I think you may want to disable `MapperFeature.SORT_CREATOR_PROPERTIES_FIRST` if so -- Records are... challenging as ordering is implied by record declaration, somehing POJOs don't have.

Perfect, can confirm that that works! Tricky indeed, I don’t mind disabling the creator-first explicitly here 🙏

That's indeed what I'm doing manually now :)
Would your recipes also account for configuration in a Spring application.properties or .yml, rather than in code? I deleted a bunch of config there as well
application.property

Another quick question before I raise an issue: it seems like alphabetical sorting of properties stopped working for records, while it functioned as expected in 2.x.
Is this a feature or a bug? We have HMAC-related functionality that relies on this, so a test caught it.

Hey, SerializationFeature.WRITE_DATES_AS_TIMESTAMPS is actually DISABLED in 3.0 rather than enabled, right?

Great work on the 3.0! I'm currently prepping for a Spring Boot 4 upgrade where I want to jump on Jackson 3.0, and I can delete a lot of config and customizations!

And then decide if you want to upgrade to Jackson 3 🤨

I guess you need one or the other, otherwise there’s no auto-configuration

Did you change your starter dependencies to the new modularized ones, or are you using the "classic" dependencies for now?

Explains why after restarts we always see values go up significantly to only go back down after several hours: the more “rare” tag values you accumulate, the worse the error will be…
This ends up looking like this: .avg is ca. 30% of what the real value should be, feels like being lied to for years

Very nice, I always enjoy the talks you do together! Good info to know what to expect when upgrading (which we’re planning to do soon after the release)
