router-link generated cause warning from vue-router

After update vue-router from 3.1.5 to 3.5.1 got warning in console:

[vue-router] <router-link>'s tag prop is deprecated and has been removed in Vue Router 4. Use the v-slot API to remove this warning: https://next.router.vuejs.org/guide/migration/#rem

b-nav-item (at least) with property “to” cause router-link generation. As far as I see vue router is preparing for the switching to new version (4 I guess) and produce such warnings.

Steps to reproduce the bug

Create b-navbar with b-nav-item with property “to” used. Example: <b-nav-item to="/Orders" >Link Text</b-nav-item>

Expected behavior

Now warnings in console

Duplicate of #6373.

The issue was fixed by #6374 and will appear in the next minor version (2.22.0). That PR resolves the warnings for most users, except those that actually use the event and tag props on BLink and similar components.

I have an obsessive compulsion, so I don’t feel okay with things that aren’t perfect even though I know it’s just a warning, not an error. Sorry! Hopefully there will be no more warnings at version 2.21.3 Have you followed this docs? https://next.router.vuejs.org/guide/migration/#removal-of-event-and-tag-props-in-router-link
