Slackware 14.2 release notes. Thu Jun 30 22:37:15 UTC 2016 Hi folks, Historically, the RELEASE_NOTES had been mostly technical information, but once again Robby Workman has covered the important technical details in CHANGES_AND_HINTS.TXT. Thanks! After jumping ahead through various Linux kernel branches over the course of this development cycle, we ended up on the 4.4.x branch and decided to stick with it. Greg Kroah-Hartman's announcement back in October that the 4.4 series would be getting a long-term support for two years helped to cement this decision and should be good news for anyone wanting to keep a maintained stable kernel on their system. As usual, the kernel is provided in two flavors, generic and huge. The huge kernel contains enough built-in drivers that in most cases an initrd is not needed to boot the system. The generic kernels require the use of an initrd to load the kernel modules needed to mount the root filesystem. Using a generic kernel will save some memory and possibly avoid a few boot time warnings. On the 32-bit side of things, there are both SMP (multiple processor capable) and non-SMP (single processor) kernels. The non-SMP kernel is mostly intended for machines that can't run the SMP kernel, which is anything older than a Pentium III, and some models of the Pentium M that don't support PAE (although it seems that these might support PAE but just lack the CPU flags to advertise it -- try booting with the "forcepae" kernel option). On 32-bit, it is highly recommended to use the SMP kernel if your machine is able to boot with it (even if you have only a single core) because the optimization and memory handling options should yield better performance. If you'd like to try out the latest kernel branch, you'll find .config files for Linux 4.6 in the /testing/source/ directory. Slackware 14.2 has support for systems running UEFI firmware (x86_64 Slackware edition only). Packages that help support UEFI include elilo, GRUB 2, and efibootmgr, and all of the installation media supports booting under UEFI, as do the USB boot sticks generated during installation. At this point there is no support for running the system under Secure Boot, but a dedicated user could add their own Machine Owner Key, sign their kernels, modules, and bootloader, and then use shim to start the bootloader. Documentation for installing on UEFI machines is provided in a README_UEFI.TXT found in the top-level Slackware directory. Slackware ISO images (both the ones available online as well as the discs sent out from the Slackware store) have been processed using isohybrid. This allows them to be written to a USB stick, which can then be booted and used as the install source. This works on machines running both regular BIOS as well as UEFI. Slackware 14.2 contains updated versions of both KDE and Xfce, and both of these have been split as much as possible into their component packages rather than larger bundles. This not only makes it easier to remove software that you don't need, but also makes it easier to maintain on our end. If something needs a patch, it's a whole lot easier to issue a patch for only the affected item. This saves storage space on the archive sites, and your time and bandwidth downloading the updates. Although Slackware does not ship the GNOME desktop, we can recommend a couple of places to look if you're interested in trying to add it to your system. The Dropline project ( http://www.droplinegnome.net ) will be putting together a set of packages for running GNOME 3.20.1 on Slackware. There's also the MATE desktop, which is a fork of GNOME 2.x. SlackBuild scripts are available to compile MATE packages for Slackware from http://mateslackbuilds.github.io - thanks to Chess Griffin and Willy Sudiarto Raharjo for making this option available. Need more build scripts? Something that you wanted wasn't included in Slackware? Well, then check out slackbuilds.org. Several of the team members work on the scripts there. There's a community driven site for Slackware documentation, http://docs.slackware.com -- check it out, and join in to share your knowledge! Thanks to the rest of the team (and other contributors) for the great help -- Eric Hameleers for major work on the KDE SC packages, init scripts, installer, documentation (especially getting docs.slackware.com up and running), and all the extra packages like multilib compilers (read more here: http://alien.slackbook.org/blog/), Robby Workman for following X.Org, eudev, NetworkManager, wicd, Xfce, and tons of other projects, building and testing all that stuff, writing documentation, his work with the team at slackbuilds.org, and lots of package upgrades, Piter Punk for slackpkg work, Stuart Winter for more updates to linuxdoc-tools, slacktrack, and for all kinds of fixes throughout the installer and system (he finds my bugs all the time while porting packages to ARM for the Slackware ARM port: http://www.armedslack.org/), Vincent Batts for keeping Ruby working well and other miscellaneous fixes, Heinz Wiesinger for working on PHP, MariaDB (especially!), icu4c, LLVM, and lots of other stuff, Amritpal Bath for various bugfixes and helping with release torrents, mrgoblin for testing RAID, bluetooth, and being a master of regex. Other very honorable mentions go to Alan Hicks, Erik Jan Tromp, Karl Magnus Kolstø, Mark Post, Fred Emmott, and NetrixTardis, and anyone else I'm forgetting (including the other team members who contributed little fixes and suggestions here and there along with general moral support). Special thanks to the folks who mailed in bug reports (and fixes) and helped collaborate on this release. This was another great release cycle for community participation, especially on the LinuxQuestions.org Slackware forum. Thanks for the help, for keeping this project fun, and making it possible for us to keep up with the rapid pace of Linux development. Thanks to Andrea and Briah, too! Have fun! Pat Volkerding
