Patterns: what to expect from future updates
- Timing. Recent updates landed on Saturdays (US time). One update in late August arrived a day late, which the developers acknowledged with a code.
- Codes. Most updates come with one or two new codes, and older codes expire quickly. Redeem new codes the day they appear.
- New cars. Almost every update adds cars. Some go straight into junkyards; others are tied to auctions, Cars & Bids or the Store.
- Balance changes. Junkyards, auction odds and quick travel have all been rebalanced after release, so advice from older videos can go out of date.
- Previews. Content creators often show sneak peeks before release. We only log features once they ship.
