Linuxlookup.com is reporting on the release of Gentoo Linux 2006.1. Building on the strengths of previous releases and featuring all of Gentoo's well-documented flexibility, performance and portability, this release is now available on all supported architectures. The most popular architectures now use GCC 4.1, glibc 2.4 and baselayout 1.12.1, as well as including a new profile layout, with seperate desktop and server profiles.

Upgrades aren't necessarily that simple, even in Gentoo. Firstly, one ought to update the /etc/make.profile symlink to point to the appropriate portage profile. Secondly, consider the gcc upgrading guide:
http://www.gentoo.org/doc/en/gcc-upgrading.xml
It specifically states that there have been some incompatible ABI changes between binaries produced by gcc-3.4 and gcc-4.1 - presumably the C++ runtime library again. In any case, this is an important issue if the user decideds to explicitly activate the new instance of gcc with the gcc-config tool after installing gcc-4.1. As the majority of upgraders will most probably want to do exactly that, the most sensible procedure would be to to carry out the instructions mentioned in the guide: upgrade gcc, switch/activate, emerge libtool, emerge -e world then optionally remove the older version of the compiler. If you think about it, running emerge -uDN world would be a complete waste of time unless one intended to stay with gcc-3.x for the forseeable future ...
Finally, depending on the exact circumstances and not necessarily relating to the variations between official release snapshots, upgrades of certain packages can sometimes entail particular steps to "clean up" afterwards. This might entail running perl-cleaner, python-updater and/or revdep-rebuild (I'm sure I don't need to mention dispatch-conf/etc-update).
Anyway, this looks like a good release - well done to the Gentoo release engineering team

To clarify, it's only necessary to do that about once or twice a year. Other than that, gentoo upgrades are indeed (mostly) rolling. Anything more complicated than that is often (though not always) due to upstream changes the gentoo people have little control over, e.g. changes in gcc or the switch to modular X.
However, it would be my advice (to anyone installing or reinstalling [why?!] Gentoo on a new box who wants to take it) to always use the very latest official release of the install CD's for your architecture.

Also, I forgot to add that when switching gcc versions one really ought to rebuild the kernel and kernel modules in their entirety. The kernel does not like having portions of itself built with different compilers. I've seen this happen quite often with people who build external modules (such as nvidia-drivers), expecting to be able to use the modules with a kernel that was originally compiled with an older gcc version. It doesn't work. Although it's easily dealt with, the point is that there is no "automagic" way of taking care of all of this.

"The first killer app was VisiCalc. This early spreadsheet turned the Apple II from a hobbyist toy to a business computer. VisiCalc came with room for improvement, though. In addition, a new architecture and operating system, the Intel-based IBM PC and MS-DOS, also needed a spreadsheet to be taken seriously. That spreadsheet, released in early 1983, would be Lotus 1-2-3, and it would change the world. It became the PC's killer app, and the world would never be the same. On May 14, IBM quietly announced the end of the road for 1-2-3, along with Lotus Organizer and the Lotus SmartSuite office suite. Lotus 1-2-3's day is done." Impressive 30 year run.
"There's a disconnect between how Apple CEO Tim Cook sees his company's tax strategies and how some members of the US Senate view it. That became clearer than ever today after Cook and two other Apple executives testified before Congress, explaining why they're holding most of their international income in Irish subsidiaries like Apple Operations International, which declare no tax residency anywhere in the world. AOI hasn't filed a tax return anywhere in the world for the last five years, yet it earned $30 billion in income from 2009 to 2012, according to a Senate report released yesterday." Just because something is legal, doesn't mean it's just. Apple, Google, Microsoft, and many more - these companies might not be breaking any laws, but it's obvious to anyone that what they are doing is scummy.
The new WebKit Opera for Android has been released. "Opera 14 for Android is built on top of Chromium 26, with a total overhaul of the UI in native code, making it fit well with the latest Android design guidelines. Go get the build from Google Play or point your browser to m.opera.com, and give it a spin!"
The Verge pointed me to a blog post by Leap Motion - which reveals how their Kinect-like motion control works with Windows 8. "From the second you plug in your Leap Motion Controller, you'll be able to browse the web and interact with your computer just by moving your hands and fingers in the air. With Leap Motion technology and Windows, you can do everything that's possible with multi-touch inputs - without actually touching anything. This also means that existing applications in Windows 7 and 8 will respond to your natural hand and finger movements. Soon, we'll show you how Leap Motion will work with Mac OS X." Quite cool.
PocketNow interviews Marc Dillon, and there's an interesting note about why Jolla is keeping the display properties under wraps: "We're leaving some of those details out because we do understand that there are a lot of really big players in the market and they tend to take certain components in the market and dominate them. We created the ability to actually be able to run Sailfish on multiple hardware displays and be able to swap components, so this is part of the demand and supply planning phase. We are committed to this industrial design which is a 4.5-inch display, an 8 megapixel camera on the back and a front-facing camera at the front, and the exact specs of the display we'll provide when we're close to delivery." Something you rarely hear anything about.
"This is my NeXTstation Turbo Color booting the Mac System 7.1 Operating System using a hardware add-on called 'Daydream'. The Daydream has a Mac ROM and a few custom ICs in it and hooked up to the NeXTs DSP port. Turns your NeXT into a full fledged 68k powered Mac." So cool.
"The NetBSD Project is pleased to announce NetBSD 6.1, the first feature update of the NetBSD 6 release branch. It represents a selected subset of fixes deemed important for security or stability reasons, as well as new features and enhancements. Please note that all fixes in the prior security/bugfix updates (NetBSD 6.0.1 and 6.0.2) are also in 6.1."
"At the end of a week in which Electronic Arts confirmed it wasn't developing a thing for the Wii U, one of the software engineers in EA Sports' Canada studio, in a series of since-deleted tweets, disparaged the console as 'crap' and suggested Nintendo should give up on hardware altogether. 'The Wii U is crap. Less powerful than an Xbox 360. Poor online/store. Weird tablet', tweeted Bob Summerwill, listed as a senior software engineer at EA Canada, in a reply to a tweet posting a link about EA's no-Wii U news. 'Nintendo are walking dead at this point'." The Wii U is turning into the 21st century's Virtual Boy.
"In NixOS, the entire operating system - the kernel, applications, system packages, configuration files, and so on - is built by the Nix package manager from a description in a purely functional build language. The fact that it's purely functional essentially means that building a new configuration cannot overwrite previous configurations. Most of the other features follow from this." Interesting approach. A Linux distribution, sure, but with some very refreshing ideas about system configuration.
Appfour added, among other features, C/C++ support to its new version of AIDE. From Android-IDE, "Now you can write parts of your app or your whole app in C/C++ on your device. AIDE supports the Standard Android NDK toolchain (GCC 4.6 + Bionic, STL, ...). No changes are necessary if you want to build an app developed on a PC with Eclipse. C/C++ development is fully integrated: Build errors appear in the error list and files can easily be navigated to with Go to file. The editor supports C/C++ syntax highlighting."

Isn't it a rolling release anyway?
Could have just grabbed 2006.0 and emerge vauD world
Unless you have really new hardware that wasn't detected by 2006.0 CD
