New Features / Enhancements

---

• Linux kernel 4.15/4.14/4.12, gcc 7.3, glibc 2.27 and ~240 other recipe upgrades

• Reworked EFI boot support
• Replaced outdated man with man-db
• Refreshed patches across a number of recipes

• A shared state mirror is now being published on yoctoproject.org in order to accelerate builds where compatible. You will need to configure the build system to point to these - details in the auto-generated local.conf (or meta-poky/local.conf.sample).
• Added support for 32-bit and 64-bit RISC-V architectures (riscv32 and riscv64 respectively)
• bitbake-layers improvements:

* add-layer/remove-layer: add support for adding and removing multiple layers at once
* show-recipes/show-appends: support specifying more than one recipe

• devtool improvements:

- devtool: add a 'latest-version' command
- devtool upgrade: improve performance and show progress when adding files
- devtool upgrade: provide useful defaults for version/commit when upgrading recipes
- devtool upgrade now automatically handles a change in source subdirectory in the upstream archive
- devtool upgrade will now handle and report license checksum changes
- devtool find-recipe and edit-recipe now always work with any recipe
- devtool finish ensure repository is clean before proceeding
- devtool finish now has a dry-run option so you can see the changes that will be made before applying them
- devtool finish: add --force-patch-refresh to allow refreshing patch context
- devtool can now deal with conditional patches (added by way of an override)
- devtool search will now also look in the recipe cache, so it can show unbuilt recipes in the results

• core-image-minimal-initramfs now uses initramfs-framework for initialization

Known Issues

---

• Whilst recipes for Go 1.10.x are provided, the default version of Go remains at 1.9.x, as there is a serious bug in Go 1.10 when it comes to using the shared runtime support which causes problems in multiple projects. If you need to you can switch to 1.10 by setting GOVERSION to "1.10%" in your configuration. For more details on the issue upstream see:

https://github.com/golang/go/issues/24640
