10/09/2025, 10:27 PMunless you do some specific work otherwise, it means your library metadata will be 2.2, and you will have a dependency on kotlin-stdlib:2.2.20, which means any consumers below kotlin 2.1 will break

10/14/2025, 3:33 PMIMO depends on your consumers relativity to you a ton too. I'd probably stay on older versions for stuff that is consumed by 3rd parties, but for internal libraries I upgrade aggressively and just tell coworkers to stop being so lazy about updating given they have to be 2 versions or more behind for it to become a real problem. at that point they can just stay on an older library version until they are ready to update.
