When Nightly merges into Aurora every 6 weeks we lock Aurora updates at a specific old version for a period of time (days to a week) while QA runs some tests. Once their tests have passed, we re-enable updates. This document describes how to do both of these things.

Central will become an odd-numbered Gecko version

  • Repoint B2G Aurora updates at Aurora builds:
    1. Go to the Balrog Admin interface's rules page.
    2. Find the rule that has "B2G" for the product and "aurora" for the channel
    3. Change the "Mapping" for that rule to "B2G-mozilla-aurora-nightly-latest"
    4. Scroll to the right and click "Update" to make the change.

Central will become an even-numbered Gecko version

  • Point B2G Aurora updates at the newly created mozilla-b2gXX builds:
    1. Go to the Balrog Admin interface's rules page.
    2. Find the rule that has "B2G" for the product and "aurora" for the channel
    3. Change the "Mapping" for that rule to "B2G-mozilla-b2gXX_vX_X-nightly-latest" - for example, "B2G-mozilla-b2g32_v2_0-nightly-latest" was used on the merge day that created the mozilla-b2g32_v2_0 branch.
    4. Scroll to the right and click "Update" to make the change.
