AlienBob's build of Chromium for users of 14.2 has for a long time been appreciated, and it is understandable support for 14.2 has to come to an end.
Here just for information for those on 14.2: it is not that hard upgrading 14.2 to a "current 20180310" based on the 4.4 kernel that will run AienBobs 15.0 Chromium series, without the need of reinstall. If using the 6 year old "current" kindly hosted at:
https://ftp.radix.pro/slackware/
and rebuilding and installing the essential libraries using the provided gcc 7.03 and (mostly) the provided Slackbuilds the resulting "hybrid" will run AlienBobs 15.0 Chromium, the latest Palemoon, will build Geany 1.38 et.c.
In that way modifications, symlinks et.c. done on 14.2 will be preserved. A few apps, e.g. Blas and Lapack (depending on GCC 5.5) has to be rebuild, but otherwise a transition should work.
A "hard metal" backup before such an adventure is of course essential, where "partition image" from Hireens boot CD works for me (might not work with UEFI partitions?).
The main problems for me by upgrading was mainly with Pango where version 1.40.4 worked for me. Some .la files was occasionally not installed by "make install" and had to be copied by hand (with fontconfig2 ?, I don't remember). Also one of the SlackBuilds had to be modified by disabling building of documents.
Perhaps not for the faint-hearted, but with a good back-up should be OK.
