Download SVN Snapshot

SVN Snapshot: Bochs, like many other open source projects, uses SVN (Subversion) to keep track of source code. Unlike the current release, the SVN version of the sources contains everything the developers have written to this date, and it can change daily (or even hourly). As a result, the SVN version of Bochs will have more features and bug fixes than the release, but also it may be somewhat less stable. You can decide if you prefer to go exploring and try out our newest code, or stick with the better-tested release.

The SVN snapshots are provided as a convenience only. Of course, you could also get the same information using SVN itself. Some of the benefits of using SVN directly are: you can get any release or version, view the log messages that say what files were changed, and make patches very easily with "svn diff -u".
