v1.08

• added support for generating high-resolution images
• fixed issue that was causing OpenGL rendering to be performed in software under Windows Vista/7
• added functionality for creating bar charts
• abundance information specified in sequence files can now be used to create quantitative pie or bar charts
• continuous colours assigned to location sites can now be propagated onto an attached tree
• labels (which are slow to render) are now automatically hidden when interacting with the viewport in order to improve responsiveness
• visual properties of trees have been improved by adding support for thick branches, optional borders, and independent control over the size of leaf and internal nodes
• added support for optional border around location markers
• all properties dialogs have been changed to a modeless, stay-on-top style in order to facilitate interactively changing properties
• font used to render labels can now be set in the Settings->Font Settings dialog
• slightly reduced loading time for all maps and significantly reduced required memory for 2D GeoTIFF maps
• the maximum terrain resolution can now be set in the Studies Properties Dialog (this can be helpful on low memory systems)
• double clicking on a chart now bring up the Locations Properties Dialog instead of the Location Set Properties dialog
• minor UI design improvements to the majority of the layer dialog boxes

v1.07

• changed licensing from Creative Commons Attribution - Share Alike 3.0 to GPL 3.0 or later

• removed menu items associated with creating and saving studies (this functionality is now scheduled for v2.0)
• added functionality to remove custom labels (right-click popup menu)
