<b>SVN Snapshot:</b>
|
|
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".
