This is a major change, and so the next release will be Jakarta Mail 2.0.0, which will be included in Jakarta EE 9. Applications should be able to switch to this new version fairly easily by just changing all imports that use javax.mail.* to instead use jakarta.mail.*. Note that SNAPSHOT and Release Candidate versions of Jakarta Mail 2.0.0 are already available.

                    <name>Jakarta Snapshots</name>
