We were running behind and there were quite some deprecations to update. This was mostly in the upstream copy/pasta package but seems quite minimal.

// 1. Support for legacy color values separated by semicolons (;) with respect to RGB, and indexed colors

// 3. Support ignoring and omitting the 6th parameter with respect to RGB and CMY colors
