You can download the new version, as usual, from the idea itself (settings-> plugins), BUT
You forgot to update the version
in the repository (I already told them about it and I hope they will fix it), so if you had version 0.4 you need to do aninstall, and then install a new version.
Of the new features, I noticed only support 1.5 and things related to this (like AVD), a bug with the 'skipping index file ...', alas, is not fixed :(
