The Optimization Update was a major update to Simburbia, which went into effect on July 12, 2014, while Simburbia was still in development.
Before this update, in the Main Menu was an option to calculate the audit, or all the stats about the city shown in the Side Bar (money, income, population, etc.) and it took 20 seconds to calculate. After the update, all of that 20-second calculation was now done at the end of each month, shown on the Calendar, taking only 0.667 seconds. Also, the Build Token Return was replaced with the Government Grant and One Time Tax Levy buttons.
- The update is technically called the Optimisation Update, with an 'S' because Jigarbov, the creator, is from the UK.
