Mon Apr 25 17:35:21 2016 UTC (7 years, 11 months ago) by schoenebeck
File size: 10853 byte(s)
* Script Editor: Added support for liblinuxsampler's NKSP parser
  backend for displaying parser errors and warnings directly within
  the source code (for now simply errors cause a red background color
  at the relevant location, and warnings a yellow background color;
  error text / warning text is not displayed yet).
* Bumped version (1.0.0.svn4).
