To reduce the release Overhead, Mozilla has decided to discontinue Aurora channel –which is part of Firefox release cycle — and merge with Beta, keeping Devedition themes. This will happen on April 18, 2017. The company calls this as Dawn Project.

With this, the Firefox release cycle comes down to three release channels from four: Nightly > Beta > Stable. Nightly will spent an additional 6 weeks. And the Beta now becomes the first stabilization phase after Nightly (which used to be Aurora till now). This change will affect Firefox on desktop, Android, Thunderbird and Seamonkey products as well.

The Reason for Firefox Aurora channel removal

“With significant improvements in stability and performance in the Nightly channel we have determined that we tend to gain more time by testing and localizing in Nightly and stabilizing in Beta. The increased speed to market and resulting quality and stability in the Beta channel is why Aurora is going to be discontinued on April 18 (next merge day, exceptionally on Tuesday). ” Mozilla’s engineer Francesco Lodolo said in a thread on the Google groups forum.

 Developer edition will be migrated to Beta

“Between April and June, Firefox on desktop will continue to receive updates for critical security issues and the Aurora and Developer Edition populations will be migrated to the Beta update channel. On Android, Aurora users will be migrated to Nightly.”
