Updating flatpak on linux mint

when updating the flatpak on mint get the following message:

Info: org.kde.Platform//6.6 is end-of-life, with reason:
   We strongly recommend moving to the latest stable version of the Platform and SDK
Applications using this runtime:
   me.timschneeberger.jdsp4linux

Does it means that the flatpak must be updated by the developer  and use a newer version of the sdk?
