This is a major release that introduces new features, including one highlighted in the release notes: "The v4.2 release introduces a powerful new Direct Routing capability that allows inputs to specify routes directly to outputs, bypassing the traditional routing mechanism." But it also brings some security fixes. Not all of them are relevant, but some piece of lecture can be found here [1]. It fixes the following CVEs: CVE-2025-12977 CVE-2025-12978 CVE-2025-12972 CVE-2025-12970 CVE-2025-12969 News: - https://fluentbit.io/announcements/v4.1.0/ - https://fluentbit.io/announcements/v4.1.1/ - https://fluentbit.io/announcements/v4.2.0/ The patch 0001-plugins-kafka-fix-cmake-cross-compile-error.patch can be dropped as it has been merged upstream [2].

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
