In 2018, we introduced an enhanced java wrapper for liblinphone, based on a code generator (see our old newsletter here).
Since then, we have been maintaining both this new wrapper (automatically generated) and the legacy one (manually wrapped), in order to give our customers enough time to migrate to the new wrapper.
We have now decided to discontinue the old Java wrapper, and linphone-sdk version 4.5 will be the last one to support both wrappers.
