Maniaplanet has word on a new optional patch that's available for TrackMania 2: Canyon, Nadeo's racing sequel (thanks Frans). This post has more details, including what this changes:

It was a minor update to fix some crashes in scripts and add these changes :

• Bugfix function TextLib::ToReal
• Bugfix function MathLib::ToReal
• Bugfix function Array.exists
• Bugfixes in Manialink quads with events
• now one can use default values (from Type names) when calling a function
• new function MathLib::Abs
• now one can include without namespace (include in local namespace)
• Manialink handles XMLEncoded scripts, to allow text such as "--" to appear in a script
