This is actually an issue on tslib package:

microsoft/tslib#135

[ezolenko]

Should be fixed in 0.31.0

@ezolenko, I am still seeing the same issue even with rollup-plugin-typescript2==0.31.1:

(node:68636) [DEP0148] DeprecationWarning: Use of deprecated folder mapping "./" in the "exports" field module resolution of the package at  *****js/node_modules/rollup-plugin-typescript2/node_modules/tslib/package.json.

yarn info rollup-plugin-typescript2
yarn info v1.22.17
{
  name: 'rollup-plugin-typescript2',
  description: 'Seamless integration between Rollup and TypeScript. Now with errors.',
  'dist-tags': {
    latest: '0.31.1'
  },

@leikoilja
What's your versions in plugin output? This part:

rpt2: typescript version: 4.2.4
rpt2: tslib version: 2.3.1
rpt2: rollup version: 2.48.0
rpt2: rollup-plugin-typescript2 version: 0.31.2```

@ezolenko, thanks for getting back to me:
So, yarn list yields:

├─ typescript@4.5.2
├─ tslib@2.3.1
├─ rollup@1.32.1
├─ rollup-plugin-typescript2@0.30.0

Edit:
oh, flip... i dont get yarn dependency resolution logic a bit.. yarn info showed me the plugin is at 0.31.1, but now if i understand correctly it just shows the latest available version, not what i have installed.
Now that i ran yarn list is see that plugin is at 0.30.0. Tried yarn upgrade rollup-plugin-typescript2 to get the latest version but it still installed me 0.30.0, so i ended up with yarn upgrade rollup-plugin-typescript2@0.31.1, which installed 0.31.1 and bumped my package.json. And the issues is indeed fixed, no more warnings 💥 Thanks @ezolenko, sorry for the false alarm

Closing as this was a false alarm on the re-opening.

Should be fixed in >=0.31.0 per above
