* '''tracking-b2g18'''. This flag is used similarly to tracking-esr17 and is meant to specifically track major stability/security/usability that we'd like to fix int he v1x timeframe. The value can either be set to + (generically tracked) or for a specific 6-week cycle (19+, 20+, etc.). It's been proposed that '''tracking-b2g-v1x''' may be a better flag, as it pertains to both Gecko and Gaia.
