add v0.7 release notes to the Parade of Release Notes and reverse the chronological order

Documentation

The Basics

  • architecture.txt: the design decisions that have given the grid its current shape
  • UseCases: the ways in which Tahoe should be useful
  • webapi.txt: everything you need to know to use Tahoe from your own program
  • roadmap.txt: how the functionality has been incrementally improved so far, and what improvements we plan to make next
  • codemap.txt: the software design and the organization of the source code
  • configuration.txt: how to configure a tahoe node and what persistent state it creates

The Parade of Release Notes

  • the release notes announcing v0.7 on January 8, 2008, featuring decentralized directories and mutable files, a FUSE interface, and new open source licensing options
  • the release notes announcing v0.6.1 on October 15, 2007, including packaging, usability, and performance improvements
  • the release notes announcing v0.6 on September 24, 2007, including improved performance and packaging
  • the release notes announcing v0.5.1 on August 23, 2007, fixing a security problem in the Web API
  • the release notes announcing v0.5 on August 17, 2007, including the Web API and the command-line interface

  • the release notes announcing v0.2, the first public release, on May 2, 2007 and giving a general overview of why the Tahoe project exists

Detailed Design Docs

  • mutable.txt, explaining the interesting crypto tricks that go into secure distributed mutable files
  • FileEncoding?, explaining how we turn files into shares, with verifiable hashes; This is mostly concerned with chunking and Merkle trees.
  • ShareEncoding?, explaining how we turn a chunk into shares: Reed-Solomon, FEC, that stuff

Outstanding Issues

  • PeerSelection, explaining how a Tahoe node chooses which other nodes to use for uploading and downloading files (which raises some unsolved issues in balancing scalability, robustness, performance, and simplicity)
  • ChangingFilesWhileCopyingThem? : what are the semantics of the "upload" action? the upload takes non-zero time: what happens if the file is changed during that time?
