### Customizing Trusted Certificates ([.kt][CustomTrustKotlin], [.java][CustomTrustJava])

_2024-04-17_

 *  Breaking: Move coroutines extensions to okhttp3.coroutines. Previously this artifact shared the
    `okhttp3` package name with our core module, which is incompatible with the Java Platform Module
    System.

 *  Fix in okhttp-coroutines: Publish a valid artifact. The coroutines JAR file in 5.0.0-alpha.13
    was corrupt and should not be used.


## Version 5.0.0-alpha.13
