Thanks to

• bobhodge For implementing horizontal scrolling sync; plus mousewheel scrolling.

• XJmichaelw For adding IsEntireLineHighlighted attribute, which when set to true, will set the entire background of a line to a given colour corresponding to the change type for that line. And a bug fix leading to a crash when a form containing the control was minimized.

• avstri for pointing out the speed up via a StringBuilder #1.

• igitur For pointing out the .NET Framework 4 level-drop requirement

• goroggy For pointing out the need for a character diff (#7).
