v1.5.2

patchrb-mechanicMay 12, 2026

Dealership API polish + idle CPU shave.

Patches the dealership API stability issues a handful of servers hit on go-live, and tightens up the QBCore-era vendor migration path. Idle CPU drops another 0.004ms per tick on a 64-slot.

Fixes

fixDealership API: race condition when two players triggered a sale simultaneously.#312·8f2a1c3
fixVendor migration: handle the 0-length address edge case from QBCore-era saves.#308·b91d4e0

Performance

v1.5.1

patchrb-mechanicMay 04, 2026

First post-1.5 hotfix wave.

Three regressions caught in the first 48 hours after 1.5 went stable. Nothing data-corrupting — but the towing inventory leak was annoying enough to ship same-day.

Fixes

fixTowing: stash inventory was held open after disconnect on long sessions.#305·44c0b8e
fixVehicle handling preset reload no longer flashes the engine state for one frame.#303·df1129a
fixDealership: NPC rotation reset to (0,0,0) after server restart.·2a6fbb1

v1.5.0

minorrb-mechanicApr 28, 2026

The dealership update.

Long-promised: a first-class dealership API, custom vendor configs, and a from-scratch test-drive system with waypoints and time limits. Compatible with QBCore and QBox out of the box.

Highlights

Dealership API — `mechanic.dealership.*` exposes vendor + sale lifecycle hooks.
Test drives — waypoint routes with configurable time limits per vendor.
QBox bridge layer ships at parity with QBCore.

Features

featDealership API for custom vehicle vendors.#287·9d4ae31
featTest-drive routes with named waypoints and per-route time limits.#291·67c1f02
featQBox bridge layer at parity with the QBCore bridge.#294·12a78de
featShowroom layouts now reference NAMED anchor points instead of magic indexes.#285·f5a8901

Fixes

fixTrunk inventory: missing items after `setMaxWeight` on the fly.·7c4d0b9

Performance

perfVehicle catalog cache rebuilds incrementally instead of all-at-once.·3e98aab

Breaking

breakingShowroom config: anchor indexes are removed. Run `mechanic:migrate-showroom`.#286·c012b41

v0.9.0-rc.1

previewrb-housingApr 19, 2026

rb-housing — public beta.

First public surface of rb-housing. Interiors load on-demand, keys are first-class objects, and the realty MLS UI works in both Cfx and standalone NUI shells. Expect breakage on the storage layer through 0.9.x — alpha keys WILL be re-issued at 1.0.

Highlights

On-demand interior streaming — only the players inside an interior pay the cost.
Keys as first-class objects: lend, revoke, expire, audit.
MLS-style realty UI lives in `rb-housing/ui`.

Features

featOn-demand interior streaming.#261·21e5cd6
featKeys-as-objects API: `housing.keys.issue/revoke/audit`.#264·82bd0a4
featMLS realty UI: search, filter, and tour listings in-game.#270·fd1c4b8
featDoorbells! `housing.bell.ring` posts a notification to whoever holds the keys.·0a91f55

v1.4.3

patchrb-mechanicApr 09, 2026

Anti-cheat hardening.

Two server-authoritative checks that a small number of bad actors had found ways around. Both moved entirely server-side. No client signal is trusted; if you'd patched custom client-side checks, you can remove them.

Fixes

fixReceipt UI no longer flashes the old price for one frame on quick sales.·5519027

Security

securityMove vehicle-mod authorization fully server-side; no client hint trusted.#248·ab123cd
securityPricing math runs on the server; client never sends a `price` field.#249·e0f93a2

v1.4.2

patchrb-mechanicMar 22, 2026

Held the bug. Shipped the rest.

We held a bug back from this release on purpose — the one where rapid-cycling the lift caused a cosmetic snap on the body kit decal. It's reproducible only on certain GPU drivers and we wanted another two weeks of data before the fix. Everything else is in.

Features

featMechanic notebook UI: bookmark frequently-used parts.#231·73aa1c8

Fixes

fixTow truck winch detaches cleanly when the towed vehicle despawns mid-tow.·918fe22

Performance

perfCache mechanic-bay occupancy queries; -0.006ms per tick.·4d20a13

Chores

choreBump bridge dependency for QBox 2.4 compatibility.·bbf01c5

v0.3.1

patchrb-vehicleshopMar 15, 2026

Showroom anchor migration.

Last patch on the magic-index showroom config. The 0.4 line moves to named anchors only; this release supports both with a deprecation warning so you can migrate at your own pace.

Features

featNamed anchor points (forward-compatible with rb-vehicleshop 0.4).#198·6691d22

Fixes

fixShowroom NPC spawning on dedicated boxes with low player counts.·ca0d8e1

Internal

refactorInternal: extract anchor resolver into its own module.·f3a01c4

v1.4.1

patchrb-mechanicMar 04, 2026

Quiet week.

Three small fixes, no new surface. The kind of release we like best.

Fixes

fixJob inheritance: child jobs no longer inherit parent's max-bay count.·0b8c4d1
fixNotification z-index above the radial menu.·199cc8e
fixConfig: `Config.Debug = true` no longer leaks to clients in production builds.·2f4ae09

v1.4.0

minorrb-mechanicFeb 19, 2026

Diagnostic mode.

A new diagnostic mode for server owners — `mechanic:diagnose` dumps a structured report of every tick budget, cache, and pending event in the system. Built for the people who run the servers, not just the people who play on them.

Highlights

`mechanic:diagnose` console command — per-system tick budget snapshot.
Structured logs land in `logs/mechanic-<date>.jsonl`.

Features

featDiagnostic mode + jsonl structured logs.#178·44e8b0c
featLive tick-budget overlay for opted-in admins.#181·ce120ab

Fixes

fixGarage indexing: handle interior plates with non-ASCII characters.·30bb6a1

Performance

perfEvent batching for vehicle-state updates: 4x fewer net packets at peak.·771fb5d
