Android : Proguard build is failing for joda time

Question

I am getting the following error when I build the app with proguard. This failure is new. I updated some of the libraries used in the app to latest (including the target and compile sdk version to 30)but the joda library version is not changed. It is implementation 'net.danlew:android.joda:2.8.2' Any idea why this error is coming now and how it can be resolved. I already have the rule -keep class org.joda.** { *; } in my progurad rules.

EDIT

Updating joda version to the latest 2.10.9.1 fixes the issue. I am not adding this as answer as I wanted to know why this error appeared all of a sudden? Can any other version update can lead to this.
