## Commercial License

An enhanced version of GoAhead is available called Embedthis GoAhead Enterprise
Edition. This edition uses a commercial license and provides a royalty free,
license to embed the software into your products with options for ongoing
maintenance and support. Contact [sales@embedthis.com](mailto:dev@embdthis.com)
for details.

## GoAhead 2.X License

GoAhead version 2.X is obsolete.  If you are using version 2, you cannot apply
code or patches from the GoAhead version 4 code base as the GoAhead 2.X license
is incompatible. You must either adopt a commercial license for GoAhead version
4 or use the GPL license. You cannot extract patches from this repository and
apply to GoAhead 2 code.

While the GoAhead 3/4 APIs are different in syntax, the underlying
functionality is the same, the upgrade to version 4 is quite easy.
