~Does updating to Kotlin 1 5 cause a binary incompatibility

Question

~Does updating to Kotlin 1 5 cause a binary incompatibility with libraries that use `kotlinx datetime` and are compiled with 1 4 ~ I guess `kotlinx datetime` isn t actually compatible with Kotlin 1 5 scream Must be the change of `Duration` from `Double` to `Long` gt java lang NoSuchMethodError kotlinx datetime Instant kotlinx datetime Instant plus LRDsOJo long

gt Must be the change of Duration from Double to Long First that but also the change of mangling for methods with inline class parameters in 1 4 30 1 5

Marc Knaup · Answer

Do you have any ETA on that

Paul Woitaschek · Answer

Ah ouch We re stuck with 1 5 0 M2 because we can t use 1 4 as the commonizer runs on every single gradle module there which makes bitrise timeout at 90 minutes

ilya.gorbunov · Answer

We ll release a compatible version of kotlinx datetime some time before Kotlin 1 5 release We re working at the moment on building it and you ll be able to fetch artifacts from our build server as soon as they are ready I ll provide a link to it that could be used as a maven repository
