Mozilla has announced that it will begin sending versions Firefox every four weeks in the new year. To prepare for the new release schedule, the company is slowly closing the gap in the upcoming releases, reducing the cycle of seven to six weeks, then five weeks and finally to four weeks. The process will completely change to a four-week cycle with the release of Firefox 74, which is expected on March 10, 2020.
According to the company, the calendar Extended Support Release (ESR) will not change, and expects to release a major new version of ESR every 12 months with an overlap of 3 months support allows updates in all businesses. The next significant emissions of ESR are scheduled for June 2020 and June 2021.
Discussing the new release cycle, Ritu Kothari Mozilla, said:
"The shorter release cycles provide greater flexibility to support product planning and priority changes due to the requirements of the business or market. With four-week cycles, we can be more agile and faster sending features, applying the same rigor and due diligence necessary for a stable and high quality publication. In addition, we offer new features and implementation of new APIs in the hands of developers faster. "
With some new features, Mozilla says it will continue to do A / B testing. This will allow the company to test products among a wider audience before finally distribute them to all users. These experiments are not currently linked to the release cycles nor be when the new Mozilla calendar goes into effect next year.
With the change, users will get new functions two weeks earlier than normal. It is unlikely that stability is affected in some way by testing A / B and phased launch strategy, in which each new version is tested by those who run Firefox Nightly, Beta Y Developer Edition. The change will mean that other projects that rely on Firefox and Tor Browser and OS Tails, will also have to slightly alter their schedules.
