Don't ignore this tip! We've switched to using the optimized proguard file & shrinking resources in our latest release and have seen a massive drop in all performance related metrics, with slow app launch metrics dropping >30%. All from a 5 minute code change!
Run this and let me know the output:
`grep "dontoptimize" app/build/outputs/mapping/release/configuration.txt`
In case it's not empty, you definitely should watch this youtu.be/QqO2jZ-NZko?...

We've been using Navigation 3 since early alphas and it's perfect for us.
We looked for a navigation solution for a while until nav3 came along - nothing quite fit the bill. Nav3 is the perfect combination of being very flexible and solving the hard problems.
Congrats on hitting stable!

Jetpack Navigation 3 is stable! 🎉🎉🎉
Leaning into Jetpack Compose and the idea of combining smaller building blocks together really helped make Nav3 a much more flexible library that made it a joy to work on and hopefully for you to use as well!

Been working a little on iOS recently and while Android tooling has its issues it is just miles ahead of iOS when it comes to the IDE & build tooling

(bars represent actual counts, so both years are on the same scale)
Some quick analysis in follow-ups
