<p class="MsoNormal"><span style="font-size:11.0pt">Hello Yu,<br>
<br>
There were three things changed that you have mentioned here. I'll<br>
try to clarify theses.<br>
<br>
- option-class-tagging<br>
(<a href="https://kea.readthedocs.io/en/kea-2.7.5/arm/classify.html#option-class-tagging">https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fkea.readthedocs.io%2Fen%2Fkea-2.7.5%2Farm%2Fclassify.html%23option-class-tagging&data=05%7C02%7Cyu.xiao%40cox.com%7C13f3cc3e7ef34889359508dd34aba747%7C9feebc97ff0442c9a152767073872118%7C1%7C0%7C638724634039859910%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=HO0Ms2q8RsYqsewLVZpP3NYqa2kt3AoubgvLgdnBHII%3D&reserved=0</a>)<br>
- This is a completely new feature that allows the use of a class<br>
guard ("client-classes": [ <list> ]) inside of an option. This limits<br>
the option availability to only those clients that are members of one<br>
of the classes in the list.<br>
- client-class -> client-classes - the former "client-class" is now<br>
"client-classes" and is a list. This allows you, for example, to<br>
allow members of more than one class to obtain an address from a pool.<br>
No longer will you have to make meta-classes testing membership in<br>
several other classes. For an example of this change, see:<br>

- require-client-classes -> evaluate-additional-classes - This change<br>
is merely a renaming to make it more clear what the functionality<br>
actually does. The naming was unclear before and led to confusion<br>

> Last year, during my testing, I found that we can configure one client class string to a subnet definition, but the configurations won’t be changed. Since then, I have seen some similar discussions. And there’s a new feature in 2.7.4 called Option Class-Tagging
which allows us to give different subnets different specific configurations. Also, the keyword has been changed from "client-class" to "client-classes". It looks to me, now we can assign multiple client classes to one subnet. But I don’t know if this is just
a placeholder for now, or it has already supported the “OR'ed list of classes”. Can you help clarify?<br>

> And it also mentions that "client-class" will be changed to "require-client-class" in future versions. When will it be made to the next stable version? Thank you.<br>
