inside browsers
🚨 Breaking change: browser APIs and helpers are moved to a dedicated kotlinx-browser library
⚡️ Better handling for exceptions on the border with JS.
🛠️ Built-in helpers to interact with JS Arrays

Not gunna lie, this is probably the most interesting change lol, shame already converted my tests to not use backticks 😢 (https://kotlinlang.org/docs/whatsnew-eap.html#support-for-non-identifier-characters-in-kotlin-js-properties)

Also we can't use 2.0.21/2.1.x until two breaking bugs are fixed, was hoping they would get caught in Beta 2 but alas not 😞

[chrisjenx]

Looks like this one didn't make it into beta2 ? https://youtrack.jetbrains.com/issue/CMP-6842/FAKEOVERRIDE-declarations-are-not-preserved-in-metadata-and-should-not-be-marked-with-annotations

[chrisjenx]

One breaks iOS builds the other JVM builds, literally both mobile clients lol

[bashor]

Fix for CMP-6842 should shipped with 2.1.0-RC

[bashor]

About another one 🤷‍♂️ it’s better to ask in the issue

[chrisjenx]

Yeah I'll nag, supprised noone else has noticed TBH, it's not that wierd of an edge case

[chrisjenx]

Looks like they got it fixed, hopefully merged into the next release, excited to try all the new 2.1 goodies
