Dropbox 2.2.3 RC has been released. While the Windows version has new updates and bugfixes than the previous release, Dropbox 2.2.2 RC, the developers totally ignored the version for Linux.
So, Dropbox 2.2.3 RC for Linux is the same as Dropbox 2.2.2 RC for Linux (but the source code’s archive was renamed from dropbox*-2.2.2.tar.gz to dropbox*-2.2.3.tar.gz)
Awesome, isn’t it?
