Changelog

All notable changes to Tandem T6. Versions follow Semantic Versioning.

[Unreleased]

[1.0.0] - 2026-10-18

First public release. The car, plugin, sounds, text and settings are the same as 1.0.0-rc.5; the only change in the zip besides the version is the tip line in LICENSE.txt (an optional Ko-fi link that unlocks nothing).

Added

• Tandem T6, an add-on car (tandemt6) for GTA IV: The Complete Edition 1.2.0.59. No stock car is replaced.
• Tandem seating: the driver in front and one passenger behind, both through the front doors. Hold Enter vehicle next to a friend's Tandem T6 to ride in the back.
• Battery-weight stability: very hard to roll, still spins and drifts, and rights itself after big crashes.
• Live stats on screen: power, speed, motor rpm, body roll and cornering g, with automatic 0-60 mph, 0-100 km/h and quarter-mile timers and a best-times card.
• 20 original sounds: motor, launch, doors, seat, wind, rattles and impacts.
• Body damage and deformation like the stock cars.
• Every setting in plugins/TandemT6.ini, reloadable while you play.

• Works alongside the Liberty City pack: its menus pause the car's controls and on-screen hints.

Known issues

• The horn, engine and tyre-skid sounds from the game itself are not included. See the README.
• Developed and tested on a Mac with CrossOver. Windows should behave the same; please report anything that doesn't.

[1.0.0-rc.5] - 2026-10-18

Release candidate: the build the author tests on a clean game copy before the first public 1.0.0. The model, sounds, text, settings and handling are the same as rc.4.

Changed

• The plugin also recognises the Liberty City pack's core plugin (LibertyCityCore.asi). With the pack installed, its menus pause the car's controls and on-screen hints, as they do on their own.

[1.0.0-rc.4] - 2026-10-18

Release candidate: the build the author tests on a clean game copy before the first public 1.0.0. The car, plugin, sounds and text are the same as rc.3.

Changed

• The zip's README.txt, LICENSE.txt and CHANGELOG.txt are now made from the mod's wiki pages: README, install guide, controls, credits, terms and changelog, so the download, this page and the mod pages say the same.

[1.0.0-rc.3] - 2026-10-18

Release candidate: the build the author tests on a clean game copy before the first public 1.0.0. Zip: TandemT6-1.0.0-rc.3.zip (its SHA-256 is in the release notes and in the zip's SHA256SUMS.txt).
