In this major new release, we've +added deep-immutable directories (i.e. permanent snapshots), +greatly increased performance for some common operations, and +improved the help text, documentation, command-line options, +and web user interface.

You can easily and securely share chosen files and +directories with others. We believe that the combination of erasure coding, strong encryption, Free/Open Source Software and careful engineering make Tahoe-LAFS safer than RAID, removable drive, tape, on-line backup or other Cloud storage systems. -This software comes with extensive tests, and there are no -known security flaws which would compromise confidentiality or -data integrity in typical use.
