This update significantly expands and optimizes large areas of Guadalajara, fixing various issues for a smoother experience. The final release version of Guadalajara will be included in Reforma Extremo Beta 2, which is still a work in progress.

The new areas introduce detailed urban landscapes, additional delivery locations, and driveable main avenues in Guadalajara, such as López Mateos and Lázaro Cárdenas. These avenues are restricted to commercial traffic but allow access to loading areas. Additionally, Periférico has been completed on the south side of the city, with the northern section coming soon in the final update. Periférico includes most of the city's industrial clusters, which you can now explore.
With this new version, the first beta of Extremo will be released for free, featuring extreme roads, as shown on the map. To prevent confusion with your load, I have included the Extremo 1.8.154 file, which serves no functional purpose. Later, I will release the second beta of Extremo, which will introduce more winding roads in northern Guadalajara, along with the final version of the city.
Reforma 2.8.7 – Official Release for ATS 1.54
This version primarily addresses major fixes related to the version change. The update was challenging due to significant instability issues that required extensive corrections. Some critical areas of the project were heavily affected, but I was able to resolve these issues with minimal impact.
Notably, the Durango-Mazatlán Highway 40D and the hidden route from Canelas to Tamazula experienced the most changes and damage. Please report any bugs related to these areas. Additionally, I have implemented a new tunnel lighting effect by SCS in the same affected region, providing a fresh and immersive driving experience.
Enjoy the update, and happy trucking!

Known bugs
-Apparently there are some issues with weather, showing drastic temperature changes in the truck dash, this may be due how the map is vertically scaled, which surpases the SCS scale temperature elevation to the extremes.
-Also, the economy of the game may be affected also, due to the scale of the projkect and wideing roads makes longer routes and high paying, this may need to be addressed in the future, I couldn't find a solution.
