After just one alpha release two months ago the beta of Slackware 15.0 was announced in the ChangeLog yesterday. This release comes on April 12, which is the International Day of Human Space Flight and this year it's also a round anniversary - 60 years since then. I'm slacker and I'm also interested in astronomy and space exploration, so it doubled the fun for me :-)
There were no build regressions with the upgraded to 10.3 GCC compiler, but there is no fix "for the illegal instruction issue with 32-bit mariadb" yet, which seems like the only blocking problem before the stable release unless of course other issues arise.
Hopefully the new major and stable release is coming, but when it would arrive knows only one man and you know who ;-)
Stay tuned until then and of course test the new beta!
