I just received the following e-mail from Sencha:

Hi,

We are proactively reaching out to people who have downloaded the GPL version of Ext JS to remind them of the proper use of the license. We are in no way saying you are misusing it, but on a regular basis we send out emails as reminders, just in case.

For your reference our GPL license has been deprecated.

What does deprecated mean exactly, since it is not possible to draw back code released under GPL license from not being allowed to be used under the license anymore?

Does it mean, that there will be no ExtJs version 8 released under GPL anymore? So far they had the policy to release every new major version after the first minor fix release as GPL. So this commitment to the community is canceled now, is this correct?

If you are using it, the use of GPL license must be prominently displayed and the code must be made publicly available.

As far as I know, this statement is wrong in parts. The GPL does not force you to make your code public. It just forces you to put it under the GPL and make it available for the people who receive the source code or built app.

Can you confirm this?

best

Marc
