The developers of TrueOS has made available version 18.03 STABLE. This release patches the Meltdown and Spectre vulnerabilities discovered earlier this year. Other security updates include LibreSSL, Firefox, Chromium, and Qt5 Webengine. You may run the update with pc-updatemanager pkgupdate or download the latest version on their website.
The TrueOS team is pleased to announce the availability of a new STABLE release of the TrueOS project (version 18.03). This is a special release due to the security issues impacting the computing world since the beginning of 2018. In particular, mitigating the “Meltdown” and “Spectre” system exploits make it necessary to update the entire package ecosystem for TrueOS. This release does not replace the scheduled June STABLE update, but provides the necessary and expected security updates for the STABLE release branch of TrueOS, even though this is part-way through our normal release cycle.
Important changes between version 17.12 and 18.03 …..
