  • BREAKING CHANGE! -- THe API function NSCLoadPlugin has been changed to take an integer to define the load-status

2008-06-?? MickeM

  • BREAKING CHANGE! -- New settings API as well as new WEBConfiguration UI (nothing is finnished yet but I wanted to check things into the SVN since it is a lot of changes now :)

2008-05-14 MickeM

  • Fixed memoryleak in the service checker.

I am really sorry I usualy write better code then this.

2008-05-11 MickeM

  • BREAKING CHANGE! -- Changed PDH options to a more uniform design:

auto_detect_pdh and dont_use_pdh_index has been removed and instead there is a new method option that takes various values.
  • Property mode set to 100644
