   - Remove the rpm/deb directories.
   - Delete duplicate files and extraneous blobs, and convert symlinks.
   - Rename tarballs to reflect current naming conventions. For example. poky-<githash>.tar.bz2 should be renamed to poky-<release_name>-<release_number>.tar.bz2
   - Generate the BSP tarballs
   - Extract the eclipse-plugin archive to http://downloads.yoctoproject.org/releases/eclipse-plugin/<M>.<m> where M.m is the Yocto version
   - Copy the adt-dev repo to the live site (For release lines prior to 2.0.)
   - Create the md5sum table for the release
  • Copy the staging directory to the downloads directory
  • gpg sign the md5sum table
  • Create release notes, finalize, get approval, and gpg sign.
  • Create the release and BSP pages on yoctoproject.org

  • Sync the release out to the mirrors.
  • Once sync out is complete, verify that pages work, and download and documentation links work.
  • Tag the repos.
  • Verify the items on the RELEASE CHECKLIST: https://wiki.yoctoproject.org/wiki/Yocto_Project_Release_Checklist
  • Post release announcement on Blog
