Hi 👋

Just as an FYI, I think the version of Meilisearch bundled with Mimir is 1.2 (or something around there). As adding a new version takes a bit of time and adds a lot of bloat to the binary size, this probably won't happen anytime soon until I do a pretty big refactor (for native assets and other things).
