This is the successor to Allmydata.org "Tahoe" Least Authority
-Filesystem v0.9, which was released March 13, 2008 [1]. Since v0.9
-we've made the following changes:
-
- * Use an added secret for convergent encryption to better protect the
- confidentiality of immutable files, and remove the publically
- readable hash of the plaintext (ticket #365).
-
- * Add a "mkdir-p" feature to the WAPI (ticket #357).
+Filesystem v1.0, which was released March 25, 2008 [1]. This release
+fixes several serious issues in Tahoe v1.0, and improves the user
+interfaces. See the known_issues.txt file [2] and the NEWS file [3]
+for details.
- * Many updates to the Windows installer and Windows filesystem
- integration.
+COMPATIBILITY
-Tahoe v1.0 produces files which can't be read by older versions of
-Tahoe, although files produced by Tahoe >= 0.8 can be read by Tahoe
-1.0. The reason that older versions of Tahoe can't read files
-produced by Tahoe 1.0 is that those older versions require the file to
-come with a publically-readable hash of the plaintext, but exposing
-such a hash is a confidentiality leak, so Tahoe 1.0 does not do it.
+Tahoe v1.1 is fully compatible with Tahoe v1.0. v1.1 clients produce
+files which can be read by v1.0 clients. v1.1 clients can read files
+produced by clients of all versions >= v0.8. v1.1 servers can serve
+v1.0 clients and v1.1 clients can use v1.0 servers.
WHAT IS IT GOOD FOR?

malicious, the filesystem continues to work from the remaining
computers. You can also share your files with other users, using a

-and careful engineering makes the use of this software a much safer
-alternative than common alternatives, such as RAID, or traditional
-backup onto a remote server, removable drive, or tape.
