Firefox 15 Beta Tackles Memory Leaks

Mozilla has released a beta version of the next version of its Firefox browser with better memory management and significant speed improvements.
"Firefox 15 prevents most memory leaks caused by add-ons, including Firebug," Nicholas Nethercote writes in a Mozilla blog. Firebug is a Firefox add-on for debugging web pages.
"For many users with add-ons installed, this will significantly reduce Firefox’s memory consumption, without requiring upgrades to those add-ons," he adds. "For those users, Firefox 15 is likely to be faster (sometimes drastically so) and less likely to crash, especially if they have multiple add-ons installed and/or keep Firefox running for a long time between restarts."

Slackware Linux 14.0 Beta

Slackware "Current" is now beta - that's according to Patrick Volkerding who wrote the following in today's changelog: "Howdy! Lots of shiny stuff here, including the long awaited Xfce 4.10. Thanks to Robby Workman for the initial set of build scripts, and lots of testing (plus some very helpful notes about things such as the proper build order). I'm calling this a beta (finally!), and it's really very close to what we expect to release. Test away." The changelog also includes a long note on udev: "Well, udev in this development cycle has certainly been interesting. A fair number of odd bug reports have been coming in, and we hadn't really been able to get a handle on the source of the issues. Quite some time ago we started testing udev-182, and noticed that it caused some issues with the persistent net and CD rules." As always, there are no official installation media, but recent builds of unofficial DVD images can be had from here: slackware-current-17_Jul_2012-DVD.iso (2,422MB, MD5), slackware64-current-17_Jul_2012-DVD.iso (2,382MB, MD5).

Arch Linux 2012.07.15

Pierre Schmitz has announced the release of Arch Linux 2012.07.15 "netinstall" CD image. Since Arch Linux is a strictly rolling-release distribution, this release merely provides an updated system installer and it does not represent a new Arch Linux "version" in the traditional sense of the word. From the announcement: "New CD images containing a current Arch Linux snapshot have been released. Most notable change is that AIF (the Arch Installation Framework) is no longer included but instead some simple install scripts are provided to aid in the installation process. This means that a menu driven installer is no longer available and we rely more on documentation to guide new users. Instead of six different images we only provide a single one which can be booted into an i686 and x86_64 live system to install Arch Linux over the network." Download the new Arch Linux "netinstall" CD image from here: archlinux-2012.07.15-netinstall-dual.iso (483MB, MD5, torrent).

Linux Mint 13 "Xfce"

Clement Lefebvre has announced the availability of the Xfce edition of Linux Mint 13, codename Maya. From the what's new page: "The highlight of this edition is the latest Xfce 4.10 desktop, which features the following improvements: online documentation; application finder; multiple rows and deskbar mode in the panel; actions plugin; MIME type editor; single-click operation, automated background image cycling and thumbnail rendering on the desktop; edge-tiling in the window manager. In the past, the xfapplet plugin made it possible for Xfce users to run GNOME applets within the Xfce panel. After talking to the MATE and Xfce developers, we updated this plugin and it now supports MATE applets. Among the many MATE applets that can now run in Xfce, mintMenu is probably the most popular. Improvements were made to mintMenu so that it could support Thunar, the Xfce Settings Manager and other aspects of the Xfce desktop...."
