It's been a while since we heard from the developers at Magnetk, but they've just released version 1.3 of Expandrive with some new functionality. They're calling it a beta to be safe, but it seems to just be cautious labeling; 1.3 has been very stable for me thus far. As a quick review, Expandrive allows remote SFTP volumes to be mounted in the local filesystem (similar to what's possible with MacFUSE, but with several stability and speed improvements). The biggest change in version 1.3 is probably the inclusion of FTP and FTPS as an addition to the SFTP capabilities. While it may seem strange to some, there are certainly still circumstances where this could prove very useful.
UPDATE: the developers have clarified for me that the 1.3 release is not in beta, only the FTP/FTPS capability.
Among the other features the developers are excited about is a new system for testing network state. One of the things I like about Expandrive is its ability to seamlessly maintain a connection on my laptop when I shut it, move it and change wireless networks. Well, that capability has been improved at the system level to better detect network availability, IP address and sleep state, and I'm seeing really stable performance with it.
A second appcast has been added to support beta releases (Magnetk says they have a lot of new stuff coming up), and users can switch to it in the Updates section of the preferences. Version 1.3 resets the 30 day trial period, so if you've previously tried it and passed, you'll be able to take the new version for a 30-day spin. The trial version is available for download ($29USD to register), and the upgrade is free for current users. Release notes are available here.
