Yes. Any version number beginning with 1.0.0 through 1.9.9 is covered by the 1.x license and you may build and deploy
any number of applications using any versions in the 1.x range under the same license. If a new major version of Extensible is released
(e.g. 2.0.0) then an upgrade license may be required at that time to distribute applications under Extensible 2.x.
Extensible is dual-licensed just like Ext JS, under both open source (GPL v3) and commercial licenses. If you do not plan on
making your application open source under the terms of the GPL then a commercial license is required per developer. For complete details see our
Generally speaking, you should be licensed for the same number of developers for Extensible that you have licensed for Ext JS.
However you do have added flexibility to get exactly the number of licenses you need which might not always match up with the options
available from Sencha (e.g., for 7 developers you could buy a 5-pack and 2 individual licenses).
Yes, you may purchase licenses and support in any combination you want. If you plan on using Extensible under the open source GPL
license you may still choose to purchase a support subscription if needed. This is a great way to still support the
project even if you don't require a commercial license.
Licenses are royalty-free, and are perpetual for the major version of Extensible that you license (e.g., 1.0), including minor version updates
for that major version (1.1, 1.2, etc). Any subsequent major version release (e.g., 2.0) may require an upgrade fee.
