20 Jun 2015: We had a couple of releases since December. In version v0.4.1-alpha & v0.4.2-alpha we added a new 'Preferences' dialog to add/remote plugin and a copy-link feature in the GUI. With version v0.4.3-alpha, we released our first Mac OSX version, added a history browser to the GUI and made plugins updatable. For version v0.4.4-alpha, we rewrote the Syncany API on the website, added 3rd party plugins and update checks for the application and plugins. In version v0.4.5-alpha, we added automatic OAuth token handling, added optional transfer manager features, added a default .syignore file, and much more. In all releases, we also fixes countless bugs! Check out the releases page for more details.

28 Dec 2014: We've reached another milestone. The Syncany core feels more stable by the minute. We released v0.2.0-alpha, v0.3.0-alpha, v0.4.0-alpha, with v0.4.0-alpha being the best release we have ever had. The GUI (tray icon and 'New folder' wizard) works quite well. You can see it in action on our YouTube channel. We also made a couple of new plugins for Flickr (encode data in images, video here), Dropbox, OpenStack Swift and RAID0. Beta is just around the corner!

20 Oct 2014: In releases v0.1.6-alpha, v0.1.7-alpha, v0.1.8-alpha, v0.1.9-alpha, v0.1.10-alpha, v0.1.11-alpha and v0.1.12-alpha, we have added a Samba plugin, a working REST/WS-based daemon, a first version of the GUI (cross-platform demo on YouTube), and written an awesome user guide. We've also created an APT archive for Debian/Ubuntu users, and made a Windows installer includes the GUI plugin. And of course, we've fixed countless bugs, slowly approaching stability. Unfortunately, we're still not there yet -- we still have some nasty bugs ...
