+Sketchup.require 'sketchup'

+
+# 1.1.0 Support 8-bit ubyte indices
+#       Fixed exception handler
+#				Fixed an issue for when the json text contained utf8 multibyte characters
+#	1.1.1 Fixed inversed textures
+#       Fixed metallicFactor default value - textured materials had default metallicity of 1 (metal) rather than 0 (diaellectric)
+# 1.1.2 Add Sketchup.require
+# 1.2.0 Add file-save dialog box when exporting the model, default to the same directory and name as the existing model.
+# 1.2.1 Do not export hidden entities
+#       Export metallicFactor and roughnessFactor from dictionary attributes
+#       Allow scripted exports to specify filename
+#       Orientate model to face viewer
+#       Export textures from group/components
+# 1.2.2 Fixed issue with nil material exported in un-grouped geometry
+# 1.2.3 Do not export if the entity is on a hidden layer
+#       Fixed issue with min/max values of accessors
+# 1.2.4 sRGB to linear color space conversion
+# 1.2.5 Export sampler to correct issues with textures
+# 1.3.0 Remove support for original Microsoft .glb files, as they have now fixed their issues
+#       Allow setting material metallic, roughness, emissive, and doubleSided properties through material naming convention
+#       Add BLEND property if the material contains a texture, as it might contain alpha transparency and the Sketchup API doesn't tell us.
+#       Fixed an issue where the material from an outer group or component being used to paint nested faces was not used in the final model.
+#       Set glTF copyright field from model.description
+# 1.3.1 Drop the use of 8-bit indexes as this is not supported by many GPUs/Engines and may be dropped from future glTF specification.
