#### It’s Back: Ext JS Single Developer License ##### Single Developer Subscription License – FAQs: > When will single developer licenses be available for purchase for GXT and Sencha Test? > 什么时候可以为GXT和Sencha测试购买单个开发人员的许可证? This will be an area of focus for 2018. In the meantime, Independent Consultants who meet the eligibility requirements may purchase fewer than five licenses of Sencha Test and GXT under our Independent Consultant program. 这将是2018年的重点领域。与此同时，符合资格要求的独立顾问可以在我们的独立顾问项目下购买少于5个`Sencha Test`和`GXT`的许可证。 > I am a current Ext JS customer and have purchased a 5-pack of Ext JS licenses and am not using, nor do I plan to use, all 5 licenses. What should I do? Please contact your Sales rep in advance of your renewal to discuss the best package for you. You will have the option to maintain your 5-pack license package or you can switch over to the correct number of Single Developer Subscription Licenses that best suit your development team/organization. For a small team it maybe still be more economical to keep your existing renewal. > Do I need to renew my license every year when purchasing Single Developer Subscription licenses? Yes, if you have purchased Single Developer Subscription licenses, you will need to renew your license, which includes maintenance and support, on an annual basis. > Are x-credits going to be included with Single Developer subscription license purchases (similar to the 5-pack Ext JS purchases)? Yes, you will receive 40 x-credits with each license purchased under the Single Developer subscription license (same as the 5-pack Ext JS license purchases). > I have previously purchased Ext JS licenses under the Independent Consultant License program. Now that you’re offering Single Developer Subscription Licenses (as of 12/1/2017), how does this impact my usage of current Ext JS licenses under the Independent Consultant License program, and what happens when my license expires? There’s no change to the status of your Independent Consultant License program license. You can use this license for a customer if you have not already assigned it. When Sencha went to the five (5) user license minimum, they grandfathered all of the existing users holding single user licenses so that they could continue to hold their single user license as long as they continued to pay their annual maintenance renewal fee. Will this policy continue for those users or will they be required to switch to the new single user subscription model? They will continue to be grandfathered in and will not have to switch over to the subscription license * * * * * 购买链接： [Sencha Ext JS Single Developer Subscription](https://www.sencha.com/store/extjs-subscription/)
