PMS Latest Version not Compatible with DS213j?

Hello,

I have a Synology DS213j and I'm running the version 0.9.16.3 downloaded from Synology Packadge Center. But, in Plex website the current version is 1.1.4.2757-24ffd60 and when I download this version and try a manual install I have an error saying that the version is not compatible with my Synology.

I tried both ARMv7 and Intel versions, both with the same error.

Is that normal? Is my Synology DS213j too old for the new version?

Thanks

Gustavo
