Actually, it's not a real "program", but an opportunity for developers and users to test drive new versions of X-Cart 5 before the versions become available for other X-Cart users.
Starting with the next version (5.2.4) we will roll out updates in two waves:
1. Once we make an official release announcement, the new version becomes available for "early adopters" only.
2. A few days later (depending on results of the first wave) we open the update to the rest of the X-Cart community.
There will be one more wave ("zero" wave) used for testing purposes before the official announcement. But most of you will never notice it (at least we think so
).
[ ! ] If you want to be in the first wave for the next 5.2.4 version, please reply into this forum thread.
Do NOT post your license keys there! Just write something like "I'm in" and we will add you to "early adopters".
The 5.2.4 version will introduce a new setting that will allow you to make this decision on a per-store level.
