Any additional Information

When the version of Rocket.Chat was raised from 3.12.0 to 5.4.10,
Chat is now linked under the following conditions.

“Any one character” + “.” + “2 or more arbitrary characters”

For example)
1,Linked pattern
aa.aa
aa.aa

2,Not linked pattern
a.a

Can you tell me what function or esue is causing this?
Or is this caused by some specification change in the 5.4.10 version?
I’d be glad to hear from anyone with knowledge of this.

Just in case, I will also share an image of the actual screen. Please refer to it if you like.

5.x is not supported so we can’t really help you.

You need to be on at least 6.6.x
