bzr 0.10 RC1

Bazaar-NG (or bzr) is a project of Canonical to develop an open source distributed version control system that is powerful, friendly, and scalable.
Version control means a system that keeps track of previous revisions of software source code or similar information and helps people work on it in teams.
bzr is still at a fairly early stage of development but has been self-hosting since March 2005 with no loss of data.
bzr is the next-generation distributed version control.
Main features:
- Written in Python (but nevertheless fast and easy to install.)
- Runs on Linux, Windows and Mac OS X, or any system with a Python interpreter. (Primarily tested on Ubuntu.)
- Free software, released under the GNU GPL.
- Designed to play well with others: can be called by IDEs, editors, web tools, GUIs, etc through either a Python API or a shell interface, and possibly a C interface in the future. Can support workflow/process tools built on top.
- The user interface is simple and familiar to people with experience from CVS or Subversion: add, mv, diff, status, commit, log, merge, etc all do what you would expect.
- Offers a choice between centralized and decentralized work within a single project: when in the office, you can work on a shared central branch. For experimental changes or offline work you can make a branch on your laptop and merge back in later.
- Preserves history; any previous revision can be recreated. History can be GPG-signed to protect against man-in-the-middle attacks, bad mirrors, server intrusion or data corruption.
- Just one .bzr directory at the top of the tree; it doesnt clutter the tree or get in your face. No wierd ++file--names--0.
- Tracks file and directory renames and merges across them.
- Powerful Python plugin system for adding new commands, protocols, formats, or site policy.
Enhancements:
- merge now takes --uncommitted, to apply uncommitted changes from a tree.
- Moderate performance improvements, particularly on large trees.
- Compatability with diffutils 2.8.4. bzr uncommit preserves pending merges.
- Active FTP support has been fixed.
- TZ=UTC is handled properly when reading/writing revisions.
- GPG_TTY is used to allow gpg --cl to work with gpg-agent in a pipeline (passing text to sign in on stdin).
- External diff does the right thing for binaries even in foreign languages.
