Pebble going fully open source is a big win for hardware preservation. ⌚️🔓 But for mobile devs, the real story is in the repo.
The new app is a pure KMP + Compose Multiplatform rewrite.
230k lines (Legacy Java/ObjC) ➡️ 37k lines (Kotlin)
Shipped in 6 months with just 2 devs 🔥

Well done to Slack for breaking the app in new in exciting ways. This time, clicking on Windows notifications doesn't open the app anymore.
Of course this is on top of the *years* old bug that clicking on a notification unmaximizes the windows on a secondary monitor.

Context parameters are almost here, let's try migrating a real codebase to them and see what happens!
If you've heard of them but haven't had the time to dive yet, follow me to discover what they can and can't do right now, ahead of their final stabilization.
