Valuable News – 2018/09/22

Today the amount information that we get using various information streams is at massive overload. Thus one needs to focus only on what is important without the need to grep(1) the Internet everyday. Hence the idea of providing such information ‘bulk’ as I already do that grep(1).

New release brings lots of third party security updates, plugin updates and minor enhancements in overall system reliability.

They will soon also begin the migration work for FreeBSD 11.2 for 19.1, but please keep in mind that they will be issuing security advisories to 11.1 when they arise even beyond the original end of life policy.

DragonFlyBSD Defaulting To GCC 8 Compiler, Replacing The Old GCC 5  

With the last of the major GCC 8 build issues of the DragonFlyBSD code-base resolved, this BSD operating system has switched to using this latest stable release of the GNU Compiler Collection by default.

This is a big default change for DragonFlyBSD as up to now its default compiler was using the several year old GCC 5. With the default move to GCC 8 comes many optimizations, particularly for newer Intel and AMD CPU microarchitectures. This is especially good news for AMD Zen "znver1" CPU users. There is also support for newer C/C++ language features and many other enhancements as we've covered over the past few years.
