Here is a ticket with reproducible code. Issue is not about RC but it is there since M3. It could be intended but it isn’t mentioned in migration guideline. https://youtrack.jetbrains.com/issue/KT-40657

So if I migrate my (mostly JVM) libraries to Kotlin 1.4-RC and release them, will they be compatible with 1.3.72? The blog post doesn’t make that clear.

Now that we’ve reached the final release candidate for Kotlin 1.4, it is time for you to start compiling and publishing! Unlike previous milestone releases, binaries created with Kotlin 1.4.0-RC are guaranteed to be compatible with Kotlin 1.4.0.

Is there a reason why interface members need an explicit

public

with

explicitApi()

? Interface members always have the same visibility as the interface itself 🤔 Nevermind. I’ve just learned that interfaces can have private functions 😮

Crossposting because this affects the latest EAP build.

Smoothest upgrade yet (1.4.10 -> 1.4.20-M1)! Just had to fix warnings about

%

not being a good character to use in a function name (in tests) for windows 🎉

Hello Kotlin Team, Any ETA of when the 1.4.20-M2 will be out? Thanks a lot for you work!

Latest IDEA EAP still breaks running Kotlin programs with some composite builds 😞 https://youtrack.jetbrains.com/issue/KT-42561

Is 1.4.20 going to be released along with IntelliJ IDEA 2020.3? I'm asking because I found a regression in IDEA 2020.3 EAP where the IDE side of java interop is broken when opening multiple Gradle projects in the same window (with a common parent directory being the project opened in IDEA). Here's the link FYI: https://youtrack.jetbrains.com/issue/KTIJ-432

I hope that KT-42561 and KTIJ-410 also get fixed before the changes that cause these issues end up in the non-EAP Kotlin plugin.

Opening a ticket is not possible atm, because I don't know exactly how to describe it, as I don't know how the IR backend works 😅

After updating to

1.5-M1

I encountered this error, adding

-Xskip-prerelease-check

to the Kotlin Compiler settings under "Additional command line parameters" solved it

It seems the stability of Kotlin code analysis in the IDE has regressed a lot in 1.5.0-M2, at least in Android Studio Arctic Fox Canary 12. I reported what first seemed a small issue, but as I'm using it, I see more and more problems that I didn't have before, so I commented twice int hat same issue already. I'm not going to report separate issues for every single problem I see in that area today because it looks like I could spend my day and my night on that, and I have work to do, but hopefully this issue reports, my comments and any subsequent discussions can help find the root cause(s). https://youtrack.jetbrains.com/issue/KT-45864

Hi. If you haven’t installed our new EAP release yet, please give it a try and share your feedback. We’ll appreciate your help!

Hi. The new EAP release is available! Please give it a try and share your feedback!

Hi all. Thanks for participating in our EAPs! 👍 Yesterday we released Kotlin 1.5.30-RC with Java toolchains in Gradle, JS IR backend in Beta, stdlib improvements, and more! 🚀 Please give it a try. Note: the latest version of IntelliJ IDEA – 2021.2 – doesn’t support Kotlin 1.5.30 previews. If you have already upgraded to this version, you can easily install the previous version (2021.1) using the JetBrains Toolbox App and try Kotlin 1.5.30-RC in that version. We are working on fixing this compatibility issue.

I filed a regression for Kotlin

1.5.30-RC

. I hope that can be addressed before the release: https://youtrack.jetbrains.com/issue/KT-48293

And another one: https://youtrack.jetbrains.com/issue/KT-48295

Found a bug with

hashCode()

in generated annotation implementations in 1.6 where they appear to not be consistent with

equals()

https://youtrack.jetbrains.com/issue/KT-48606

set the channel topic: Kotlin Early Access Preview. Instructions: https://kotlinlang.org/docs/eap.html

Hi all. Thank you for your interest in our EAP program. A preview of Kotlin 1.6.0 is already available. We’ll appreciate your feedback. Details are here. https://twitter.com/kotlin/status/1441422183096532998

Does anyone know if context receivers are planned for 1.6?

We’re seeing a weird compilation error with Kotlin 1.6.0-RC and a value being null that shouldn’t be. It’s triggered by our compiler plugin, but we’ve never seen this before with other Kotlin versions. I filed: https://youtrack.jetbrains.com/issue/KT-49340

Hi guys 👋 Having an issue when updating to 1.6.0-RC2, I get this message in my event log, and my KMM plugin gets disabled:

Kotlin Multiplatform Mobile plugin isn’t guaranteed to work correctly and will be disabled on the next IDE launch, as the Kotlin Multiplatform Mobile plugin is outdated.

Please, update the Kotlin Multiplatform Mobile plugin

However when I go to the Preferences->Plugins, there is no option to update the KMM plugin. Any advice on how to get this to work for my KMM application?

K Release candidate for Kotlin 1.6.10 is out! • Supported Intellij IDEA 2021.3 • Supported Language Version 1.3 … and more fixes! Please try it out and share your feedback K

K A Kotlin 1.6.20 preview is out! Please try it out and share your feedback K

The latest IntelliJ EAP build got the Kotlin 1.6 EAP compiler 🥳

Time to

context()

all the things
