（很急）请问有人知道这啥意思不？关于487转887的条款变更

这个会有重大影响关于将来487转887吗？487转887不是本来就要求在塔洲3年内待满2年，并有1年工作经验吗？
不是很理解这段话的意思。希望高人帮忙解释下。

Changes for applicants for subclass 475 and 487 – 17 December 2010
Applicants for subclass 475 and 487 visas who applied between 1 July 2010 and 1 January 2011, and whose visa was granted in this same period, are not subject to conditions 8539 or 8549 which require the applicant to live and work in specified regional areas. This affects the ability of applicants granted visas in these circumstances to subsequently apply for a Subclass 887 visa.

Changes will take effect on 1 January 2011 which enable applicants in this position to apply for the Subclass 887 visa, provided they meet the requirements of living and working in a specified regional area.

其实还是和以前一样的要求！
