Buildroot 2017.08 is released - Go download it at:

Please give it a spin and report any problems to the mailing list or
bug tracker.

This was another big development cycle with close to 1600 changes all
over the tree and more than 100 unique contributors! I'm very happy to
see so many "new" people next to the "oldtimers".

Of noteworthy new features/changes we have:


- The skeleton package has been split into multiple packages:
  skeleton-sysv (when Busybox or SysV init are used),
  skeleton-systemd (when systemd is used), skeleton-none (when
  no init system is used) and skeleton-custom (when a custom
  skeleton is used). Those packages, except skeleton-custom,
  share common logic and data in a new package called
  skeleton-common. The skeleton package becomes a virtual
  package. This change allows to generate a filesystem that is
  compliant with systemd expectations.

- Support for using a read-only filesystem with systemd has
  been fixed.

- Major revamp of the gettext handling, with user-visible

  - prior to this revamp, when BR2_ENABLE_LOCALE=y, each
    package could decide to enable or not NLS support. When
    BR2_ENABLE_LOCALE was disabled, NLS support was forced off
    by passing --disable-nls to packages.

  - after this revamp, a new BR2_SYSTEM_ENABLE_NLS option
    controls whether NLS support should be enabled or not in
    packages. This option defaults to disabled, which means
    that now, NLS support is by default disabled in all

  Therefore, if you need NLS support in packages, you must now
  explicitly enable the BR2_SYSTEM_ENABLE_NLS option.

- The host directory no longer has a usr/ component. This
  makes it much more natural to use that directory as an
  externally used toolchain. For compatibility with existing
  scripts, a link usr -> . is still added.

- Hashes are now checked on tarballs by Buildroot when a
  package is sourced from a Git repository.

- Patches are no longer being downloaded from Github, since
  auto-generated patches could change over time, and break
  hashes. All patches that were downloaded from Github are now
  stored in their respective package directories.

- Hash files in packages can now contain hashes for the
  license files contained in the package source code. This
  allows to detect changes in such license files.

- Binaries in $(TARGET_DIR) are now cleaned up from invalid
  RPATHs at the end of the build.

- A new "make sdk" target prepares $(HOST_DIR) to be
  relocatable: turns RPATHs in host binaries into relocatable
  ones, removes bogus RPATHs from staging binaries/libraries,
  and provides a relocate-sdk script that can be executed to
  relocate the SDK after installation.

- Addition of utils/genrandconfig which generates a random
  configuration based on a set of pre-defined toolchain
  configurations (support/config-fragments/autobuild/) and a
  random selection of packages. It is now used by the
  autobuilders to generate the random configurations.


- ext2/3/4 filesystems are now generated using mkfs.ext from
  e2fsprogs instead of using genext2fs.


- Addition of support for ARM big.LITTLE variants
- Improved MIPS support, with options to select NaN encoding
  and FP32 mode.


- Switch to gcc 6.x as the default gcc version, add support
  for gcc 7.x, remove support for gcc 4.8
- Switch to binutils 2.28 as the default binutils version, add
  support for binutils 2.29, remove support for binutils 2.26
- Support added for gdb 8.0
- uClibc-ng bumped to 1.0.26
- CodeSourcery toolchains for x86 and SuperH have been
  removed, they were using a too old glibc version
  (2.17). External toolchains with glibc 2.17 or earlier are
  no longer supported.
- The version selection in the glibc package has been
  removed. Like musl and uClibc-ng, we now use the latest
  glibc version.
- Improved support for Xtensa toolchain overlays, which can
  now be downloaded.


- Numerous improvements to the runtime test infrastructure
- Tests are now executed by Gitlab CI on a regular basis
- Tools that are directly useful to the user have been moved
  from support/scripts/ to utils/: brmake, check-package,
  get-developers, scancpan, scanpipy, size-stats-compare,

New defconfigs: A13 Olinuxino, Engicam platforms (i.CoreM6
Solo/Dual/DualLite/Quad, RQS SOM, GEAM6UL SOM, Is.IoT MX6UL
SOM), Nano Pi M1 (Plus), OrangePi Zero and Plus.

New packages: azure-iot-sdk-c, cracklib, dt-utils, easy-rsa,
erlang-jiffy, erlang-p1-oauth2, erlang-p1-xmpp,
ifupdown-scripts, irrlicht, kodi-inputstream-adaptive,
kodi-inputstream-rtmp, kvazaar, let-me-create, libloki,
libpwquality, libressl, libspatialindex, libva-utils,
linuxconsoletools, linuxptp, luaossl, lua-sdl2, lua-stdlib,
lsscsi, paxtest, pcre2, pixz, python-asn1crypto,
python-backports-shutil-get-terminal-size, python-bcrypt,
python-cheroot, python-h2, python-hpack, python-hyperframe,
python-hyperlink, python-ipython-genutils, python-pathlib2,
python-pickleshare, python-priority, python-portend,
python-scandir, python-systemd, python-tempora,
python-traitlets, python-typepy, qt5virtualkeyboard,
ratpoison, rauc, refpolicy, rhash, sdl2_mixer, sdl2_net,

Once again our autobuilders have helped us fix a huge amount of build
issues. Thanks to all the people reviewing failures and fixing issues:

The next release will be 2017.11. Expect the first release candidate at
the beginning of November and the final release at the end of the month.

This release will be supported with security and other important fixes
until 2017.11 is out. If you need longer support then consider using our
long term support release (2017.02.x) instead which will be supported
until 2018.02.
