updated work permit regulations - please help

Hello,

I've seen several articles stating that work permit holders are now allowed to engage in any work, even work not stated directly on the work permit, as long as its not one of the "Thai National only" job categories. I cannot find the official document on any government website. I'm referring to specifically,

Section 37 of Decree No. 2 repealed Sections 70, 71, 72 and 73 of Decree No. 1. Furthermore, Section 28 of Decree No. 2 provides that a work permit holder may engage in any work that is not specifically prohibited to all foreigners on the “Official List” of work prohibited to foreigners. The Official List outlines, the limited number of activities for which a foreigner cannot obtain work permission for in any case. 

If anyone can provide me a link to this document or official claim from a government website, it would be greatly appreciated.

Thank you in advance :)
