"New front end login box" (newloginbox) is now part of the core . You might know the login content element from the days before newloginbox. Back then it was a simple way (with not too many features) to make it possible for web site visitors to log in to restricted areas of a website. Since the first release of newloginbox this core content element lost more and more importance as the competing extension offered way more features. With this release the newloginbox comes back home to the core and sees its rebirth as "felogin" system extension. This new extension now completely replaces the former login content element by extracting the needed functionality from newloginbox. As you might know, too newloginbox also consisted of a second part, the user listing plugin. You can find this plugin as a new extension in TER, called "feuserlisting". This means that with the final release of TYPO3 4.2 newloginbox will be rendered obsolete and felogin and feuserlisting together take its place. Kudos concerning this goes to Steffen Kamper and Stefan Strasser for maintaining the former newloginbox and moving it back home into the core.
Kasper Skårhøj implemented the long awaited feature to move elements in workspace. Additionally Workspace "swapping" for "New"-placeholders and "Deleted"-markers is now supported. Previously, both types would be published, not swapped. An option was added to completely turn off page and branch versioning (which are deprecated for TYPO3 4.2+). The whole Workspace can be previewed now for users with no backend login by a simple link you can email. Basically this is the same functionality as the preview link for individual pages available from the Web>Versioning module. You can find this function in User>Workspace (Workspace manager).
