# Release of the Polish region - What we learned
1. Don't delete `en-GB` from enabled languages configuration in UserAPI, its fallback langauge for FE
2. Check config on production before release twice
3. Importer is stupid, it upserts only what you gave him nothing more.
4. There are no sports until 5 articles are inserted for at least one of them 
5. Recommended media can have old data in the seed file - check before running the migration
6. Updater is still missing functionalities - topic images upload f.e., but importer is not here to fix it (only for CS and EN)
7. Release on Thursday is not a good idea for now (two most experienced FS BE devs are not working)
8. Rememver all the deals made with PM. We agreed on importing articles next week, but then they kept pushing it on Friday
