Releasing

Prerequisites

Java 17+ (required by Gradle 8.2 and the build toolchain)
A GPG key set up locally and made available to the Gradle signing plugin as per https://docs.gradle.org/current/userguide/signing_plugin.html#sec:signatory_credentials
A Central Portal token from https://central.sonatype.com (go to Account → Generate User Token)

Checkout latest master.
Make sure you are on a clean master and everything is pushed.
Run ./gradlew clean test and make sure everything passes.
Update the version in gradle.properties and the baselineVersion in binary_compatibility.gradle to the version being released. Commit, push via PR, and tag the merge commit.
Run ./gradlew publishAggregationToCentralPortal -PSONATYPE_NEXUS_USERNAME=<token-username> -PSONATYPE_NEXUS_PASSWORD=<token-password>.
Log in to https://central.sonatype.com and verify the deployment. Since publishingType is USER_MANAGED, you need to manually publish the deployment from the portal UI.
Add a description of the new release at https://github.com/spotify/mobius/releases.
Once the new set of artifacts is available on https://repo.maven.apache.org/maven2/com/spotify/mobius/, update the baselineVersion property in binary_compatibility.gradle to the version that was just released.
Update the version in gradle.properties in the master branch to the next version.
