Tue Sep 4 11:04:56 2007 UTC (16 years, 6 months ago) by schoenebeck
File size: 55938 byte(s)
* as counterpart to latest LS commit: added experimental support to
  synchronize gigedit with LinuxSampler to avoid race conditions / crash
  while modifying data structures and playing the instrument with LS at
  the same time
* packaging fixes: don't use a hard coded path to install the LS plugin
  DLL, trying to substitute the given LS plugin directory by the
  '${libdir}' automake variable (mandatory i.e. for Gentoo ebuild) and
  include plugin/linuxsamplerplugin.h into the release tarball
  ('make dist')
* updated German translation (po/de.po)
