IDE 1.8.7 can't see the wifi ports

After its release I quickly bought a couple of Yun Rev 2. With previous 1.6.5 release I could see all the installed boards. Now, with the boards up and running, wifi connected, the IDE doesn't show any wifi port, either with the old Rev1 or with Rev2.
If I run the web editor all the ports are ok.
Did I miss anything in the installation ???
Thanks.
