Version 0.6 'Simon' .... development version
QGIS Change Log
2005-04-10 [timlinux] 0.6devel11
** Data binding on projection and ellipsoid selector on custom projection
dialog
2005-04-11 [ges] 0.6.0devel10
** Applied patches from Markus Neteler to allow compilation on Qt 3.2
2005-04-11 [ges]
** Fixed default projection (WGS 84) so it is now selected when the
project properties dialog is opened and no projection has been set.
2005-04-10 [timlinux]
2005-04-10 [timlinux] 0.6devel9
** Added custom projection maker dialog to main app menu. Dialog is still
under construction.
