He committed a fix to give proper syntax highlighting for GLSL source code so the editor now correctly highlights GLSL words such as "uniform" etc.
He also improved error handling so that the shader editor will mark the line with the syntax error, and also the label that shows the error is now larger and can be expanded using a splitter control.
I think this is quite nice, so thank you Christian
