Learning about whats new in 13.3

This is based on LLM Tech and a Lot More: Version 13.3 of Wolfram Language and Mathematica—Stephen Wolfram Writings. There is at least one significant difference where I couldn’t get a contour integral of Pacman to work for some reason. That is why I am creating this post, partly to ask for help on integrating Pacman.

Works fine:

ContourIntegrate[1/(z - a), z \[Element] RegionBoundary[Disk[{0, 0}, 1, {Pi/6, 11 Pi/6}]]]

(*ConditionalExpression[Piecewise[{{(2*I)*Pi, (Abs[a] < 1 && Arg[a] > Pi/6) || (Abs[a] < 1 && Arg[a] < -1/6*Pi)}}, 0], 
 (Abs[a] != 1 || (Pi + 6*Arg[a] >= 0 && 6*Arg[a] <= Pi)) && ((6*Arg[a] != Pi && Pi + 6*Arg[a] != 0) || Abs[a] > 1) && a != 0]*)

Regards.

Yes, it works for me too, but the second half of the code Disk[{0, 0}, 1, {Pi/6, 11 Pi/6}] is colored red. Syntax coloring has not been updated to the new syntax of Disk, apparently.

Yes it also works now. The syntax coloring has not been updated.
