v4.0
Rejoice all! Finally a new version other than a 3.x.x iteration!
- Renamed the mod from "Unrestricted Air Horns + Train Horn" to Unrestricted Air Horns + Extra Horns"
- Updated the format of the "horn.sui" file to follow the current vanilla format. No impact on gameplay, it just looks better and easier on the eyes when editing.
- Made small changes to the Train Horn.
-- Increased price from $570 to $1000.
-- Increased unlock level from level 3 to level 10.
- Added new add-on air horns:
* Mack Horn (utilizing the Mack Anthem/Pinnacle default air horn).
-- Unlocks at level 11.
-- Priced at $1010.
* Freightliner '24 Horn (utilizing the Freightliner Cascadia Fifth Gen (2024) default air horn).
-- Unlocks at level 12
-- Priced at $1020.
- Added Black versions of all existing and new horns.
* Note: This excludes the Western Star branded air horn. It does not have a Black model/texture in the vanilla game.
- Updated descriptions to match the changes.
- Cleaned up the descriptions a slight bit.

v3.1.15
- Updated descriptions for the Freightliner Cascadia (now denoted in-game as 2019) and the recent Freightliner Cascadia Fifth Gen (denoted as 2024 in-game).
NOTE: The Horn Adapter slot for the 72" Sleeper XT cabin for the Freightliner Cascadia 2024 is currently broken and does not actually add slots. This is a vanilla bug that SCS has to fix.
