TL;DR
:rocket: Up to 2 times speedup with Incremental compilation.
:arrow_forward: Up to 30% size improvements
:ladybug: Better variable view when debugging inside browsers
:rotating_light: Breaking change: browser APIs and helpers are moved to a dedicated kotlinx-browser library
:zap:️ Better handling for exceptions on the border with JS.
:hammer_and_wrench: 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 :cry:  (<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 :disappointed:

<@U0KHPTQHE> which issues?

<https://youtrack.jetbrains.com/issue/KT-71649/K2-Put-operator-on-mutableMapT-V-causes-crashes-on-null-key>

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>

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

Fix for <https://youtrack.jetbrains.com/issue/CMP-6842|CMP-6842> should shipped with 2.1.0-RC

About another one :man-shrugging: it’s better to ask in the issue

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

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