The recent updates for the development and stable versions of Dropbox incremented the build numbers to 1.5.46 and 1.4.21 respectively.
The Experimental version, which is also a release candidate for the next stable, features an unspecific number of small repairs. However, a more significant problem has also been addressed on OS X and, at the moment, the web login should no longer launch an HTML editor instead of a web browser.
A previous update repaired a rare bug that would cause the client to re-index files continuously.
As for the current stable revision, the only modification made by the developer is the double-click installer on Mac systems.
Previous releases include fixing up problems with icons on Ubuntu 12.10 (menu icon) and Windows 8 (system tray icon), as they would not be visible.
