The Chromium 74 sources were released a few days ago by Google, and it comes with a long list of fixes for security issues.
I spent almost two months to investigate why the 32bit package could no longer be built (which is one of the reasons why there were so few updates in march and april – I only have a few hours every day that I can spend on Slackware these days) and had finally managed to compile a 32bit package for Chromium 73 in a 32bit chroot environment on a 64bit Slackware OS, and that package was online for one day…. and now I tried compiling the new release on a regular 32bit Slackware OS and that worked! No idea whether this is because of my modifications of the SlackBuild.
The packages for chromium-74.0.3729.108 are now ready for download from slackware.com or slackware.nl, or any other mirror.
I verified that the Widevine CDM (for Netflix movie streaming) is still working.
