Last week, Chromium 68 was introduced to the “Stable Channel” with lots of bugs fixed, many of those being security fixes (42 in total). And a few days ago an update was released, so I decided to build Chromium 68 for Slackware.
NOTE: starting with Chromium 68, the browser will show a “Not secure” warning on all HTTP pages. Google announced this in a blog post published on February 8th on Google’s Chromium and Online Security blogs.
You’ll find 32bit as well as 64bit packages for Chromium 68.0.3440.84 in my package repository. They are available for both Slackware 14.2 and -current. I have also updated the Chromium Widevine plugin to version 188.8.131.528. The older version refused to work with Chromium 68. Note that the Widevine plugin is available for 32bit just as for the 64bit browser, so even those running older computers (or those of you who are in need of a 32bit OS) can enjoy DRM movie playback.
For newcomers: Widevine is a Content Decryption Module (CDM) used by Netflix to stream video to your computer in a Chromium browser window. With my chromium and chromium-widevine-plugin packages you no longer need Chrome (or Firefox if you dislike that browser), to watch Netflix.
Also note (to the purists among you): even though support for Widevine CDM plugin has been built into my chromium package, that package is still built from Open Source software only. As long as you do not install the chromium-widevine-plugin package, your system will not be tainted by closed-source code.
I had rebuilt the libreoffice-5.2.4 packages for Slackware -current last week, because library updates in Slackware had broken the spreadsheet application ‘localc‘. And voila… not long afterwards the Document Foundation blog announced 5.2.5: “all users are invited to update to LibreOffice 5.2.5 from LibreOffice 5.1.6 or previous versions“. Today on the first of february, we can even witness the 5.3 release.
I am definitely not building packages right away for 5.3 but I did compile packages for 5.2.5 – albeit only for Slackware -current. I may or may not create these packages for Slackware 14.2 as well and then upgrade the -current package to 5.3. Depends on the other stuff I need to do.
These libreoffice packages are huge in size so please use a mirror for download, and take into account that only the master site and ‘bear’ will have the packages during the first 24 hours.
On another note, Chromium (and Chrome) 56 ‘stable’ was released. It’s nice to test the HTML5 feature set on a site like HTML5test and see that it is at the top of all the browsers up there (517 points, only Chrome 56 for Windows scores better because it supports speech synthesis).
Packages for Slackware 14.2 and -current are now available from my repository. No ETA for Slackware 14.1 packages, and perhaps it is time for people still using Chromium on 14.1 to upgrade to 14.2?
I have made new packages for the chromium browser and its widevine plugin. Chromium version 44 was released a bit earlier this week, and it took me a while to compile, because the new OpenJDK 7u85 and LibreOffice 5.0.0.rc3 packages were ahead of it in the build queue. Guess what… now that I am writing this blog article after uploading the packages for chromium-44.0.2403.89, I notice that there was a second release of Chromium 44 Stable… today. Which makes me wonder if there was a regression in the earlier source release.
That updated version 44.0.2403.107 may have to wait, because I will be unable to do a lot of Slackware related stuff until august; real life is catching up with me. If there are real useability issues with 44.0.2403.89, let me know and I will see if I can shift priorities or make the older 43.x packages available again. My initial (not exhaustive) testing showed no weirdness at least.
Regardless, it took a few iterations before I got the Widevine CDM adapter to compile properly. I had to look at my chromium-dev package’s history to remember what had changed in version 44. Once I applied that knowledge to the stable sources, it all began to come together. Netflix still works 🙂 … well, after you’ve installed/upgraded my chromium-widevine-plugin package of course. which contains the proprietary Content Decryption Module.
The new chromium source I compiled into a package, comes with several security fixes, and here are the CVE’s:

Geeks and Sci-Fi fans, as well as otherwise properly educated people, will recognize the blog title for what it is.
Chrome 42 is released. Big jump: a major version change. Mostly changes under the hood again it seems. The Chrome binaries for this version contain a new version of the PepperFlash plugin, which I have extracted for use with the chromium browser – see my earlier blog. The packages for Slackware 14.1 and -current are available for download so that you can enjoy the latest Chromium browser (and its optional Widevine plugin) in your trustworthy Slackware environment.
The new packages for my chromium and chromium-widevine-plugin packages both have version 42.0.2311.90 – indicating that they should be used together. The Widevine plugin reports itself as version “184.108.40.2066” in chrome://plugins – same version as in my chromium-dev 43 package.
You don’t have to install the Widevine plugin. Chromium without Widevine plugin is a pure and open source browser, even the Widevine “adapter module” inside the Chromium package is open source. The Widevine library itself is a closed-source Content Decryption Module (CDM) which therefore is not part of the Chromium package but separately packaged (after extracting it from Google’s binary download of the Chrome browser with the same version number). You would typically want to install the plugin if you have a Netflix subscription and want to watch your movies in a Chromium browser.
Chromium 41 is a major version upgrade with attention to security and performance. I could not find new functionality that needs mentioning though.
The new packages for my chromium and chromium-widevine-plugin packages both have version 41.0.2272.76 – indicating that they should be used together. The Widevine plugin reports itself as version “220.127.116.111” in chrome://plugins .

Have fun with it! For me, it is bed time after a long working week, and time to bake some good sourdough breads during the weekend. After the weekend I hope to take a look at the new KDE Applications 14.12.3 tarballs and TigerVNC. Considering the promise of sun and high temperatures during the weekend, I would rather spend time walking outside with my wife than spend time alone behind this computer 🙂
