What are the language differences between the OpenGL Shading Language 1.00 and 1.10?

Are there unsupported commands? Syntax differences? ...

Thank you

1.00 was the version during GL 1.5 and the extensions
GL_ARB_shading_language_100
GL_ARB_shader_objects
GL_ARB_vertex_shader
GL_ARB_fragment_shader

1.10 is the version for GL 2.0

They added features like MRT
inverse, transpose matrices
refract, exp, log
........

you can see the rest in the document
