The centering change applies only to the new component syntax, with an updater tool handling migration. On sizing, the team is seeking community feedback on whether constraints should propagate from all children or only layout children. For purity, a `pure` keyword for callbacks and public functions is proposed, with auto-detection for private functions, drawing parallels to Rust's `unsafe` blocks as a potential escape hatch. Slint 0.3.4 is the first version to include all these improvements. ## Full article daily.dev links to this article rather than hosting it.
