General / File handling

bug fixes:

• edges were visible through faces on newer devices (with Adreno GPU)
  
• repeated textures were generated when exporting .obj files
• .spa files sometimes got huge when working longer on a scene
• issues with merging files
• normals- and smoothing-related issues
  
• lights disappeared sometimes
  
• several issues with undo
  

improvements and new features:

• several new helpful status-line messages

Viewing and navigating

The "3d-pointer" is renamed to "tripod", and the "2d-pointer" to "picker".

• the tripod now stays the same size on any zoom level
• unhiding objects and faces was not working sometimes
• V>default view, F>new scene, or loading a scene now always correctly reset the view and pointer position
• tilt-view now works smooth even with very large scenes

improvements and new features:

• lines to indicate the touch-areas (can be turned off in the preferences)
• larger default and maximal possible tripod size
• possibility to freeze objects: V>freeze selected, V>unfreeze all
• option for orthographic projection:V>orthogr. projection
• option for backface culling in the preferences

Drawing lines and curves, Creating primitives

bug fixes:

• issues with spline drawing
  

Selecting

bug fixes:

• invisible elements behind the camera were selectable; this made modeling from inside objects impossible
  

improvements and new features:

• unselect lasso and unselect paint tools added: uns. lasso and uns. paint
• the lasso tools now work with object selection also
• spline handles can now be selected in edge selection-mode also

Transforming

bug fixes:

• mirrored and merged objects got black sometimes
  
• errors with copying faces
• several snapping issues
  

improvements and new features:

• tool for easier repeated extrude added: rep. extr.
• reference CS management completely redesigned; it now resembles 3ds Max:
  The ref. CS tool sets the coordinate system used for displaying and typing coordinates, and orients the tripod accordingly. The ref. pos. sets the tripod position, i.e., the transform center for rotating and scaling, and the snap position for moving.
  
  The following commands are available when ref. CS is active:
  - selection (only for vertex-, edge- and face-selections): the the y-axis of the CS is aligned with the average normal of the affected faces
  - object: use the CS of the active object
  - each (only for objects): for every selected object, its own CS is used
  - parent (only for objects): use the CS of the "common" parent of the selection (or the world CS if there's none)
  - world: the world CS is used
  The following commands are available when ref. pos. is active:
  - active (only for vertex-, edge- and face-selections): the center of the active (last selected) face, edge, or vertex is used
  - selection: the center of the selection is used (for objects the pivots are averaged)
  - center (only for objects): the center of the respective vertices is used
  - object: use the CS origin of the active object
  - each (only for objects): for every selected object, its own CS origin is used
  - parent (only for objects): use the CS origin of the "common" parent of the selection (or the world CS if there's none)
  These settings are remembered and applied at each subsequent selection.
  
  If ref. CS is set to each, ref. pos. also becomes each, but not the other way round.
  After moving the tripod with the ref. CS tool active, if the view is tapped, the reference CS and the tripod stay at the respective position and orientation, if the ref. pos. tool is activated, the tripod is reset to the position where it was before invoking ref. CS, but retains the ref. CS orientation. While this sounds complicated, trying it out will show it is convenient this way.
• command to set the CS of objects (the "pivot") added: set obj. CS (available when ref. CS or ref. pos. is active) sets the CS of the selected objects to the tripod
• the status bar now displays the rotation and scale, the scale is typed as %

Color picker

bug fixes:

• no more duplicates in recent colors

Textures

bug fixes:

• several issues with the UV tools; also, UVs can now be moved with two fingers directly after selecting
  

Organizing, multiplying and arraying objects

bug fixes:

• copy / inst. repeat defaults to 1 now

Preferences

improvements and new features:

- the preferences now can be accessed via a "rim" like the scene explorer
- individual line size settings for tripod, picker, ...
- option to hide the Android status bar
- values can now be typed by tapping the figures

...and several other small fixes and improvements
