New OnionShare has been released.
Better features than ever!
Summary excerpt:
Now when you open OnionShare you are presented with a blank tab that lets you choose between sharing files, receiving files, hosting a website, or chatting anonymous. You can have as many tabs open as you want at a time, and you can easily save tabs (that's what the purple thumbtack in the tab bar means) so that if you quit OnionShare and open it again later, these services can start back up with the same OnionShare addresses.
So with OnionShare 2.3 you can host a few websites, have your own personal anonymous dropbox, and securely send files to people whenever you want, all at the same time. Under the hood, the addition of tabs also makes OnionShare connect to the Tor network faster, especially if you're using a bridge.
