[Csnd-dev] plugin opcodes / API Changes

As a first approach to making plugins compatible with csound7: is there any
document regarding the changes in the API exposed for opcodes (methods
renamed, removed, etc in the csound struct)?

At a first glance, I have problems with the following:

* GetSr is missing. There are some ugly macros, like CS_ESR which seem to
do the "right" thing, should plugins use that?
* GetKr: same as GetSr
* GetInstrument is gone. Was it renamed? Or is it no longer possible to
provide the functionality?
* RegisterDeinitCallback is gone. How can a plugin implement this?
* insert_score_event_at_sample
* GetInputArgCnt
* GetInputArgName
* GetOutputArgCnt
* hfgens

cheers
