Or get it from Git:


Buildroot 2021.02.2 is a bugfix release on the current long term
release, fixing a number of important / security related issues
discovered since the 2021.02.1 release.

- support/scripts/cve.py: Use the (significantly) faster yajl2
  ijson backend for older (< 2.5) ijson versions rather than the
  slow python default, speeding up pkg-stats by ~2x.

- CMake infrastructure: Use CMAKE_EXE_LINKER_FLAGS rather than
  CMAKE_CXX_FLAGS to link with libatomic to fix an compatibility issue
  with poppler.

- Infrastructure: Expose CONFIG_DIR to post-build/post-image scripts, so
  they can call the Buildroot Makefile in the correct directory for both
  in-tree / out-of-tree builds.

- CPE meta data has been added for a large number of packages

- Security fixes for bind, cifs-utils, clamav, dnsmasq, exim, ffmpeg,
  go, hostapd, libnpupnp, libupnp, nettle, openvpn, php, python-django,
