Build 201 has some new names such as "CurTime" has been changed to "TimeCurrent". "BarsPerWindow" is now "WindowBarsPerChart" and "ClientTerminalName" is now "TerminalName" plus a few others.
If you are running an EA that was coded for previous builds, you need to go look at MetaEditor, go to the Navigator, then at the bottom go to Dictionary and at the bottom of the Dictionary list will be "Obsolete Functions". Read through those because your EA might need to be updated.
One of my EA's would not backtest in Build 201 correctly because of the time function change. After the change it is running correctly again. If you are running an EA live like I am, that could have caused some losses.
