Panic has updated its Transmit FTP client ( to version 4.0, which offers a speed boost, streamlined interface and more.

With the new Transmit Disk feature, you can now mount any of your favorites in the Finder itself, even if Transmit’s not running. You can drag files to your SFTP server, save a small graphic to your Amazon S3 bucket directly from Photoshop, or roll your own iDisk-like backup volume.

Transmit 4.0 is compatible with Mac OS X 10.5 or later and costs US$$34. Upgrades from version 3.x are $19.
