Adobe released updated versions for their Flash Player plugins halfway February. I missed those initially, but today I fixed that.
The Slackware packages for version 188.8.131.52 of the flashplayer-plugin (NPAPI plugin for Mozilla based browsers) and the chromium-pepperflash-plugin (PPAPI plugin for Chromium based browsers) are available in my repository now.
Also recently there was a new release for the IcedTea framework: version 3.11.0 compiles the latest Java 8, to be specific you will get OpenJDK 8u201_b08. This release syncs this OpenJDK build to the January 2019 security fixes for Java.
If you want to compile OpenJDK yourself you will need apache-ant as well.
Note about java usage:
My Java 7 and Java 8 packages (e.g. openjdk7 and openjdk… or openjre7 and openjre) can not co-exist on your computer because they use the same installation directory. You must install either Java 7 or Java 8.
Remember that I release packages for the JRE (runtime environment) and the JDK (development kit) simultaneously, but you only need to install one of the two. The JRE is sufficient if you only want to run Java programs (including Java web plugins). Only in case where you’d want to develop Java programs and need a Java compiler, you are in need of the JDK package.
Here is where you can download the Slackware packages for Flash (flashplayer-plugin and chromium-pepperflash-plugin) and Java (openjre/openjdk):
