Nightly Builds
Disclaimer
The nighly builds are created automatically each night using the latest revisions of the source files from CVS. If you don't have problems with the normal release versions of FileZilla 3, nightly builds may not be of much use for you. (Remark: FileZilla 3 hasn't been released yet.) Nightly builds are especially useful to see if certain bugs have been fixed or to test new features.
Since the source in CVS for the nightlies is work in progress, builds may fail or may not work properly. Use them at your own risk!
