With Linux kernel 4.19 hitting the streets, a new version of the GNU Linux-libre kernel is now available, version 4.19, based on the upstream kernel but without any proprietary drivers. Based on the recently released Linux 4.19 kernel series, the GNU Linux-libre 4.17-gnu kernel borrows all the new features, including the experimental EROFS (Enhanced Read-Only File System) file system, initial support for the Wi-Fi 6 (802.11ax) wireless protocol, and mitigations for the L1FT and SpectreRSB security flaws.
