Since Strapi forum isn't helping, posted my question about updating heroku-18 stack in Strapi Discord community

Hey guys, Heroku keeps warning me about heroku-18 stack update for my Strapi app...

Anyone know how does updating heroku-18 stack impact Strapi?

More context:

I have a Strapi instance running on Heroku with Postgres database.

With Heroku forcing our hand to update apps on heroku-18 stack, I’m wondering what impact updating the heroku-18 stack will have on my Strapi instance.

Just asking for the overall approach:

- Approach with extreme caution and follow the steps as recommended
- Nah updating that will not impact Strapi at all. Just update.

Which option should I take? So anyone did a heroku update recently?
