I haven't finished v2.0 yet, I am working on it.
Changes so far:

* New defaults:
\epstopdfsetup{%
  append,%
  update,%
  prefersuffix,%
  suffix=-\SourceExt-converted-to%
}

* The implementation is moved to package `epstopdf-base.sty'.
  This package does not have package options.
    Package `epstopdf.sty' is a wrapper package that accepts
  package options.
  
  Thus graphics.sty should then load epstopdf-base.sty instead
  of epstopdf.sty. This avoids option clash errors:
    \usepackage{graphicx}
    \usepackage[...]{epstopdf}

* An additional configuration file `epstopdf-sys.cfg' is loaded
  if it exists. Perhaps it helps distributors providing
  another conversion rules or option settings. Then the user
  can set his own options without loosing the conversion rules.
