Dropbox 1.5.7 Experimental Build adds Mountain Lion support

If you are a user of the file synchronization service Dropbox, you may know that the developers are releasing experimental versions regularly in the forum. These experimental versions are like public beta versions. They often ship with additional features and improvements that the developers want to test using a larger audience.

The latest experimental version of Dropbox has been released yesterday, bringing the version of the client to 1.5.7 for users who install it over their existing Dropbox installation or on  a new computer system. The experimental build is available for all supported operating system. Existing Dropbox users can simply install it over their current version on the system.

Dropbox recommends to make a backup of all files that get synchronized on a computer where the new experimental build is installed on.

Dropbox 1.5.7 ships with the following new features:

• This build improves support for the Apple Macintosh OS 10.8 Mountain Lion operating system
• Windows users can now drag and drop files and folders on the Dropbox Windows shortcut to move the files into the Dropbox
• The Lan network card detection code has been rewritten to improve the feature. The developers note that users may experience issue with the new feature.

Most Dropbox users who have commented on the release announcement in the Dropbox forum reported no issues with the new release.

Dropbox 1.5.7 is not the only experimental version that the developers have released in recent time. The latest stable build of the client is 1.4.9, and a total of three additional experimental builds have been released in the meantime.

These versions feature performance improvements, a number of fixes, support for Korean and a number of smaller changes.

It is not recommended to install the experimental builds on productive systems unless you create regular backups of the systems and the files that Dropbox synchronizes. It is likely that Dropbox will release the new version in the near future.
