DevConf.cz 2021

With its innovative application composition process, Quarkus exposes different kinds of APIs to the applications both at build time and runtime. These API branes, like the ones proposed by string theory, occasionally collide and a new universe full of quarks is born - Quarkus is released. Why do the laws of physics work the way they do in this new universe? Very much depends on the way the branes collided - what versions of the libraries went into the release and how much their API and behavior has changed.

In this talk we're going to take a look at how Quarkus has started to use Revapi to try and understand, report on and process the API changes that happen in both Quarkus itself as well as the libraries it incorporates and makes available as all of them evolve across the releases.

What you'll learn:
* where the APIs are in Quarkus
* how they're reported on
* what measures are taken against accidentally changing the API
* maybe some fun ways in which API can be broken, if time permits
